_Specimens examined._--Total number, 31 (18 males, 13 females), as

follows: Caroline Islands, USNM--Ponapé, 2 (Feb. 12); AMNH--Ponapé,

29 (Nov.).

_Nesting._--According to Coultas (field notes) the nest is placed

in the top of a coconut tree or in a hollow of a large forest tree.

He says that one egg is laid, but does not record dates of nesting.

Four of the birds taken by Coultas at Ponapé in November had

swollen gonads.

_Molt._--Specimens taken in November by Coultas were either in

fresh plumage or were completing the molt when obtained.

_Parasites._--Uchida (1918:484, 493) found the bird lice

(Mallophaga), _Psittaconirmus harrisoni_ and _Eomenopon

denticulatus_, on the Ponapé Lory.

_Remarks._--There is little written information concerning the habits of

the Ponapé lory. Mayr (1945a:291) describes the bird as being "very

noisy" and with "habits apparently similar to _T. haematodus_." Coultas

made a number of observations on this species; some of these unpublished

notes are essentially as follows: _Trichoglossus_ is common on Ponapé.

It is found everywhere on the island, preferring the coconut palms; it

is noisy and quarrelsome. The parrot travels usually in small groups of

two to six or eight birds, keeping up a continuous chatter all of the

time. This chatter quiets down into a very pleasant-sounding

crooning-tone after sunset. _Trichoglossus_ is a continual nuisance to

the hunter, inquisitive and easily attracted by the slightest noise, to

which the bird responds with a frantic yapping that frightens everything

within a radius of a mile. One sometimes finds a bird alone working

quietly about among the low trees of the high mountain ridges. The

natives' name for the bird, "se ridt," means "always hide out in rain."

The bird stays under a big leaf and keeps dry during the rain. This lory

is intelligent, easily tamed, and sometimes learns to repeat a few

words.

_Evolutionary history of Trichoglossus rubiginosus._--The Ponapé Lory is

the only native parrot in Micronesia. It is an aberrant species and

seemingly is of long residence on the island, as indicated by its

differences from related forms to the southward and southwestward. The

bird shows some relationships to _T. ornatus_ (Linnaeus) of Celebes, but

the plumage of _T. rubiginosus_ lacks the brilliant red, green, and

yellow of this bird. The plumage of the Ponapé Lory is also softer in

texture; this is a character exhibited also by other Micronesian birds,

for example, _Cleptornus_ and _Colluricincla_. _T. rubiginosus_ and _T.

ornatus_ correspond, however, in having the feathers of the breast edged

with blackish. _T. rubiginosus_ resembles also _T. flavovirides_ of

Celebes and Sula in that the edges of the feathers of the breast are

dark, no markings are present on the inner web of the wing, and feathers

of the upper back are edged with dark coloring. _T. rubiginosus_ may

have been derived from either of these two species; however, it shows a

close relationship also to the _T. haematodus_ group from the Papuan

region. In any case, the Ponapé Lory, isolated in Micronesia, has not

the multicolored plumage of its relatives and has, instead, a rather

uniformly colored plumage. The presence of this parrot at only a single

island in Micronesia is difficult to explain; perhaps at one time the

bird was more widely distributed in Micronesia, or it may be that the

population represents a single successful invasion to Ponapé. Like

_Aplonis pelzelni_, another endemic species at Ponapé, this lory may

have reached the island as a straggler, perhaps being carried north by

the prevailing winds in the post-nesting season.
