M. Cedar, 1942 5 Colliope Hummingbird Cedar Grove, A. Fink King R., Fresno Co., Calif., 4600 ft. May 23, 1942 Arrived at 10:10 to the site of the hummingbird's nest, it was impossible to approach without disturbing her. She returned to the near cottonwood in about 5 min., after first flying in a swift circle around the nest tree and flew going to the oak larger alder in back of the nest. There she perched on a branch about 25 ft from the water, sitting about four feet from trunk of tree ruffled her bell by drawing it along the branch and fluttered her wings a few times. Then, she flew to the tree (another oak) this one with leaves just coming out and sat on a branch about 4 ft from the ground for a second. She flew to the nest tree finally, just zigzagging under the branch which holds the nest several times & then flying around the tree, over and then back to the vicinity of the nest, a few more zigs & finally into the nest. This time she appeared to fly in, fluttering her wings as she settled here. She sat facing me, i.e. East. I timed her stay to eight min. J. Ross came up then, and the hummingbird flew away. Stayed for a few seconds, circling the tree, then settled on a branch in the alder behind her, this time at about the level of the nest, about 35 or 40 ft. above the water & again fluttered her wings spread, scrunched with one foot, zigzagged under the limb & entered (stepped) into the nest. A second or so later she flew off & returned immediately.
