SKETCH MAP OF UVEA IS. SHOWING HABITAT AND DENSITY
OF POPULATION OF NYMPHICUS CORNUTUS UVEAENSIS
From notes made between Feb. 8th and June 24th, 1938 status
and distribution of Nymphicus on Uvea Is., Loyalty Is., W.
Pacific (sub-species confined to the area shown)
Approx. Estimate: Reasonably accurate but subject to some
+ or - of 10-15% error
Natural habitat entirely suitable for the species and
inhabited at present date by the species. (Numbers given
are approx. and include the birds of surrounding areas of
shorter forest.) These areas may be considered as areas
of dense population for the species and are areas not
likely to be great encroached on or diminished to any
great extent for many years to come under present condi-
tions on the island. Only exceptional unforeseen or un-
usual happenings are likely to alienate any extent of the
area to the birds or decrease their numbers providing
adequate protection from live bird fancier and native
catcher persecution is granted to the species.
Areas of shorter forest at present inhabited by small
numbers of the species (sparse bird population) but
capable of carrying a very much larger population as
numbers increase. This area is at present much visi-
ted by birds from more densely populated tall forest
areas and carry a fair number of permanent birds which
nest in the area. This area is subject to gradual
diminition by increase of cultivation but only to a
small extent unless the native population makes a very
large and sudden increase; a more or less static
position or saturation point having already been
reached as regards cultivation and native ratio with
the present population.
Areas which are at present under cultivation but are
still being visited by the species (heavy shading much,
light shading, occasionally) but which will in time
become entirely alienated to the species probably,
unless it can adapt itself to the altered habitat.
These areas may in course of time disappear and be
quite unsuited to the species.
