powell 1949 aphelocoma coerulescens 1. May 7 San Joaquin Experimental Range, 1000' alt., SSW of O'Neals, Madera Co., Calif. Several pairs in vicinity of headquarters. A nest was discovered in olive tree in courtyard of building where most of the men in class slept last night. The birds were quiet gong coming -- until some of us climbed the tree to inspect the nest and even then their scolding was mild. The nest was about 15 ft. up, in crotch of branches 1 to 3" thick, in rather open spot for Jay's nest. It held 1 nestling in bursting pinfeathers and (according to Bruce Brown) 2 eggs as well. Dr. Pitelka thinks the 2 sterile eggs a small clutch of 3 total may be due to low fertility in 1st year 4.
