P. DeBenedictis 1964 Feb 12. Punta Suarez, Espanola ( Hood) Island, Galapagos. Out in the brush saw on thursday vigorously and as powerfully and efficiently as a Coif. Thresher Didn't see much other foraging, but lots of forali- zation, much like the Santa Cruz birds but possibly a little throatic. One bird in camp has no tail. Two species of Geospiza around the camp area, ? fuliginosa and conirostris in about a 2:1 ratio in favor of conirostris. The latter is a large, laterally compressed-billed bird, which feeds very close to the ground (there is little alternation) for the most part. Bills dark but almost no singing. The other pinch is long, sharp beaked > like the Franceling Is. fuliginosa. The latter is not too small, about the size of Academy Bay birds, while the former is about the size, bill and body, of a large forlis. Probably correlating with the lack of ? maguanae, Yellow Warblers are not to be found here and Certhidea is common everywhere. It's pale, grayer on the back with almost no buff on the breast; songs very like Santa Cruz birds. Fly Forage close to the shore in quite low (2 ft high) very close to the shore. I wonder how much the scarcity of Certhidea in the lowlands of Santa Cruz is due to ? failure to compete with Peudeica, which is most successful where it takes hold. The Tropicbirds here is very strikingly unlike any I have ever seen before. It is a drench animal, quite reddish (about the back); very much the same reddish color as
