[cobirds] possible Yellow-bellied Flycatcher, CU-Boulder campus

At approximately 2:45 this afternoon, while in my office on the phone I noticed a small dark bird flycatching in a barren honey-locust about 40 feet outside my office windows on the south side of Regent Administrative Center (Broadway and Regent Drive in Boulder).  After a few forays, the bird headed east along the building out of my window view.   At the end of my call, I decided to wander outside to see if I could refind the bird.  In order to head out of the building to my car for binoculars, I stepped outside the 2nd story door onto a stairway balcony at the front of the building, and there was the bird again perched on the railing less than ten feet away.  I was able to study the bird as it turned in a variety of positions and studied me for 30 to 60 seconds before it flew off.  I have not been able to see it again.

 

Here is my description:

 

Flycatcher:  bright greenish yellow; yellowish chest as well as head and back; round head; small bill (with darker upper mandible); bright white wing-bars on black wings with top one ½ the length of the bottom one; wings showing white edges on the secondaries; round buffy-white eye-ring; white outside edges on the tail, seemingly short primary projections.

 

I will continue to keep an eye out, of course.  If you would like to try to bird in this area, there is pay parking nearby and the campus probably won’t be very busy tomorrow.
