MYIAGRA CALEDONICA VIRIDINITENS (GRAY:-
UVEAENSIS (SARASIN):- Observer
did not have the opportunity of actually comparing specimens
from Uvea and Lifu side by side, but judging from memory of
the amount of variation in the white on the tail tip, doubts
whether Uvaeensis would stand, and it would be hard to know
just where any line of demarcation could be drawn as regards
white on the tail. As far as I can remember specimens from
both Lifu and Uvea show a wide range of variation in the white
on the tail. There may be other differences present though
observer doubts they are regular. Observer believes Myiagra
is one of the later arrivals on Uvea, probably from Lifu,
and is not yet fully established or rather has not yet
reached its full numbers on the island. Considering the
suitability of the area and the great amount of food supplies
of this species which are available, its present numbers do
not represent more than 10 to 15 per cent of a normal popula-
tion for this species. Naturally in such a position of evo-
lution, a new subspecies is possible or may be even only just
evolving and the latter may actually be the case at this date
and account for the variations, though in the face of varia-
tions on Lifu it seems doubtful.
Though a fair series were collected, these took a
considerable time to complete, and the species was sufficiently
rare to warrant every sight record if it being recorded from
day to day. Sometimes several days passing without it being
seen.
It seems to be very evenly distributed over tall
forest, short forest gardens, and coconut area margins and
mangroves and coastal scrubs where such exist, with a slightly
