when we were out of the range of the species, and on all of 
the islands of its range, except Jervis, Narborough, Abing- 
don, and Wenman. It was in song the least during the nest- 
ing time, when it was rather inconspicuous. Besides the song, 
this species also has a sort of chirp of several notes used as a 
signal of alarm and as a call note. Birds were heard in song 
on Barrington in July, while they were not heard on Indefat- 
igable. I one day heard one singing while it was sitting on 
a dead tree in the middle of a large salt lagoon on southeast 
Albemarle. 
The following notes were made on the condition of the 
reproductive organs: 
October 21; Barrington; somewhat enlarged. 
October 31; Villamil, Albemarle; testes enlarged. 
November 6; south Indefatigable; considerable sexual enlargement. 
March 13; ten miles west of Villamil, Albemarle; large. 
March 26, 27; Tagus Cove, Albemarle; large. 
April 17-19; north Narborough; large. 
September 22; south Abingdon; small. 
September 24; Wenman; medium-sized. 
On Bindloe, on September 17, I saw a pair in the act of 
coition in a tree. 
Owing to our absence from the greater part of the range 
of this species during the breeding season, we found it nest- 
ing only on Albemarle. Two occupied nests were found in 
bushes of Zanthoxylum pterota beside the wagon road in the 
humid forested zone on the mountain of southeast Albemarle 
on March 8. Both were about 12 feet from the ground. One 
contained three eggs with incubation begun; the nest in this 
case was of twigs, lined with grass, hair, etc. The second 
nest contained three newly-hatched young and two eggs ready 
to hatch. The parent of these was on the nest when it was 
pulled down; she uttered a cry and flew off a few feet, but 
made no other disturbance. 
On March 12 a nest with a bird sitting on four fresh eggs 
was found near the coast about 10 miles west of Villamil. 
The nest was in a bush some nine feet above the ground, and 
was made of twigs and lichens lined with roots, grass, and 
hair. The bird made two or three outcries when I reached 
for the eggs.
