Observer very much doubts the validity of Sarasin's
sub-species and in spite of failing to collect a series be-
cause of leaving it too late the few facts collected seem
definitely to point to the invalidating of the species un-
less Lifu also is included. A tendency to smaller sizes on
Uvea might be acknowledgable because of poor food conditions,
but observer doubts a full subspecific difference is warranted.
The date of collecting of Sarasin's type specimen if occurring
between May and August would seem definitely to point to its
being an immature and outside those dates could just as likely
as not be one also. Though I do not believe Sarasin did so,
I believe a collector could if he wished in the seasons when
birds are more numerous by selecting only the smaller adults
shot (and especially in females which even elsewhere show a
range towards smallness) create a series showing a very much
smaller race of birds. Even if all specimens shot were
taken, observer believes, and it seems more than likely
taking food into consideration, an impression of a smaller
race might be created quite accidentally and this is probably
what occurred in Sarasin's case. One would expect strong
large birds to leave the island first (and I believe they do
leave definitely) and this would increase the percentage of
smaller birds which is probably why such an impression was
made on myself subsequent to February observations.
Habit observations were necessarily few and the
following are compiled most from reliable natives. Nesting
of the species on the island is little known to natives,
probably not because of the rareness of the actual happening
but because of the natives seldom visiting the tall forest
