This is the story as I understand it.
One night in January, a seabird flew through an open door into the home of Lloyd who lives in the old Clunies-Ross mansion on Home Island in Australia's Indian Ocean Cocos (Keeling) Islands. Thinking the bird must be sick he put it in a box and next day passed it into the care of the National Park Ranger, Ismail MacRae. Ismail took it back to his office 18 km across the lagoon on West Island and force fed the bird on fish for a couple of days. Somehow, the bird escaped, returned to Home Island and again flew into Lloyds home. Lloyd tried to toss the bird out but I think it returned again. Following a day of gale force winds the bird did not return!
From photos taken (three are to put on ABID), I identify the bird as a
Bulwer's Petrel Bulweria bulwerii, a species not previously recorded from the atoll or surrounding waters but known to occur at least in the northern Indian Ocean. But the foot colour is not as described in the literature. Onley & Scofield say 'Legs pale'. HANZAB says 'tarsi pink with outer side sometimes darker'. That's OK but goes on to say 'feet usually greyish flesh with some pink on webs'. On this bird they are virtually black. Can anyone explain? At least in spring, this species is common off northern WA and in the Capricornia Channel off Queensland with vagrants to Victoria. Beach-washed corpses are rare anywhere in Australia and I know of only one previous record of a live bird ashore on any coast in Australia. That was a bird at Broome which later died in care.
