DeBenedicti's 1964 72 2 Feb. Punta Espinoza, Fernandina I.s., Galapagos. became aware of Yellow Warbler song about 5:27. Frigate birds coming out of the mangroves in 2s, 3s & 4s, flying directly without circling. One large departure of c. 15 birds. Most birds out by 5:45 and most yellow Warblers quit singing & began chirping by this time. Got up early and didn't do much. A Geospiza singing in camp. Dr. Miller shot an ad. and fr bird molting from (1st to 2nd year plumage - head and neck dark with no clear hood) Larus fuliginosus. Poked along the shore for white then took Dr. Miller's pistol and hiked around the large lagoon Kister and I visited yesterday. Went there directly, shooting a Mocker at the start. It was foraging on the ground at the base of mangrove roots. The mangroves along the N side of the lagoon are 25 ft high & c. 15 ft. thick goin to a secondary channel. Yellow Warblers were very common in this and mockers spaced along the trees. The Warblers frequently fly out 50' to perch on the lava, then fly in. Can't see if they are feeding. Many 5" inch Tropic- birds along here. Saw 3 G. fuliginosa along here, + 1 Semipal. Plover + 6 Ruddy Turnstones. Along the W side the mangrove run 5-10' higher, and are 35 to 75 feet thick, very dense. Some dry, soft [illegible] bottomed pools here; saw a mocker industriously picking up mangrove leaves and flipping them back & side (one motion) or thrasher- like flipping leaves side to side. It was picking up food from the ground and swallowing it. Shot at it but missed. Saw a nice black G. fuliginosa here, and flushed 2
