Lehner P. 1965 1965 Jan. 1 we ushered in the first day of the year with the gypwire census; Doc ran the first couple of hours and checked half the mouse traps before I had a chance to get out of bed; saw Red-footed Boobies in mating behavior today: One bird (apparently female) sat on ground at probable nest site while two others (apparently males) flew back and forth swooping close over her - every time they would approach, the sitting bird would squawk at them in what appeared to be a threatening gesture. Observed a male adult Great Frigatebird take a Tribulus runner out to the rocks north of the Signal bldg. Two Common Noddies were observed in close flight, side by side - apparently mating flight After supper we once again sat grid traps.
