They were first noticed about noon of the 26th, by a Mr. Dufferik, and were then feeding on pinyon nuts. Some of the birds were on the ground, searching for the fallen nuts. Their confiding nature, and the fact that they roosted in the trees nearby, enabled Mr. Dufferik to capture one alive, a bird of the year,

For instance, ring counts have provided some information on the effects of fire and other disturbances on the pinyon-juniper type in Arizona (Arnold, Jameson, and Reid, 1964).
