find their food almost entirely. They were quite lively birds, 
jumping from limb to limb, and often hanging head down- 
wards while searching for food. 
In the humid region on south Indefatigable they were found 
to feed as a rule high up in the branches of the large Scalesia 
trees, which there grew to a height of 30 to 40 feet. One 
was seen in the humid region examining thoroughly a rotten 
tree trunk lying on the ground. On Chatham and southeast 
Albemarle they were also seen feeding head downwards in 
the trees in the moist zone. On southeast Albemarle they 
were frequently seen feeding in the mangroves, and chiefly 
in the “poison-fruit trees’, in the coastal region. At 1900 feet 
altitude on Banks Bay Mountain, Albemarle, I saw an adult 
feeding in a tree of the family Composite. On Cowley 
Mountain, Albemarle, Scalesia trees appeared to be their 
favorite feeding places. 
In the arid region 10 miles west of Villamil, Albemarle, I 
one day watched a bird feeding in a leafless, dead tree. It was 
apparently searching for insects, for it inspected every hole 
carefully. Finally it found one too deep for its bill. It then 
flew to a neighboring tree and broke off a small twig, about 
half an inch in length. Returning to the hole, the bird in- 
serted the little stick as a probe, holding it lengthwise in its 
bill. It proceeded to examine other holes by the same method. 
Mr. Beck and Mr. King said they had noted similar instances 
elsewhere. 
At Academy Bay, Indefatigable, one was taken while it was 
working over a rotten cactus limb. About Iguana Cove, 
Albemarle, they were feeding in the trees and bushes. On 
July 26, on South Seymour, one was noted picking the bark 
off a small tree, which grew near the beach, and eating small 
red eggs, probably spiders’, which abounded beneath it. 
They were heard singing in the “poison-fruit trees” near 
Villamil, Albemarle, on November 1. On March 12, in the 
mangroves about 10 miles to the westward of Villamil, several 
birds which had nests were singing. On March 19 and 20 
some of the birds above Iguana Cove, Albemarle, were singing. 
The condition of the reproductive organs was noted as
