Hummingbird 3 Jan. 1 4 km. E. Juli, 12,500 ft. While setting traps along the "seaward" end of the peninsula along the rocky shore, found 4 shallow caves, 3 of them with hummingbird nests hanging from its ceiling. The caves were "imitative" sea caves, but heard one other active sea cave. One cave about 5 feet high, 5 wide and 7 deep had a nest with 2 eggs. The nest was more like a crevice 4 feet wide, 15 feet high, and 20 feet deep. This had a nest about 12 feet up containing young. This and one other cave had small bat-like droppings, maybe swallows // Went back to 2 of these caves at 10 p.m. In the big crevice were 3 sparrow hawks, 2 of which I caught in butterfly net, 1 before crowed flycatcher, and 1 hummingbird. The female sat on the nest while I caught the other birds. Her rectal temp. was 39° F and 1 of this 2 young 38°. Both young were almost fledged and had mid-central streaks of brown feather which I think in character of adult S. One hummingbird escaped from the crevice. On the cliff about 50 feet from the crevices and 25 feet up two corpses sat in contact but did not fly. The nests were well cemented to the ceiling and were made of wood, feathers (many of them not in another cave [hummingbird]), grass, leaves, moss, etc. 100 yds away caught the female on the nest (warm to touch), the eggs in first few days incubation. Also several males locked in a crevice was an immature streaked sparrows? (see tarsian specimen; tail pulled out trying to drag it out of rocks) Jan. 3 See journal for Jan. 3 Feb. 6 Found 2 nests in gorge of Rio Huerque. One a shallow cave, the nest containing a single young ready to fly. Green gorget and
