Feb 15 Punta Cevallos, Espanola (Hood) Island, Galapagos.
stage in the cycle as the Pta Suarez birds (eggs to 1/4 grown young, mostly near hutting [either side?])
In #s it was searched only by Creagurs which was even commoner than at Pt. Suarez. Nests with eggs were every where; I walked up to one bird in a brooding position (belly on ground, carpal out, breast feathers erected) which did not move until I touched it with my foot; its nest was empty. We saw 3 Peregrines eat the egg contents of a Creagur nest (1 egg), this obtained by poking a hole in the end of the egg & (drinking) the contents. Missed a picture of this. (dam!). The workers twice followed me into the colony, hoping for eggs, but didn't have any luck; Boobies eyed them carefully and won't get off the nest for anything. Some of these nests contain very small eggs. The brush comes close to the cliff at one spot, then opens to a wide area with a twist (where the cliff becomes much higher).
From this brush area to the DW there were many signs of abortions (feathers, bones), and Willy said he had found c. 300 here (vs. 1800 at Pt. Suarez). There were almost no Blue-footed Boobies here at all, thus only scattered pairs on the high south cliff.
Red-billed Tropicbirds were the 3rd commonest seabird here, buzzing along the cliff but didn't see any lands. The next commonest species seemed to be Greater Frigate bird. We found 4 of them on the cliff in clumps
