Fleet, R. 1964--notes by species--Kure (Red-tailed Tropicbird) April 29--Observed this sp. bird on nest scratching head with right foot over wing. Rats killing all chicks. Skin them out and eat some (?) or all (?). Approximately 350-400 eggs on island. 3-23--Seems as though pair that don't as yet have egg tend to sit together near prospective nest site in morning. Later in day one? or both? display in air. 3-24--Pair seem to sit together just before egg is laid. This would indicate that d takes over almost imm. after egg is laid. Today 2 ?s gave repeated chirping call. 3-27--Changeover bird returns, sits facing bird on egg. Repeated Al-Al calls exchanged (see #103) 5-27--Bird near N tower constructing nest. Bird sporadically pushed sand from nest area with feet. One foot at a time and frequent pauses. Definite bowl about 4 inches in depth.
