This week, 92 species were recorded on campus. Most of the new arrivals and good numbers occurred early in the week. By week's end, diversity and abundance were petering out, with only 46 species and under 300 individuals being recorded today (versus 73 species and nearly 700 individuals on 2 May). So most of the early-season migrants have moved out, and the mid-season wave has not yet arrived.
Some notable species were a flyover Common Loon on 4 May and a Summer Tanager on 3 May. The Red-headed Woodpecker was last seen on 30 April, and the Prothonotary Warbler on 2 May.
