Paris 9-46 15. 6 mi. N of Lachuca, 9600 ft, Hidalgo, Mex. July 1, 1946 small fir, about 15 ft from the ground. A Junco phaeonotus was collected while it was foraging about 30 ft up in a large fir at the edge of a clearing. A small Empidonax (difficult?) was taken from its perch about 10 ft from the ground in a tall fir at the edge of a road. 2 Red Warblers responded to Pygmy Owl calls, but remained from 30-60 feet up in the firs, moving so actively that I could not get a shot at them. Their call-note was a sharp "tzip," much like that of an Audubon War- bler. Ate lunch & skinned in p.m. Started to hunt at about 4:30 p.m. but it started rai- ing at about 5:00 and I returned to camp. July 2, 1946 Hunted from 6:30 to 10:00 a.m. About 1/2 mile NW of camp found a large woodland clearing with numerous patches of red Lentiskmon. The clearing was alive with Colibri thalassinus, and one was collected as it hovered in the air while feeding on the Lentiskmon. These large hummingers are often seen perched in the firs, sometimes choosing perches 25 and 30 feet above the ground. They are one of the most abundant birds of the region, being scattered along trails and roads, and reaching their maximum numbers in woodland clearings. The sharp "t-click" note
