Second-year Male Myrtle Warbler

Normally, the first warbler of the season would be the lede story, but the handsome male Myrtle Warbler unfortunately had to play second fiddle to a much more unusual capture.  Midway through the morning, Marian noticed that the junco in her hand had strong white wing bars and white fringing on the uppertail coverts.  Almost all of the juncos in the Rochester area are of the Slate-colored subspecies of Dark-eyed Junco, but there is a related subspecies from the Black Hills area of the midwest known as the White-winged Junco.  For most of the morning, we were convinced our visitor was a vagrant White-winged Junco, but after doing some research we discovered that some Slate-colored Juncos can also apparently have white wing bars.  So which variety did we have?  The jury is still out, and the experts are weighing in!  For now, we’ve just recorded it as a Dark-eyed Junco.
