Screech Owl Egg in Crow's Nest
Screech Owl Egg in Crows ’ Nest.--In the course of a field trip near Fullerton, California, on April 22, 1945, I was much surprised to find a Screech Owl (O& asio) egg in a set of four American Crow (Corvus bra&rhynchos) eggs. A crow was incubating the eggs at the time of discovery and all eggs showed evidence of fertility. The owl egg was compared with several sets of the species in my collection and corresponded closely in size and shape. The nest tree showed no signs of having been climbed prior to my ascent.-EDWARD M. HALL, Whittier, California, January 15, 1947.
