Today was my first day back on site after a month long vacation in Papua New Guinea and I was pleased to see that waterfowl migrants are starting to come through. A couple of Northern Pintail were on a pond north of the bison feeders and Northern Shovelers found at several locations. The warbler migration is clearly tailing off, though we did manage to find a Northern Waterthrush, a Tennessee Warbler, and a Blue-headed Vireo among the many Yellow-rumped Warblers inside the main ring. The best bird of the day was an Osprey that apparently has been frequenting Casey's and Andy's ponds and perching in the dead trees along Eola rd.

Another very pleasant morning at Fermi produced the following birds in the Sparrow Hedge area: Yellow-bellied Sapsucker, Marsh Wren, Sedge Wren, Eastern Phoebe, Warbling Vireo, Red-eyed Vireo, Swainson's Thrush, Blackpoll Warbler, American Redstart, Eastern Towhee, Rose- breasted Grosbeak, Swamp Sparrow and White-throated Sparrow. Seen in the flooded buffalo fields were Pied- billed Grebe, Pectoral Sandpiper, and over thirty Wilson's Snipe. An Osprey was seen perched on a tall dead tree near the northeast corner of Batavia and Eola roads, believe it or not I have seen Osprey's on this same snag several times over the last few years. This may have been the same bird seen by Rod on Friday. Some other birds of interest seen this morning were Magnolia Warbler, Tennessee Warbler, Indigo Bunting and Field Sparrow.

Some evening birding today and yesterday produced little of interest and less in the line of owls. Owling was done on Friday with no responses; it may have been the deafening sound of the tree frogs??? Thursday evening produced Black-crowned Night-Herons and a Belted Kingfisher on DUSAF Pond. Other birds of note were American Coots, Common Nighthawks and a good number of Wood Ducks on Main Ring Lake. On the way out of the Lab on Thursday I noticed the flooded buffalo fields, so that was where I went before owling on Friday. I found a Black-bellied Plover and both Lesser Yellowlegs and Greater Yellowlegs in the flooded field. Unfortunately, it was getting dark and it's probable that more birds were foraging in the grasses. Also, Friday morning produced an Osprey over Casey's Pond for Rod Walton. Dave

Birding was very good early this morning with several small mixed flocks of migrants in the scrub of the Sparrow Hedge area. These flocks included Nashville Warblers, Tennessee Warblers, American Redstarts, a Wilson's Warbler, a Yellow-throated Vireo and a Swainson's Thrush. Other birds seen in the area were a Cooper's Hawk, a Ruby-throated Hummingbird, a Brown Thrasher and a Baltimore Oriole. Things were fairly quiet in most other areas of the lab until just before I was ready to leave. In one of the small wood lots in the North Roads area I encountered a huge flock of warblers, consisting of approx. fifty birds. This was the largest I had seen in quite awhile, it included all of the earlier warbler species plus several Black-and-white Warblers, a Magnolia Warbler, a Cape May Warbler, and the best bird of the day a Blue-winged Warbler. Other birds of note in the Lab were Horned Lark, Indigo Bunting, American Coot, and
