P. DeBenedictis 1964 Feb 1 Punta Espinosa, Fernandina Island, Galapagos. Got up at one and circled to the N. Yellow Warble song consistent now. All the Frigate I have seen were going W. 5:52 a swarm of 16+ 2 separate Frigates formed by aggregation of groups of from 2-4 birds and gradually circled W. 5:56 broke up 10, circled N, breaking into 2 groups of 5. A few single birds in between. Heard 1 1/2 tatters at 5:58 Y.Warble. drop now, almost no song. 6:02 heard Semipal. Plover "chee-ee," and c? Turnstone or Morice. Can see the pale color on Frigate birds now and c. 5 came back S. 6:07. Heard Oyster catchers. 6:17. Few of a zimple Yellow Warble song than I heard earlier. 3 sw~ to do sw~ to do; 1 1/2 finches leaving the mangroves now. 6:23. Saw c 5" (total length) Tropiculus actius. Stopped at this Pt. A couple of Ad. haeus fuliginos showed up during breakfast and Brown Pelicans and Blue- fotted Boobies conspicuous today. Picked the baby Oizonyps. The nest site is kind dense, but is accessible by a lava fissure from the beach side. The fissure was in exposed lava 8 yards from the mangrove t about a few from the sandy beach. The crevice formed a sheltered runway to the mangroves. Little droppings near the nest but several scattered lower. The nest and crevice bottom is floored by fine sand, and littered by small bits of bone, possibly atoms from mangrove berries and leaves. A few mouse droppings while [illegible] in open places on the lava. 2-3 yds from the nest. The nest material earlier described as straw is strips of mangrove bark 1/8-1/4 in wide and 1-4 (mall 1 4 1/2") long largest piece of bark 2 1/2" long x 1/2" wide. from a fairly large branch, little indication of reuse of nest site, beyond mangroves beneath.
