May 5th – New Species Continue to Arrive

First Black & White Warbler of the year: an ASY male.

The cool NE wind and cloud through the night likely restricted migrant movement or, at least, reduced the flight distance during the night. Always a good thing for us as birds “drop in” rather than fly on by/over. Whatever the dynamics we had a pretty interesting day, banding 69 birds and encountering 61 species – 6 of these were new for the year: Ruby-throated Hummingbird, Wood Thrush, Yellow-throated Vireo, Black-throated Blue Warbler, Black and White Warbler, and Common Yellowthroat.

In the last couple of days Ruthven has been transformed by the influx of migrants. Rose-breasted Grosbeaks and orioles (both Baltimore and Orchard) and a variety of warblers/sparrows are calling, starting at the crack of dawn and the grosbeaks and orioles are flying all over the site, frantically trying to establish territories before the females arrive.

Not only are Rose-breasted Grosbeaks aggressive, they have the beak to back themselves up. Ouch!!
