Marshall, 1945
Palau
Rukia palanensis
Constant loud grating notes. A very active, noisy, bustling bird.
Favors shot-up woods where vines drape the dead trees to a great height.
Song: Very high-pitched canary-like whistles & trills. The trills continue as a background all during the whistled notes so that a single bird sounds like several singing at once. The open whistles of descending inflection "teen teen, teen" have a strained quality as if they are being squeezed out & the bird is in agony. After a series of these (without trill) he goes into a long trill that surges somehow, then the upward inflected whistles with trill undercurrent. This song is like no other bird I've heard. It has this remarkable orgasmic, hectic quality.
