Nov., I9o 7 SUMMER NOTES FROM AN ARIZONA CAMP I97 1906, when Mr. F. E. Trask, City Marshall of Benson, secured five birds near Lone Mountain, between the altitudes above indicated. (2. m. mearnsi is quite in evidence--at times. The first young I met with was on August 6. They must be very irregular breeders, for even now, in the latter half of August the adult birds are still to be seen in pairs. Acorns or mast and ladybeetles, is the prevailing fare hereabouts. The Scaled Partridge sticks to the Mexican Poppy (Ar?emone mex- icana) almost entirely at this season. While the Gambel Partridge haunts the canyons where certain crossworts (Crucifers) grow. I was surprised to find the Elf Owl (fUicropallas whitney[) so abundant, and up to 5000 feet, too. They furnish a good share of the night sounds here. On a moonlight evening you may observe them, little flocks of five or ten, often in a single tree. Moths (which during June were very numerous) form a substantial food supply. They catch the moths much in the manner of a flycatcher, returning to their original perch. One bird I shot had an immense sphinx, almost the wing dimension of the bird, in his bill. They also secure quantities of Longicornes (beetles), but I have found no evidence of their preying on birds. About camp we have twenty White-winged Doves(Jl/?eloISelia leucoIStera)to one Mourning Dove. The former species is another bird very fond of Argemone seed and its distribution is no doubt affected by it. The Coues Flycatcher ( Conlopus perlinax palh'divenlris) is very rare in these mountains, atleast this year. I secured a bird of this species in the Rio San Pedro valley on April 18, last.
