Quast 1948 Journal 127 June 19 San Jorge, 5 f ft, 25o 44' N, 112o o7' W, Baja California northernmost of a series running down the coast from here southward. Birds seen to date: Caspian (?) Tern, White Ibis, California Jay, Brown Towhee, Plumbeous Snatche, Semi-palmated Plover, Osprey, Raven, Vultur, Caracara, Purple Martin, and Reddish Egret. California Jays are common here in the Mangroves and "Mangle Dulce." They are most frequently seen in the vicinity of these plants which border the estero. Tevis said this after - noon that he had seen them eating the small red berries of the "Mangle Dulce" and I witnessed them eating some small crabs of about 1 in in length on the mud beach. The mud areas around the Mangroves abound in crabs and I have seen at least four types all of which live in burrows in the mud. The Mangroves vary in thickness from five feet in the thinner portions of the border to fifty or seventy five yards. Heard a clattering sound from the Mangrove across the estero this evening which Dr. Boren said was a Rail. Have seen no grass or salt-grass so far in the region of the estero. Small patches of salicornia occur in the flat places just
