Greater Shearwater to which I have previously
compared it. Some birds on attempting to rise
would strike the top of a wave and drop

perhaps panic-stricken or more probably
miscalculating the speed at which we were 
moving flew directly against the side of the 
ship in the vain effort to pass across her 
bows. Still others sitting with wings spread
and heads raise allowed us to pass within
a few rods or even yards without flying.
I had many birds within twenty-five or thirty
feet and noted their color and markings
accurately as follows:
Cap slaty; back and wings plain, faded brown
the primaries black or nearly so with much
white near their tips, the secondaries perhaps
narrowly tipped with also; upper and under
tail coverts brown; tail dark brown or blackish
with a broad sub-terminal band of white and
a terminal dark bar about an inch wide; a
conspicuous and broad collar of white extending
quite around to neck behind; under parts
pure white [?] on the under tail coverts and
the sides of the breast where the brown of the
back extending down below the bend of the folded
wing formed a narrow dark bar; slaty of cap
descending just below the eye but the sides of
the head and neck below this pure white
