Pitella 1946 88 Cyanocorax dickeyi Oct. 18 El Batel, 70 km. NE Mazatlán, 5100ft., Jinaloa. Met a loose flock of 10-12 individuals along a ridge south of the pass in a rough, steep-sloped draw where the pines and oaks were fairly large, compared to the second-growth along the road below. They were moving toward me when I first saw them, and my presence did not appear to disturb them. They continued past me and continued along a ridge and then dropped into the forest again. In all I spent almost an hour with them; one was collected at the very end of my observation period when they were dropping down the steep slope. The flock drifted along very leisurely, spreading over an area about 50 feet wide and 75 feet long. Most of the time, the individuals fed, but some perched quietly, others hopped about limbs with seeming aimlessness. Feeding occurred on the ground, or prominent points such as rock outcrops near tree foliage, as well as in the upper leafy branches of pines and oaks; but most of the feeding occurred along the main, lower branches of oaks covered with dense growth of lichens, moss, and epiphytes. About each mass of plant growth, the individual jay would pause, examining it from all sides and poking into it. Once one pounded a fragment in the same manner that Aphelocoma pounds nuts. Leopold also observed the pounding action.
