Fleet, R. 1964--notes by species - Kure 5 Frigates January 30--Frigates observed from tower to be displaying (gular inflation) on central roost. Also (d's) observed to be collecting nest material in form of sticks. Heard to give peculiar whinny call, periodically flip wings. February 6--Observed ? nests in various stages of completion in central roost. In- fiation of gular pouches of males becoming more frequent (also more inflated). February 12--Frigates d's with inflated gular pouches stretch wings out and shake them (quiver) and give whinny cry. February 21--Frigates egg seen by G. Kridles in central roost. Nest building still going on. February 27--Collected 2 adult d's with broken wings. C. R. count up drastically to 260 plus. March 19--Observed these birds robbing RFB nests of material while RFB were away from nest. Frigates will follow above and behind me on beach--seem very curious. Had one bird catch a stick which I had thrown in air. March 30--Marked one nest with egg. ? on nest left. Today there was no sign of nest remaining. Obviously robbed of material by other birds. April 11--Marked about 25 nests but have already lost 1/2 or so. Birds now roosting on guy wires as they were last November. Just started again this week. April 14--lost almost all study nests. Other birds steal nest material, destroy eggs, etc. when marked bird is frightened away. April 15--This species especially susceptible to loss from antenna. April 17--Observed bird in AF pick up fish thrown up by RFB off ground and eat it in the air. April 29--One nest constructed with red flag and wire from our study area.

Fleet, E. 1964--notes by species--Kure 7 Red--tailed Tropicbird January 29--Have seen eight flying over island, in groups of two or more, calling Periodically fly out to sea (over lagoon). Apparently roosting in scaevola (all adults). Feb. 7--Saw 16 of these birds flying about island today. Two distinct groups, one over N part of island, one over S. Feb. 12--Increased to at least 30 individuals by Feb. 10. Usually fly about island in groups of pairs. Squack andfly backwards (flapping wings heavily and assuming a head-up verical position. Periodically swoop low and hover over clumps of Scaevola. Have been observed diving into scaevola. (Hover about 3 feet above sc-evo1s, fold wings and dive in.) Two birds have been captured on ground. Plumage has pink cast, bill cherry-red. Feb.--Increased to 60 individuals in air. No nesting. Feb. 28--Saw bird at SP with blue X on breast. March 2--Counted 150 birds in air over island today. Banded two (2), both had pink wash to feathers. No nesting observed ss yet. (One bird with chick on Midway and several on eggs?) March 5--Banded two birds with eggs on NEpoint, in scaevola. Eggs are speckled reddish in color and between.Bonin and B.F. Booby eggs in size. Very little mest preparation: circular area, slight depression, some few sticks and leaves. March 6--Banded two birds with eggs near B. F. nest #6. Band No. 12661 and 12662. Counted 500 in air over island Daily cycles should be extracted from activity study data. No. 12654 on egg at Biltmore Rd. March 7--Rained all day. No PTTB in air. Believe birds leave for sea about 1600 (1500) every day. March 8--Banded 14 (and 2 by Wirtz) birds today. Saw one individual knocked into

Fleet, R. 8 1964--notes by species--Kure (Red-tailed Tropicbird) water by Frigate; another pursued by 6 Frigates. Alarm posture: head depressed on neck; wings back along body, shoulders flared forward and out. Black scapular feathers showing. March 9--Most of island has been searched for nesting birds. Total of 6 nests found; seem to indicate early breeders; no birds with eggs found. Flight patterns over island seem to indicate location of roosting birds (beneath them). In display tail is switched from one side to other every few seconds: direction not correlated with flight direction. Two of birds banded have thrown up--one squid and one flying fish. March 10--Very windy today and saw only 2-4 birds in the air. High winds definitely affect this species, but not others. Saw one individual (#5): black on nares ran to tip of beak and black extended behind eye about 1 inch. March 11--Found four more eggs today. Cone of birds in air mark best location. March 14--Palped two eggs in ? birds today. it is possible that ?s have a lighter colored beak--at least during breeding March 19-- Display call is a short, repeated croak--ach-ach. Alarm is same sound but longer drawn out scream and somewhat higher pitched. These birds occasionally vomit fish when handled--primarily flying fish and squid. March 21--Nesting birds sit in rain with head held more or less vertical allowing rain to run off. April 11--Cloaca of ? after dropping egg is enlarged, swollen and of a purple color. Fecal material runs free due to strained sphincter. April 14--now have 2 chicks. Nest #3 and 103. Approx. 2 days old. Incubation estimated to be around 30 days.

Fleet, R. 1964--notes by species--Kure Laysan Albatross Dance: Bobbing head and bouncing on toes birds face each other. Chew at one another's beak or clack beaks rapidly side by side. May at this time also rapidly shake head from side to side and emit a shriek: AEEEEE... One or both birds then stand on toes with head thrown back and emit a low moan. If only one bird does this other bird may just stand still at this point and watch. At this point birds tuck head beneath wing (eitherone) and preen feathers--time of this operation becomesshorter as dance increases in tempo. Removin[illegible] head from this position bird again goes into tiptoes head back position emitting a single hollow sounding CLACK from bill. Dance usually repeats from here. May or may not be followed by copulation. Aggressive: After fighting the dominant individual tiptoes with head back and moans only slightly differently from dance call. Notes are slightly higher. Egg-chick: Birds will defend nest by snapping beak and a sort of growling note. When egg and chick is removed and then returned or prior to sitting down the parent bird may emit a series of short bark-like cries. AE-AE-AE, etc., usually with beak partially open. This call is the same call used by chick to call parents. Feeding: Chick stimulates adult to disgorge by nibbling on side of adult's beak. Chick places its beak at right angles inside adult's beak and catches disgorged Food. Main staple food of these birds is squid and squid eggs. Eggs are pink in color and look like caviar. Sometimes adults have trouble in disgorging food for their chicks and may approach a nearby chick, peck and harass
