We heard them singing on Hood and Gardner-near-Hood 
in early February. Birds taken about that time had large 
reproductive organs. 
On January 31, in bushes close to the beach at Gardner 
Bay, Hood, I found two or three nests, shaped like Geospiza 
nests, but much smaller. They were built of roots, and I 
suspect belonged to the Gray Certhidea.

Although widely distributed, this species is by no means 
abundant. At no time did we find it in flocks, although in 
some localities quite a few were seen. It seemed to inhabit 
the arid region chiefly, although on Abingdon and James 
it was found in the humid belt. We first met with it on 
South Seymour on November 21, when two were noted. ° 
Two were seen on north Indefatigable, November 25. On 
the south side of that island in January, two or three were 
taken at the water hole near the beach at Academy Bay. 
Mr. Beck saw several inland in the dry region. In the 
middle of July in the same locality, I shot two very large- 
billed ones and a third one was seen. On northwest Inde- 
fatigable, south of Conway Bay, on July 21 and 23 two 
were taken. 
On Jervis quite a few were seen during our visit in the 
latter half of December. They were noted from the beach 
to the summit of the island. One or two specimens had 
white feathers in the abdominal region. 
James was also a stronghold of this species. They were 
observed mostly in the moist region, although on Decem- 
ber 26, at Adams Cove, on the arid northwestern corner of 
the island, two or three were taken, one being a male with 
large testes. A black male taken December 28, had a white 
feather on its neck. In the humid region on the west side
