Wisconsin Statewide Birding Report 7.22.10
Late July brings the first influx of migrant passerines and shorebirds. A few birders have been reporting Tennessee warblers, Nashville warblers and other species moving around now that their breeding season is almost over. Most of these species will molt and make their way into central and south America. Water levels are fairly high, but birders that have found exposed mudflats are finding least sandpiper, lesser yellowlegs and a few other early shorebird migrants. The nesting season is just winding down but some species are now working on late nests or their second or third clutches. Rare birds reported this week include a couple of rufous hummingbirds, and there has been breeding success in a colony of black-necked stilts at Horicon National Wildlife Refuge.
