The soil. The bob pattern is very simple and much more like the Ferrandina form than the Santa Cruz one. They are not as common at first appearance as the latter two forms, however. Many young (3'-5') animals about. When we landed there were several frigate birds circling about, out of which appeared to be magnificent. Later when Bob Pyle and I walked about the Pt. We saw at least 1 juv and 1+ senior, the juveniles clearly showing rust color. We walked around the Pt., then cut back to the camp. The N side of the Pt is low, mostly cobble stone beach with a few stretches of sand. No nesting seabirds here (except a very tame pair of Oystercatchers) but fair #s of sea lions. The S side of the pt. gradually rises to a 3-400 ft high cliff; A strip of bare ground, widest about due south of the camp, surrounds the coast, and the scrubby vegetation described above lie between the two coastal strips. Beginning almost at the Pt. Masked Boobies are nesting in a strip 1/6 1/10 nest wide on this flat along the shore, extending about a 1/2 mile E from the Pt. Inner side of this strip, entry from the open area, into the well vegetated area is a dense colony of Blue-footed Boobies, which E of the Masked Boobies spills down to the cliff.
The Masked Boobies show a considerable variation in the reproductive cycle, although most have eggs and newly hatched young. Saw a few young
