ZONES OF BIRDLIFE
SPECIAL INDIV. BIRD SPECIES
Lichmera: Notes made on this exceedling common species.
This species is very common and plentiful anywhere on
the island where coconuts are and except in mangrove swamps is
never found far from coconuts. I found nowhere in forest lands
did the bird penetrate more than 150 yds. and generally it was a
rare visitor as much as 50 yds. in, only a very few getting much
beyond that distance. Up to 50 yds in is fairly plentiful,
especially ♀ and imm. which greatly outnumber ♂ in this areas.
♂ outnumber ♀ in coconut areas by about 20 to 1 but in forest
and scrub margins ♀ outnumber ♂ considerably. The exact ratio
is rather hard to judge because of immatures but I believe is
about 4 to 1 approximately. ♀ are definitely very much more
plentiful than on Mare Is. and the over all ratio of ♂ to ♀ would
probably be about 10 or a little more to one ♀. The greatest
numbers of ♀ are found in the first few coconuts or lines of
coconuts near scrub and for 10 or 15 and decreasing up to 25
yds. into forest or low scrubs. Almost invariably if a female
is found well out amongst coconuts, low brush or shrubs or a
single large dark foliaged tree will be found within 25 or 50
yards at the most. At times when in forest I thought I had found
Lichmera well in and far from coconuts but invariably found a
small isolated patch of coconuts on going a little further, some-
times no more than half a dozen palms with perhaps only 2 or 3
Lichmera inhabitants or larger numbers of palms and Licherias.
In such small patches ♀ almost invariably outnumber ♂.
An interesting fact is that though Lichmera is almost
a purely coconut living and feeding bird, probably 90 per cent
