 5 THE CONI)OR Vol. II ground and lost. In a pine tree forty feet from the ground; April 8, 'tS7S, nest and tvo eggs with large embryos. In a pine sixteen feet from the ground. All the nests were at an altitude of from 5,000 to 5,500 feet. Ten years later Mr. Denis (ale of (old Hill, Boulder Co., Colorado found a nest on March 5, 888 in a scrubby pine eight feet high containing three eggs. On April 6, t889 he found another uest and three eggs in a pine nine feet high s. pecmen of the bird which I used to shoxv prospective collectors as a sort of object lesson. Imn indebted to Miss Jean Bell of Pennsylvania for specific and intelligent notes on the life history of Clarke's Crow which definitely fixed the breeding time for Utah in a mild year, and ultimately led to the taking of the nests and eggs. The several expeditions which I have sent out have met with the varying re- suits detailed below. The Olsen- I'hoto kv It' f1. Park'r. NEST AND EGGS OF C I.

Goss' found nests xvith young in Colorado in 879, but the only nests and eggs recorded up to this year were the four already mentioned. I have been trying to obtain nests and eggs of this'species for several years and with this end in viexv, have secured the services of various intelli- gent campers and miners who are at home in the hills. I had a mounted Ambrose expedition to the Tintic Range during the third week in March g99, reported birds mated. Two were shot, but only one secured,--a fenrole in full breeding plumage. One old nest was found in a black balsam tree on a hori- zontal limb three feet front the trunk, and was supposed to be of this species. One bird xvas observed chasing a (old- en Eagle in a manner similar to that of blackbirds worrying a passing hawk. The Anti)rose-Olsen-Johnson expedition
