***Mega; First recorded??? Apparent female hybrid picked up with 3 Pine Warblers just off the parking lot in response to pishing. At my first brief glance I called it a Blue-winged, but after a point blank look I was thoroughly confused. The bird had a rich yellow breast contrasting with striking white undertail coverts, noticeable white-flashes in the tail (which it fanned several times), a faint black line through the eye, which to me is a perfect Prairie eye-line, yellow eye-ring (unlike blue-winged), blue wings with two faint to non-existant dull yellow wing bars, a greenish olive back and crown. The olive crown is contrasted by a yellow slice above eye and bill, and the auricular region is also olive, in contrast with a bright yellow throat.. Marshall Iliff refound this bird a week later and observed it building a nest and appeared to be being watched over by a male Prairie. Myself and Jeff Offermann returned after that and refound it once more. Upon approaching the nest location, a male Prairie burst from just off the ground and began flying around us aggressively. Shortly after the apparent Prairie x Blue-winged came out from the exact same location, and we realized we had incidentally flushed it off its nest, which contained 3 eggs. We backed up, and the hybrid warbler came back down onto the nest.;
