P. DeBenedicts 1964 23 Jan. Academy Bay. Santa Cruz Is., Galapagos. 2-3 inder from the ground. Here a call, repeated, with a Vireo like structure and chased a Cactospiza from the vicinity. Found 1♂ Platyspiza singing in an crecta. Song a cwee cwreeee cha, low pitched, rough. Bird climbing but not feeding. At the branchia found a Vermilion Flycatcher, about 300 yds further along the path saw another deek male (orange belly) give flight display, very simple compared to cliff brices. He tried clip up and down, slow wing beats, 1 dip / 3/4 sec., making a snap noise at the top of each arc and sallting cha wi during the arc as such: cha wi (snap) cha wi (snap) cha wi (snar) path roughly circular, didn't land but starting position. Saw one nice ♀ G. megistis, all black, live. Song very deep and "nasal", rough. near the top of the dry area, a flock of Geospiza flustered leaving a baby cuckoo, which I captured. Found another in a tree c. 25' away. This bird couldn't fly, gave a rough call when handled. Bird in the tree gave a double, hollow "coo coote" very deep, at intervals and was able to scramble through the bush, fly 2-3 feet. Saw Camarhychus parvulus gardening nest material, a hanging lichen, for nests which were way up in trees and made of the lichen. Very little display when gathering. Geothiclea has
