American Wigeon (click to see the larger version)

May 19 will go down as the best day for migration in 2023. Montrose was full of warblers, thrushes, and flycatchers. It was also full of birders. Over 140 species were reported to eBird by all observers, and several people topped 100, which only happens a couple times each year. My highlights include

American Wigeon (late)
Yellow-billed Cuckoo
Ruddy Turnstone (4)
Common Tern
Olive-sided Flycatcher
Yellow-bellied Flycatcher
Alder Flycatcher
Golden-winged Warbler
Prothonotary Warbler
Black-throated Blue Warbler
Mourning Warbler (6!)
Hooded Warbler
Summer Tanager
Dickcissel

Migration will start to wind down, but late May is still an excellent time for later warblers and vireos, and flycatchers will continue to increase through the end of the month.
