January 1965 - BCF cruise
White-necked Petrel
Eight birds were observed in January, of which 5 were almost
certainly this type, while the other 3 may have been this type or the
very similar Juan Fernandez Petrel. Distinction between the two birds
is not always possible.
Juan Fernandez Petrel
Forty-three individuals were recorded in January, a continuing
decline from the 156 seen in December. No marked distribution pattern
was noted. Considering that the breeding season for this bird began two
months ago it is surprising to find such a sizeable population still in
the area. Evidently it is never wholly absent from the area. As the
plumage of this bird wears, it more closely resembles the White-necked
Petrel in that the dark edges of the white nape feathers wear off.
Bulwer's Petrel ?
One bird, thought to be this species, was seen imperfectly on
21 January. This species is not expected to appear in numbers in the
area until March.
Leach's Petrel
Eighty-one birds of this species and an additional 7 presumed to
be this species, although imperfectly observed, were recorded in
January, a substantial increase over the 53 seen in December. Numbers
were distributed fairly uniformly over the whole area except for one
concentration around 18°N - 157°W where 37 birds were seen on 6 January,
including a flock of 14. One bird flew aboard on the night of 6 January.
It was collected.
