M. Redon, 1942 6 Calliope Hummingbird E. Fork Sheep Creek, Kings Canyon, 5,500 ft., Fresno Co., Calif. Ladera Above, A. Fork Kings R., 4,600 ft., Fresno Co., Calif. May 23, 1942 This time she faced J. Russick who had moved on up the trail. A second or so later she left the nest, flew under the branch & entered the nest, always from the same side. After about 2 min. J. Russick stood up; the hummingbird left and about a minute later was again in the nest. J. Russick moved closer to me; hummer sat with head turned & beak pointing sort of between us, apparently watching us both. Sun now striking nest & hitting bird's breast; neck & head in shade. Hummer sits 8 min. moves, probably because I or too resty gesture on my part toward my field glasses. Returned after about 1 ½ min., this time without zigzagging & not stepping directly into nest from the same side as usual. Sits fairly erect in nest coil entire head visible. Beak held often at slight angle downward from horizontal Sun now no longer hitting nest. Can be seen to jerk head very slightly with a sudden movement, & quite noticeably after a sudden move apparently from the one of two persons on whom her attention had not been focused. Diagram indicating nest location - a) Main branch about 15 feet from ground Tree = on slope + nest = exactly above 1 ft. from path edge. b) Secondary branch: three glasses one can see that nest is set out, with some fibers holding it down. Nest = 3 feet from trunk = 2 ½ ft. from end
