Sunday, November 19, 2017

The morning was mostly cloudy, quite breezy and in the low 30's. The highlights at Lake Law were Snow Geese (3-white), several Cackling Geese and Tundra Swans (11 that took flight before everyone was settled on the berm). Also found were several Green- wing Teal, a Great Blue Heron and Sandhill Cranes (heard calling somewhere south of the Sparrow Hedge). Not much activity and nothing interesting found at the Ed Center Feeders. Only typical winter birds were found including Red-breasted Woodpeckers, Downy Woodpeckers, Blue Jays, Black-capped Chickadees, White-breasted Nuthatches, American Goldfinches, House Finches and Dark-eyed Juncos. We watched an Immature Cooper's Hawk as it observed a Red-tailed Hawk ripping apart a large bird (most likely a goose) in a grassy area. The Cooper's was most likely hoping for some leftovers for its breakfast. Also found were Northern Harriers (2-hunting inside the Main Ring), an Immature Bald Eagle (perched atop a dead tree also in the Main Ring) and a large group of American Crows (15-16 in the Lab's interior). The bird of the morning was a very late Vesper Sparrow (the Lab's latest sighting by 2 weeks in almost 20 years). Dave

Friday, November 17, 2017

Partly sunny skies soon became overcast with moderate temps (mid 30's to low 40's) and moderately strong winds. Not as many Canada Geese were on Lake Law to start as other recent visits (around 1500). Also at the lake were Cackling Geese, Mallards, Green-winged Teal and Sandhill Cranes (5). Water birds found in A.E. Sea and the Sea of Evanescence were American Black Ducks, Northern Shovelers, a Hooded Merganser (1-Fem), and Great Blue Herons (6- Sea of E). Other birds in the area were a Belted Kingfisher, American Tree Sparrows, Fox Sparrows (10-15) and Dark-eyed Juncos. It was quite a good morning for raptors starting with 3 Bald Eagles (1-adult and 2-Immatures) that were seen throughout my stay, mostly over Lake Law. Also found were 2 Northern Harriers hunting in the Sparrow Hedge area. Found elsewhere were a Cooper's Hawk, Red-tailed Hawks and an American Kestrel. Highlights found around the Lab were a Snow Goose (a blue in Main Ring Lake), Horned Larks, American Coots, Red-breasted Nuthatches, a Golden-crowned Kinglet, a White-throated Sparrow and Purple Finches (2-males at Ed Center Feeders). Dave

Sunday, November 12, 2017

Overcast skies, calm winds and cool temps greeted us early. Luckily the rain held off until our departure. Among the Canada Geese and Cackling Geese on Lake Law were 4 Snow Geese (3-white, 1-blue). Other birds at the lake were Northern Shovelers (1 or 2 here, others elsewhere), Green-winged Teal (still well represented), Hooded Mergansers, a Bald Eagle (sub-adult, working the west shoreline)), American Coots, Sandhill Cranes and a Killdeer (a flyover). All other birds were found in various locations around the lab. Other than several Fox Sparrows, only the winter sparrows were found, both American Tree Sparrows and Dark-eyed Juncos. Other birds found for the morning were Wood Ducks, American Black Ducks, Ring-necked Ducks, American Crows (comments were made about how much more common they have become recently), Red-breasted Nuthatches, a Golden-crowned Kinglet, Yellow-rumped Warblers (2-3) and a flyover Red-winged Blackbird (which was missed on Friday). Dave

Friday, November 10, 2017

The morning started out in the teens and barely reached the freezing mark by early afternoon. In addition, it was partly cloudy and calm changing to cloudy and windy with occasional flurries. Lake Law was again loaded with Canada Geese and quite a few Mallards; plus American Black Ducks (pr), several Green-winged Teal and about a dozen Bufflehead (1-male and the rest females). The number of Sandhill Cranes at the lake had increased to 48. Other birds found in the Lakes/Sparrow Hedge Region were a couple of Great Blue Herons, American Coots (2-Sea of E), a Wilson's Snipe (A.E. Sea), Fox Sparrows and Dark-eyed Juncos. Sparrows found elsewhere (all sparrows were in small numbers) were American Tree Sparrows, Song Sparrows, Swamp Sparrows, White-throated Sparrows and White-crowned Sparrows. Other birds found throughout the Lab were Wood Ducks (about a dozen), a Ring-necked Duck, Hooded Mergansers (about a dozen), Double-crested Cormorants, a Killdeer (flyover), a Horned Lark, a Hairy Woodpecker, and a Yellow-rumped Warbler (in the Village). The big miss of the morning was not finding a single blackbird. The best bird of the morning was a perched Rough-legged Hawk (inside the Main Ring) being harassed by a Northern Harrier. Dave

Tuesday, November 7, 2017

Glenn was back bright and early this morning for another short trip. He reported the Canada Geese ( over 6500) were back at Lake Law and other areas this morning. Yesterday afternoon they may have been on the south side of the Lab or in the Ring Lakes. Also at Lake Law were the Tundra Swans (pr), Cackling Geese (4) and a couple of Greater White-fronted Geese. Apparently the same 25 Sandhill Cranes were also still at Lake Law. Other birds found around the Lab were Wood Ducks (3), American Black Ducks (5), Red-breasted Nuthatches (2), a Marsh Wren (calling in the A.E. Sea area) and Pine Siskins (first of the year). Dave

Monday, November 6, 2017

Dave Shemanske today reported again seeing a Bald Eagle carrying sticks to Osprey Nest 2. Glenn was in later in the day for a short trip. Interestingly he only found about 130 Canada Geese along his route (and he was at the premium Ag Fields), quite a difference from the past several weeks. At Lake Law he found a pair of Tundra Swans, an adult Black-crowned Night-Heron and a whooping 25 Sandhill Cranes (those numbers are typically only found in the fields). Other birds he found, mostly in the north of the Lab, were an American Kestrel, a Swamp Sparrow (not typically where we look for sparrows) and an extremely low count of Red-winged Blackbirds (41). I only mention the blackbirds because of their low count. Strangely this season's numbers of blackbirds in general have been quite low, maybe this cold snap will bring more down (hopefully, with some variety). Dave

Sunday, November 5, 2017

The morning was quite dreary but mild with minimal winds. As a bonus, the rain did not start until late morning. Lake Law again had loads of Canada Geese early. The variety of other waterfowl was poor. Those found were Cackling Geese, Gadwall, American Black Ducks, Green-winged Teal and Ring-necked Ducks. Sparrow activity was way down from Thursday's visit. Those found, all in small numbers, were American Tree Sparrows (most numerous and largest number this season), Fox Sparrows, Song Sparrows, Swamp Sparrows, White-throated Sparrows and Dark-eyed Juncos. About half way back to the Hedge, Peter thought he spotted a fly off Merlin. We spent most of the remainder of our tine in the area trying to relocate the bird. After a loop of the area and back at the Lake Law berm, Peter found it half way up in a small tree. After a short time this bird moved off and a second one moved up from below to fill the vacancy. The only other highlights in this area were a Northern Harrier (a flyover), a single Great Egret, and a Belted Kingfisher. Other good birds found elsewhere in the Lab were Wilson's Snipes (4), a Northern Flicker, Red-breasted Nuthatches (first of the year), Eastern Bluebirds, Cedar Waxwings and Common Grackles. Dave

Thursday, November 2, 2017

Temps were about average, winds were calm and the cloudy skies occasionally produced a light mist this morning. Sparrows in the Sparrow Hedge area were quite active, consisting mainly of Song Sparrows and Swamp Sparrows. Others found in the area, in decreasing numbers, were White-throated Sparrows, American Tree Sparrows, Fox Sparrows and a Field Sparrow. Waterfowl diversity in the Lakes Region was down. Those found were Canada Geese (easily a couple of thousand), Wood Ducks, Gadwall, Mallards, Green-winged Teal, Ring-necked Ducks, a Lesser Scaup and Hooded Mergansers (pr). Other birds of interest found in the area were Ruby-crowned Kinglets, a Golden-crowned Kinglet and a Yellow-rumped Warbler (in the cattails of all places). Later a flock of these warblers about a dozen were found. Highlights found in other areas of the Lab were a Pied-billed Grebe, Snow Geese (2), an American Black Duck, Ruddy Ducks, a pair of Cooper's Hawks (most likely the Garden Club residents), American Coots, Merlin (my 4th of the year in the Lab), Eastern Bluebirds, an Eastern Towhee, White-crowned Sparrows (probably the most numerous sparrow species of the morning) and Dark-eyed Juncos. What may have been the same Sandhill Crane family which bred in the Lab were again seen near their original nesting area. Marcia and Gail were also in this morning and had a nice mix of birds to report. Ironically, they also saw the Merlin in possibly the same tree inside the Main Ring, but they saw it about 3 1/2 hours before me. They estimated about 3000 Canada Geese were in the Ag fields on the north side of the Lab. Other waterfowl of interest were Gadwall, Northern Shovelers,and Cackling Geese. They did well with Sparrows finding an American Tree Sparrow, Savannah Sparrows (2), Fox Sparrows (6), Song Sparrows (6), White-throated Sparrows (6), White-crowned Sparrows(2) and Dark-eyed Juncos (33). Their favorite bird of the morning was a beautiful adult male Purple Finch (3 finches were found). Other birds of interest were a Cooper's Hawk, Sandhill Cranes (3), American Coots, Belted Kingfishers (pr), an Eastern Towhee and Common Grackles. Dave

Sunday, October 29, 2017

Conditions were quite good this morning being cool with mild winds and partly cloudy skies, later turning sunny. Lake Law held a good number of waterfowl including Canada Geese, Cackling Geese, Gadwall, American Black Ducks, Mallards (most to date this season), Northern Pintails, Green-winged Teal (quite a few), Lesser Scaup (15 plus)and a Ruddy Duck. Found in the Sea of Evanescence were Wood Ducks and Hooded Mergansers. Sparrows were quite active along the Sparrow Hedge paths. Those found were American Tree Sparrows (increasing in numbers), a Field Sparrow, Fox Sparrows (most to date), Song Sparrows, Lincoln's Sparrows, Swamp Sparrows (most abundant again today), White-throated Sparrows and Dark-eyed Juncos. Sparrows found elsewhere were Field Sparrows (2) and White-crowned Sparrows. Other birds of interest in the area were Pied-billed Grebes, Sandhill Cranes, American Coots (3), a Belted Kingfisher, a Winter Wren, Ruby-crowned Kinglets, Eastern Blues, an Orange-crowned Warbler, a Yellow-rumped Warbler, an Eastern Towhee and a Common Grackle. Dave

Friday, October 27, 2017

The morning started out cold, windy and cloudy; it did not improve from there. The wind was a major factor, especially areas exposed to the north or west. The occasional snowflakes had no effect, except to remind of what was to come. Early thousands of Canada Geese were on Lake Law and A.E. Sea, but soon migrated to the Ag Fields on the north side of the Lab. Other waterfowl found were Cackling Geese, a Snow Goose (Ag Fields, probably the same bird Glenn had on Wed.), Mallards, Gadwall, Northern Shovelers, Green-winged Teal, Ring-necked Ducks (Lake Logo) and Hooded Mergansers. Sparrows found, mostly in small numbers, in the Sparrow Hedge area were American Tree Sparrows, Song Sparrows, Swamp Sparrows, White-throated Sparrows and White-crowned Sparrows. Those found elsewhere were a Lincoln's Sparrow, Fox Sparrows (2) and Dark-eyed Juncos. About 8:15, several hundred Canada Geese flushed from the Ag Fields and returned to the Lakes. Soon after an Adult Bald Eagle showed up from the same direction and circled A.E. Sea, most likely the cause of the concern for the spooked geese. Other highlights in the Sparrow Hedge/Lakes Region were Pied-billed Grebes (2), Sandhill Cranes (3-possibly the family that bred in the Lab this past season), a Wilson's Snipe, a Belted Kingfisher, a Merlin (bird of the day, an especially good year for this species), American Crows, Ruby-crowned Kinglets and a Palm Warbler. Interesting birds found elsewhere in the Lab were a Cooper's Hawk (migrating thru), Killdeer (lots in Ag Fields), an American Kestrel, Horned Larks (lots in Ag Fields), a Nashville Warbler and Yellow-rumped Warblers. Dave

Wednesday, October 25, 2017

Today Glenn made a short stop in the North Roads area of the Lab and among the over 2000 Canada Geese he located 18 Horned Larks and a couple of Eastern Meadowlarks. On Monday, another trip to the Lab produced a Snow Goose in the North Eola Road Ag fields. In addition, Lake Law provided a couple of Mute Swans that eventually flew off to the west. Other highlights of his trip were Wood Ducks (3), a Northern Harrier, an American Crow and Horned Larks (3). Dave

Sunday, October 22, 2017

The morning started quite pleasant with temps in the mid 60's, mild winds and mostly cloudy skies; however, intermittent showers started midmorning then progressed to consistent rain later. In the Lakes region, waterfowl were not much better than Wednesday, but Canada Geese numbers were up another notch. Others found were Cackling Geese, Wood Ducks, American Black Ducks (at different location), Mallards, Northern Shovelers and Green-winged Teal. Sparrows showed some improvement with a couple of Le Conte's Sparrows (one of the birds of the day), Song Sparrows, Lincoln's Sparrows, Swamp Sparrows, White-throated Sparrows and White-crowned Sparrows. Added elsewhere were a Chipping Sparrow, Field Sparrows and a couple of Fox Sparrows. The other bird of the day was an American Bittern that flushed less than 3 feet from me in some tall grass adjacent to Lake Law. Other birds of interest found in the Lakes/Sparrow Hedge Region were Pied-billed Grebes (3-4), Sandhill Cranes (5), a Greater Yellowlegs, a Belted Kingfisher (SW corner of A.E. Sea), a Golden-crowned Kinglet and a Palm Warbler. Some of the birds found elsewhere in the Lab were several Wilson's Snipe, Eastern Phoebes, American Crows, Ruby-crowned Kinglets, Eastern Towhees and an Indigo Bunting. On his way home Peter visited the center of the Main Ring and found an American Coot, a Northern Harrier and an Eastern Meadowlark. Dave

Wednesday, October 18, 2017

The morning started cool, sunny, with a mild wind. It again warmed through the morning, while the winds increased only slightly. Lake Law is now almost back to its pre drawdown level. As a consequence there were no shorebirds found in the Lakes area. There was an influx of the largest group of Canada Geese of the season accompanied by several Cackling Geese. Ducks were at their lowest numbers over the last several weeks; found were Mallards, Northern Shovelers (less than 20), Hooded Mergansers (pr) and Ruddy Ducks (8). Birding other areas of the Lab did not improve this list. One shrub contained Song Sparrows, Swamp Sparrows, White-throated Sparrows and a Lincoln's Sparrow. Also found in the area were a Field Sparrow and a couple of White-crowned Sparrows. The bird of the morning was a Merlin in a dead tree at the south end of A.E. Sea. Other birds of interest in the area were Belted Kingfisher, an Eastern Phoebe (others found elsewhere), Ruby-crowned Kinglets, Eastern Bluebirds (migrating over the area) and Cedar Waxwings. Birds found in other areas were a Cooper's Hawk (probably a resident in the Garden Club), Killdeer, Long-billed Dowitchers (2-in a fuddle along South Eola Rd.), a House Wren, Yellow-rumped Warblers and an Eastern Towhee. Marcia and Gail were also in the Lab this morning spending most of their time in the Main and Injector Ring Areas. They also had Yellow-rumped Warblers in addition to a late Nashville Warbler. Most of their sparrows were White-throated Sparrows and White-crowned Sparrows, but they also found the first American Tree Sparrows of the season. Dave

Monday, October 16, 2017

Glenn made a short stop in the Sparrow Hedge/Lakes Region this evening. Highlights of this trip were Wood Ducks an American Wigeon, Mallards and Ruddy Ducks (11 at Lake Law), Song Sparrows, a Lincoln's Sparrow, Swamp Sparrows, White-throated Sparrows and White-crowned Sparrows. Dave

Sunday, October 15, 2017

Despite the cool temps and the extremely strong NW winds, we had a phenomenal morning of birding. In addition, the heavy rains of Saturday greatly raised the levels of the lakes around the Lab. This wiped out most of the shorebird habitat at Lake Law and all of the habitat at A.E. Sea. As a consequence, shorebirds were at a premium with only a couple each of Killdeer and Greater Yellowlegs. We also added a couple of Wilson's Snipe, but these were flushed in thick marshy areas. Waterfowl were somewhat sparse compared with our last several visits. Those found were Canada Geese, Cackling Geese, Mallards, Gadwall, Wood Ducks, Blue-winged Teal, Northern Shovelers (much small numbers than earlier in the week), Green-winged Teal, a Hooded Merganser and a Ruddy Duck. It was a day for eagles with 3 Bald Eagles (2-Adults and 1-Sub Adult) and a Golden Eagle migrating thru. Because of the strong winds, the sparrows were mostly heard and not seen. Those found were Song Sparrows, a Lincoln's Sparrow, Swamp Sparrows (most numerous species, again), White-throated Sparrows and a White-crowned Sparrow. Other birds found in the Sparrow Hedge/Lakes Region were Turkey Vultures (2-3), Sandhill Cranes (5-west side of L.Law), a Merlin (migrating high), several Ruby-crowned Kinglets and a Palm Warbler. Found in the A.E. Sea Slots along Batavia Rd. were several Great Egrets, Black-crowned Night-Herons (3) and an American Bittern. Interestingly, the skies were filled with Great Egrets most of the morning, seemingly not able to find suitable foraging areas due to the high waters. The bird of the day was also a first for the Lab (new for the Fermi Birdlist) a Laughing Gull. It was in the center of Lake Law early on, but not to be found upon our exit of the area. Lastly, Glenn had a first of the year Harris's Sparrow yesterday (Saturday) east of the Lake Law Berm. Other sparrows he found during the short break in the rain were a Clay-colored Sparrow, a Field Sparrow, a Vesper Sparrow, Song Sparrows (3), Lincoln's Sparrows (3), Swamp Sparrows (9), White-throated Sparrows (10), White-crowned Sparrows and, unfortunately, the first 2 Dark-eyed Juncos of the year. Dave

Wednesday, October 11, 2017

Not a pleasant morning for birding but there were birds to be found. The main birding deterrent were the fairly strong NE winds. The accompanying on and off showers had little effect. American Crows have been quite prevalent over the last month or so. This morning one was seen harassing a Cooper's Hawk as the hawk was trying to catch a shorebird breakfast at Lake Law. Shorebirds that remained were Killdeer, Greater Yellowlegs (3), a Lesser Yellowlegs, a Semipalmated Sandpiper, Pectoral Sandpipers and Long-billed Sandpipers (2). The only new waterfowl for the season found in the Lakes Region were several Gadwall. Other waterfowl found today were American Wigeons, American Black Ducks, Mallards, Northern Shovelers, Northern Pintails and Green-winged Teal. Sparrow numbers were down in the Sparrow Hedge Region, but some other areas of the Lab had larger concentrations. Found today were a Clay-colored Sparrow (in Garden Club), a Field Sparrow (also in Garden Club), Song Sparrows, a Lincoln's Sparrow, Swamp Sparrows, White-throated Sparrows, and White-crowned Sparrows. Other birds found in the Sparrow Hedge area were a Yellow-bellied Sapsucker, Northern Flickers, a Golden-crowned Kinglet, Ruby-crowned Kinglets (a flock of about 20 birds), Eastern Bluebirds and Palm Warblers. Warblers found elsewhere were a Nashville Warbler and several Yellow-rumped Warblers. Roads and Grounds personal had a very interesting sighting this morning of an adult Bald Eagle rearranging nest material at Osprey Nest 2. The eagle was also seen trying to select sticks from a brush pile before being disturbed. They also reported several Sandhill Cranes in the Buffalo Wallow along Road D. The bird of the day was a very boisterous Red-shouldered Hawk heard then seen at the far southeast corner of the Sparrow Hedge area. Dave

Monday, October 9, 2017

Al Stokie was in the Lab today and was able to get both a Le Conte's Sparrow and a Nelson's Sparrow. In addition, he had a flyover Snow Goose(white) and five Long-billed Dowitchers. Dave

Sunday, October 8, 2017

A cloudless sky greeted us this morning. While a little cool to start, it quickly warmed into the mid 70's. The whole morning was spent in the Sparrow Hedge/Lakes Region. The first bird of the morning was an immature Bald Eagle, flying south over Lake Law. Shorebirds at Lake Law were not too impressive, found there were Killdeer (still in good numbers), a Semipalmated Plover, Greater Yellowlegs, Lesser Yellowlegs, Pectoral Sandpipers and a Long-billed Dowitcher. Waterfowl still continue to trickle in. Interestingly, some of the first sightings of these season birds are 2 to 3 weeks behind schedule. I would guess September's abnormally high temps kept the birds up north longer. Found in the Lakes Region were Wood Ducks, American Wigeons, American Black Ducks, Mallards (of course), Blue-winged Teal, Northern Shovelers, Northern Pintail, Green-winged Teal, a Ring-necked Duck, Hooded Mergansers and a Ruddy Duck. Sparrow diversity was down a little. Those found were Le Conte's Sparrow, Nelson's Sparrow, Song Sparrows, Swamp Sparrows (well over half the sparrows found), White-throated Sparrows and White-crowned Sparrows. Other birds found in the area were an American Coot, a Herring Gull, Great Egrets (over 90 at A.E. Sea), Yellow-bellied Sapsuckers (2), a Hairy Woodpecker, American Crows, Marsh Wrens (quite active in some areas), Eastern Bluebirds, a Swainson's Thrush, a very late Yellow Warbler (latest ever at the Lab) and a Palm Warbler. Dave

Thursday, October 5, 2017

Al Stokie was in again this morning and had the first White-fronted Geese (6) of the season fly in and land right in front of him at Lake Law. The only shorebirds found were Killdeer and Pectoral Sandpipers (26). Other birds of interest were Wood Ducks, Blue-winged Teal, Northern Shovelers, Green-winged Teal, Pied-billed Grebes (2), Sandhill Cranes, Eastern Phoebes (2), Barn Swallows (2), American Pipits (2) and Swamp Sparrows. Dave

Sunday, October 1, 2017

I have only partial reports from the Sunday birding by Peter and Denis. It appears sparrows are now migrating thru the Lab with good variety. Of the 8 species found, Le Conte's Sparrows and Nelson's Sparrows were the highlights. Others reported were Savannah Sparrows, Song Sparrows, Lincoln's Sparrows, Swamp Sparrows, White-throated Sparrows and White-crowned Sparrows. Other birds mentioned were a Ruby-crowned Hummingbird, a Sandhill Crane, a Bald Eagle, a Cooper's Hawk, a Ruby-crowned Kinglet, a Tennessee Warbler and a Magnolia Warbler. Dave

Tuesday, September 26, 2017

Al Stokie was in on Tuesday and came up with several very good birds in the Lake Law area. The best of these were an American Golden Plover and a Merlin chasing some shorebirds. Other birds of interest were a Semipalmated Sandpiper, Baird's Sandpipers (2 together), still a good number of Pectoral Sandpipers (22), a Juv Stilt Sandpiper, an Eastern Phoebe, American Crows and an American Pipit. Dave

Wednesday, September 27, 2017

The morning was mostly cloudy and in the 60's with moderate winds. At Lake Law, the number of Pectoral Sandpipers was almost equal to the number of Killdeer (although Killdeer numbers were down from that of the past few weeks). The only other shorebirds of interest were a Greater Yellowlegs and a Stilt Sandpiper. Other birds found in the Sparrow Hedge/Lakes Region were Pied-billed Grebes (4), American Coots (2), a Green Heron, a Bald Eagle, a Cooper's Hawk, an Eastern Wood-Pewee, an Eastern Phoebe, a Warbling Vireo, American Crows (2-3), Marsh Wrens, a Ruby-crowned Kinglet (a season first), a Brown Thrasher, Cedar Waxwings (again mostly Juv's), an American Redstart (only warbler, except for yellowthroats), Eastern Towhees, Lincoln's Sparrows (3), White-throated Sparrows and Rose-breasted Grosbeaks. The Great Egrets were again in DUSAF Pond (60 plus). Found elsewhere in the Lab were an American Kestrel, Hairy Woodpeckers, a Blue-headed Vireo (1st of the year, eating a large grub), Eastern Bluebirds, a Swainson's Thrush, Black-throated Green Warbler and a Fox Sparrow. Dave

Sunday, September 24, 2017

Again the morning started comfortably in the 70's but reached into the upper 80's by our departure. The mild winds had no effect on the birds nor provided any cooling for us. Lake Law continues to produce a nice collection of shorebirds. Found today were Killdeer, Greater Yellowlegs, Lesser Yellowlegs, Semipalmated Sandpipers, a White-rumped Sandpiper, a Baird's Sandpiper, Pectoral Sandpipers, and a Stilt Sandpiper. A nice collection of interesting birds were found in the Sparrow Hedge/Lakes region including Northern Shovelers, Green-winged Teal, Pied-billed Grebes (4-A.E Sea), Sandhill Cranes (1-2 heard near A.E.Sea), Great Egrets (60 plus in A.E. Sea), a Great Horned Owl, a Philadelphia Vireo, Marsh Wrens, a Swainson's Thrush, a Brown Thrasher, Cedar Waxwings, Magnolia Warblers, a Palm Warbler, American Redstarts, Common Yellowthroats, White-throated Sparrows and a Rose-breasted Grosbeak. Main Ring Woods produced a Warbling Vireo, Eastern Bluebirds, a Yellow-rumped Warbler, Black-throated Green Warblers (2), a Bay-breasted Warbler and two new sparrow migrants, a Lincoln's Sparrow and a White-crowned Warbler. Denis' group stayed in the Sparrow Hedge/Lakes region finding many of the same birds as Peter and myself. In addition, they found Black-crowned Night-Herons (3) and some migrant hawks. Included were a couple of Bald Eagles (an adult and a juvenile, probably not migrants), a high flying Northern Harrier, Cooper's Hawks (3) and the bird of the day, a Merlin which put on an aerial display first disrupting the Lake Law shorebirds then swooping down an a passerine. Dave

Thursday, September 21, 2017

Al Stokie was in the Lab this morning, specifically at Lake Law. He added a Semipalmated Plover for the week and had most of the same shorebirds we had on Sunday including Killdeer (28), a Greater Yellowlegs, Lesser Yellowlegs (6), a Solitary Sandpiper, a Least Sandpiper, Semipalmated Sandpipers (3-4), a Baird's Sandpiper, White-rumped Sandpipers (2), Pectoral Sandpipers (13) and a Wilson's Sandpiper. Peter was also birding with a visiting scientist and found many of the same shorebirds. In addition, he noted shorebirds are now starting to show up on the lowered A.E. Sea. They also found the best variety of warblers in the Sparrow Hedge area of the season including Tennessee Warblers, an Orange-crowned Warbler, Nashville Warblers, a Magnolia Warbler, a Black-throated Green Warbler, American Redstarts and Common Yellowthroats. In addition, they found the first confirmed migrating blackbird of the season, a Rusty Blackbird. Dave

Wednesday, September 20, 2017

The morning started comfortably in the mid 60's and sunny, but the temps rose to the mid 80's by noon. The A.E. Slits were barren except for a couple of Green Herons and some Marsh Wrens. There was not a lot of variety on the Lake law flats. Found there were Killdeer, Semipalmated Sandpipers, Pectoral Sandpipers and a couple of Wilson's Snipe. I heard, then watched a Belted Kingfisher fishing from a dead tree at the SW corner of A.E. Sea. Lighting was great. Four or five warblers flew by, but the only one that stopped was a Black-throated Green Warbler. Other birds of note in the Lakes/Sparrow Hedge Region were Wood Ducks, Green-winged Teal, Pied-billed Grebes (at least 3), an American Crow, Eastern Bluebirds, Cedar Waxwings (mostly juveniles) and Indigo Buntings. It appears that the new hot spot for Great Egrets is DUSAF Pond with over 40 being found there. A large flock of House Sparrows was chased by a Cooper's Hawk in the Garden Club. Unfortunately, he missed his breakfast. Migrants found in the Big Woods or Main Ring Woods were a Yellow-throated Vireo, a Tennessee Warbler, Nashville Warblers (5-6), a Blackpoll Warbler, American Redstarts (2) and probably the first sparrow migrants of the season, couple of White-throated Sparrows. Marcia and Gail were also in doing their weekly survey. Their highlights included Wood Ducks, an American Kestrel, an Eastern Phoebe, Cedar Waxwings (11), a Tennessee Warbler, a Nashville Warbler, a Rose-breasted Grosbeak and a Common Grackle. The girls also came up with the bird of the day, a Northern Harrier (first sighting since May) searching a prairie in the Main Injector area. Dave

Sunday, September 17, 2017

The morning started comfortably cool with partly sunny skies but soon warmed into the 70's. The A.E. Sea Slots were barren except for a single Great Blue Heron. A.E. sea's receding waters have removed any standing water in that area. The Lake Law Flats did produce some interesting shorebirds including Killdeer, Spotted Sandpipers, a Solitary Sandpiper, Greater Yellowlegs (2), Lesser Yellowlegs (2), Semipalmated Sandpipers, a Least Sandpiper, a White-rumped Sandpiper (bird of the day and first of the year), a Baird's Sandpiper, Pectoral Sandpipers and Wilson's Snipers (2). Great Egrets were noticeable in that their numbers were the lowest in many weeks (only 4-5 today). Other interesting birds found in the Lakes/Sparrow Hedge region were Wood Ducks (15-20), Green-winged Teal, Pied-billed Grebes (3 Juv), a Ruby-throated Hummingbird, a Great Horned Owl, an Eastern Wood-Pewee, American Crows (several here and other areas of the Lab), a Swainson's Thrush, Cedar Waxwings, a Swamp Sparrow and a couple of Rose-breasted Grosbeaks. We found 7 warbler species. The only one with multiple numbers were the Common Yellowthroats. Others found were a Palm Warbler (Sparrow Hedge), a Tennessee Warbler, a Nashville Warbler, a Black-throated Green Warbler, an American Redstart and an Ovenbird - all in Main Ring Woods. Peter also reported a Common Nighthawk during the week. Dave

Thursday, September 14, 2017

Marcia's and Gail's first stop this morning was again at the Cattail Slots at the south end of A.E. Sea. There they found 9 Soras, Green Herons (3) and Pied-billed Grebes (3). An Osprey was again found in the Betz Prairie area in the same tree as last week. They found the first Palm Warblers (2) of the season, unfortunately, we have not had many other warblers to precede them. What will our next warbler be, a Yellow-rumped Warbler? Other birds of interest they spotted during their morning survey were a pair of Wood Ducks, a Cooper's Hawk, Northern Flickers (4), Eastern Phoebes (3), Sedge Wrens (3), a Savannah Sparrow, Song Sparrows, a Swamp Sparrow, a Rose-breasted Grosbeak and Indigo Buntings.

It was a very nice early fall morning for birding. Temps started in the high 40's and was approaching the 60's by the time we were finished, with mostly sunny skies and a mild breeze. The area around the A.E. Sea "slots" produced Pied-billed Grebes (3-Juv), Soras (around 10), Green Herons and Marsh Wrens. Again Lake Law produced a modest population of shorebirds including Killdeer, Spotted Sandpipers, a Greater Yellowlegs, a Lesser Yellowlegs and Pectoral Sandpipers. Also, Peter spotted an American Pipit on the far west side of the lake. Some early waterfowl movement was evident with Wood Ducks, both Blue-winged Teal and Green-winged Teal and Northern Shovelers on the Sea of evanescence. A nice variety of other birds were found in Lakes/Sparrow Hedge region including Pied-billed Grebes (3-Adults), Chimney Swifts, an American Coot, Great Egrets (42-Sea of Evanescence) Black-crowned Night-Herons (2-Juv south end A.E. Sea), a Cooper's Hawk, a Belted Kingfisher, a Willow Flycatcher, an American Crow, Eastern Bluebirds, a Swainson's Thrush and Rose-breasted Grosbeaks. The only other bird of mention outside these areas was a Brown Thrasher. No migrant warblers were found during the morning. Dave

Altering their usual monitoring protocol this morning, Marcia and Gail started out at the Cattail Slots in A.E. Sea along Batavia Rd. They did get some views of a single Least Bittern in addition to several Soras (5) and Green Herons (3). After checking out several other locations, they returned to their usual monitoring of the Main and Injector Ring areas. Birds of interest found in these other areas were a Pied-billed Grebe, a Downy Woodpecker (needed for the week), an American Kestrel, Eastern Phoebes (3), a Horned Lark, Field Sparrows (2-not as noticeable in expected locations), a Savannah Sparrow, a Rose-breasted Grosbeak and an Indigo Bunting. Also, they reported not finding an Osprey during their travels around the Lab this morning. Dave

The morning started cool (low 50's) and mostly sunny but warmed quickly into the 70's. I missed finding any Least Bitterns in the A.E. Sea slot cuts but, good numbers Soras and Green Herons were still in the area. Shorebirds around Lake Law were still in smaller numbers than last week. Shorebirds found there were a Semipalmated Plover, Killdeer (still quite a few), Spotted Sandpipers, a Greater Yellowlegs, a Lesser Yellowlegs, Semipalmated Sandpipers and Pectoral Sandpipers. These birds were moving around quite a bit and many were out of the range of my scope most of the time. The majority of Great Egrets appear to have moved back to the Sea of Evanescence (numbers early in the morning - Lake Law- 3, Sea of E.-at least 27). Also at the Sea of E., I watched a Great Blue Heron carry around a good sized Bullhead (about 10") for about 5 min. The fish was repositioned regularly while the heron appeared to look for a solid surface to dispatch it. Suddenly, the fish wiggled free and fell into a weedy area where the heron could not locate it but still spent several minutes picking at the weeds ,in an unsuccessful in search. Other birds of interest found in the Lakes/Sparrow Hedge region were Wood Ducks, Blue-winged Teal, a Cooper's Hawk, Bell's Vireos (2), Cedar Waxwings, a Tennessee Warbler, a Nashville Warbler and a Bay-breasted Warbler. Birds found in other areas of the Lab were a Ruby-throated Hummingbird, a Swainson's Thrush, an American Redstart, a Mourning Warbler (bird of the day), a Field Sparrow and a Rose-breasted Grosbeak. The Ruby-throated Hummingbird chased a House Wren into a thick, dead shrub where it continued to harass it until the wren found a secure location. The hummingbird perched nearby and when the wren flushed the hummingbird was again hot on its tail. Dave

The 50 degree temperatures this morning were accentuated by the breezy conditions. The test slots along Batavia Rd at A.E. Sea produced most of the same birds found there in the recent past including Pied-billed Grebes (2-Juv), Soras (at least 10), Least Bitterns (2) and Green Herons. By the way, these test slots are an experiment to try and reduce the cattail density around A.E. Sea. The shorebirds at drawn-down Lake Law were a little disappointing this morning both in quality and quantity. Killdeer were most numerous with 50-75 spread around the lake. Others found were several Spotted Sandpipers, a Greater Yellowlegs, a Semipalmated Sandpiper and a Least Sandpiper. Another small flock was spotted but left the area before the birds could be identified. There was a good number of swallows over the Sea of Evanescence including Tree Swallows, Northern Rough-winged Swallows, Barn Swallows and several Chimney Swifts. Other birds of interest in the Lakes/Sparrow Hedge Region were Wood Ducks, Double-crested Cormorants (about 100 in the SW corner of A.E. Sea), a Bell's Vireo, a Sedge Wren, Marsh Wrens, Eastern Bluebirds and Cedar Waxwings. An interesting incident occurred in the Osprey Nest 1 area. An adult Osprey was on the power pole next to the nest pole when a Red-tailed Hawk landed one pole down from the Osprey. The Osprey took off and buzzed the Red-Tail until it flushed. The Osprey then chased it out of the area. Later the Osprey, now perched on the Nest 1 pole, got quite irritated when a Turkey Vulture glided over the nest pole. The positive from these incidents is that there still appears to be loyalty to the area by this Osprey. Some of the other highlight birds found elsewhere in the Lab were Turkey Vultures, Hairy Woodpeckers, American Kestrels (5), a Least Flycatcher, a Great Crested Flycatcher and Indigo Buntings. Finally, the bird of the morning was an early Merlin perched out in the open, flushing then flying south. Dave

Marcia and Gail were in doing their usual midweek bird survey in the Main and Injector Rings. Again they came up with another new migrant warbler for the fall season - a Tennessee Warbler (actually 3). They also spotted 4 of this year's Ospreys in their survey areas. It's good to know there are still some of these birds around the Lab. Other highlights of their morning's birding were a Pied-billed Grebe, Green Herons (still well dispersed around the Lab), an Eastern Kingbird, Red-eyed Vireo, Sedge Wrens (2), an Eastern Bluebird, Cedar Waxwings, and a Chipping Sparrow.
