Cowgell 1950 Vireo gilvus 3 June 28 (cont'd) veered about erratically, and a moment later Dr. Joel Gustafson, who occupies the 3rd floor room at the E. end called to me a gave me the 2 birds which had crashed into the glass pane of the door of his room facing the porch. Both were dead, having apparently flown into the glass be- cause of reflection of the outside view therein. I prepared one (my cat. # 147), which proved to be a ♂, and Geo. Treichel did the other, which was a ♀. There are still 3+ other singing ♂'s in or near willow thickets of the 20+-acre "Cowgell meadow" near the lodge. June 29. Bird on nest described on June 17.
