McKean Island (cont'd) Species No. Banded No. Returns Brown Booby 11 -- Red-footed Booby 81 44 Gray-backed Tern 100 -- Sooty Tern 7604 45 Fairy Tern 127 17 Blue-gray Noddy 200 7 Hawaiian Noddy 15 -- One of the most interesting finds was an all black storm petrel, possibly a dark phase of the White-throated Storm Petrel. If so, this would be the second species for which a dark phase has been found on this island and which has not been previously reported in the literature. Baker Island 23 hours were spent ashore here carrying out the survey work. 12 species of birds were observed of which four were breeding (an increase of 3 in the number of breeding species over previous trips). 214 birds of three species were banded with 15 returns recorded. The absence of cats seems to be the factor responsible for the increase in bird numbers and also for the increase in the mouse population. The presence of mice had been previously known only from the remains found in a cat stomach. On this trip almost every board had a mouse hiding under it.
