P. PEARSON 1951-1952 Hummingbird Dec 7 Rio Torota, 11,200 ft.; 15 km N.E. Torota, Maguayana. Saw one or more striking blue hummingbirds. They frequently land and while feeding and often flit from rock to rock to perch. The rocks maybe only a foot high, although larger boulders and bushes are available for perching. For a time he perched in front of a mine tunnel. Went back to the tunnel at 7:45 p.m. with carbide lamps just as entered a hummer took off and flew widely, hovering in front of me. It was trying to leave the tunnel and I was waving my arms trying to keep it in. In the dimness it flew into the carbide flame and extinguished it and thereby escaped. Another hummer took off when I had gone in another 6 feet. This one too flew into the carbide flame and extinguished it, but by using my emergency flashlight I captured it. Then I saw a nest attached to the ceiling with a bird in it. Grabbed it. It was warm to the touch. There were a large quantity of small bird droppings at the entrance. Dec 8 Found another blue-stone tunnel about 30 feet higher on the hill. This contained but droppings, an old hummingbird nest, and near the entrance bags of bird droppings remnant of a heap of candle droppings. Did not disturb anything in expectation of going back late tonight to collect more hummers and get temperatures Dec 9. Lower (nest tunnel) 5 x 5 1/2 x 75 ft. Temp. at 12:30 a.m. 15°; outside 5°. Nest 18 ft in and 5 1/2 ft above floor. Most of birds were in first 12 feet. Temps at 12:30 noon on sunny-
