A crisp and cool night following a home football game made for lots of birds on the move and, evidently, quite a few coming into campus. I found this morning 3 dead Lincoln’s Sparrows: southwest alcove, southwest peninsula, and southern portico. I found a dead Grasshopper Sparrow at the northwest alcove.
Trapped birds consisted of a Song Sparrow that I pushed away from the southwest alcove, and a Chipping Sparrow in the rafters of the southern portico, apparently unable to figure out that flying down was the key to getting out.
