27 Dec. (cont.) 1 of the Kittiwakes (imm. ) remains, 
moving over the island freely. The Glaucus-winged 
Gulls stay either at S. or N. pt. Booby behavior 
at night. 
B 
gone. 
28 Dec. Banded the gull and released him at the beach. 
Be is so weak that he aan barely stand, even though I 
forced a rat down himT Dennis and I get some pictures 
cefore he flies off ^nd drinks from the lagoon. We 
put a 737 band on him, but this seems much to large, 
even though this is what Dept, of Fish and Game recommends 
Perhaps his legs are small due to his weakened and 
thinndd condition. Spun down blood, cleaned up lab, 
worked on Lays&ns, painting some not marked. Two 
:iests have been destroyed, the eggs broken and contents 
probably eaten by rats. 
We staked out the Booby colony, putting stakes in at 
33 foot intervals. Next the coliny will be mapped 
out and platforms designated. The birds have cleared 
platforms to dance in, and one pair (R13-14) have two 
platforms, dancing alternately in them. There is much 
toanipulating of nesting material at the present. 
Chught a Bristle-thighed Curlew, but he escaped from 
.he lab before I could band him. 
29 December - Dennis and I bled and took measurements and 
ectoparasites from 8 Laysans - one bird had an extremely 
worn band which was replaced - the band read 72 - - - 
. H'i cj uw'f ^-This laysan, if the 40 means year banded, was banded 24 
years ago. At any rate, it is an old bird, and was not 
tjled. There were 4 Glaucusgwij^ged Gulls at south point, 
including the one unable to^iiy. One bird regurgitated 
as I approached - much rat fur and many chelipeds from 
cirabs. The birds can now be approached to within 150' 
before they fly off. Checked Laysan nests, observed and 
photographed various displays of the Boobies - in particula 
s|ky-calling and agonistic encounters between R13-14 and 
R15-16. After dark Dennis and I painted 5 Blue-faced 
Boobies in the colony as follows:
