First off, my yard in west Ames has been surprisingly productive. So far I've had 11 warbler species:
Tennessee Warbler
Nashville Warbler
Yellow Warbler
Chestnut-sided Warbler
"Bay-poll" Warbler
Black-and-white Warbler
American Redstart
Northern Waterthrush
Mourning Warbler
Wilson's Warbler
Canada Warbler
Three other warblers that I haven't had in the yard yet but DID see this morning in Ames included:
Blackburnian
Golden-winged Warbler
Ovenbird
The yard has also produced these other migrants:
Least Flycatcher
"Traill's" Flycatcher
Eastern Wood-Pewee
Veery
Swainson's Thrush
Pretty fun time to bird central Iowa! Or maybe I'm just overexcited to see "eastern" warblers (considering I don't see too many during my field work in Nebraska).
