A flock of about a dozen Cattle Egrets was seen in the Swenson Rd. horse paddock today.

Sunday, April 26

Another good day of birding at Fermi despite some soaking rains. A late female Northern Pintail was along Swensons Road along with Northern Shovelers, Blue-winged Teal, Lesser Yellowlegs and Greater Yellowlegs. The fields west of Lake Law produced an Osprey, Peregrine Falcon, and some Henslow's Sparrows. Other sparrows seen throughout the Lab were White-crowned Sparrows, White-throated Sparrows, Chipping Sparrows, Vesper Sparrows, a Savannah Sparrow, and lots of both Swamp Sparrows and Field Sparrows. Other highlights seen today were Solitary Sandpipers, Spotted Sandpipers, a Least Flycatcher, a Warbling Vireo, a Marsh Wren, an Eastern Bluebird, Ruby-crowned Kinglets, a Palm Warbler, and a Yellow Warbler.

Evening birding at the lab produced several birds of interest. The Woods inside the ring produced the following birds American Woodcock, Blue Jay, Golden-crowned Kinglet, Ruby-crowned Kinglet, Blue-gray Gnatcatcher, Yellow-rumped Warbler, Eastern Towhee, White-throated Sparrow and White-crowned Sparrow. Various ponds of the lab produced Blue-winged Teal, Green-winged Teal, Northern Shoveler and Solitary Sandpiper. Finally, I had a response from an Eastern Screech-Owl. Dave

Other than a few showers the weather conditions were great as was the birding at Fermi this morning. A good number of early migrants were in the woods, along with three late Common Loons on Lake Law. One highlight was a five swallow morning with Tree Swallows and Barn Swallows everywhere, Cliff Swallows and a Bank Swallow over Main Ring Lake and Northern Rough-winged Swallows over Lake Logo. On Osprey was sighted in the Main Injector Ring along with a Great Egret, Ring-necked Duck, Brown Thrasher, Field Sparrow, Savannah Sparrow and a pair of Wood Ducks cavorting in the top of a tall tree. The Center Ring Woods was hopping with migrants including loads of White-crowned Sparrows, White-throated Sparrows, and Yellow-rumped Warblers; many Eastern Towhees and Hermit Thrushes; and a Ruby-crowned Kinglet. Not many birds were seen in the Big Woods but, two surprises were a Northern Waterthrush and Pine Warbler along with many Yellow-rumped Warblers and a Blue-gray Gnatcatcher. Other birds of note were several Wilson's Snipes, Horned Larks, a Ruddy Duck, several Northern Shovelers and a pair of Great Horned Owls. Dave

Sunday, April 12

Only one of the American White Pelicans remained on site this morning. It was on Main Ring Lake but was seen later in the morning circling in a thermal over the center of the ring. There was little else to be seen in the way of migrant waterfowl; a Horned Grebe on Lake Law, some Ruddy Ducks on Main Ring Lake, Common Mergansers, Hooded Mergansers, and Lesser Scaup on A.E.Sea, and Northern Shovelers, Blue-winged Teal, Green-winged Teal, American Black Ducks, and Buffleheads on the smaller ponds. There were also a number of new arrivals today; Black-crowned Night-Heron, Brown Thrasher, Barn Swallow, and Northern Rough-winged Swallow.

Wednesday, April 8

The American White Pelicans are still present on site in large numbers. This morning they were evenly divided between Lake Logo and A.E.Sea with just one bird on Main Ring Lake.

Sunday, April 5

Despite chilly winds, we had an excellent morning of birding on site. The best bird of the day was a female White-winged Scoter on Main Ring Lake (3rd site record). Not far behind in rarity, was a Franklin's Gull that was also seen at Main Ring Lake. The American White Pelicans were also still there, though most of the flock had moved to Lake Logo. Adding to the excitement, was a flock of seven Horned Grebes on Lake Law; all in advanced stages of moult. Rusty Blackbirds were seen at several locations again today and there were a number of new arrivals including Yellow-bellied Sapsuckers, Hermit Thrushes, Ruby-crowned Kinglets, Savannah Sparrows, and a Swamp Sparrow.

Friday, April 3

About a hundred of the American White Pelicans were still on site this morning. However, they have moved from A.E.Sea where only one remained, to main ring lake. There were also several Redheads on Lake Law this morning, and there was a Common Loon on A.E.Sea yesterday.

Wednesday, April 1

There was a large flock (50-60 birds) of American White Pelicans feeding on A.E.Sea this morning and last night there were 18 on Lake Law. By the evening however, the number of birds on A.E.Sea had risen to around 200. This is our first Spring record for this species and the first site record since 2003.
