with three newly-hatched young. While I was in the tree 
examining the nest the parents kept very close to me. ‘They 
made very little noise, but one picked my hand when I placed 
it near the nest. On February 23, in the same region, two or 
three young just from nests were seen. The species seemed 
commoner than it had been in the previous month. 
On the whole this species was fairly tame, but not nearly 
so tame as the Hood Island species. The Chatham birds were 
particularly tame and inquisitive in September ; probably many 
of them were immature and inexperienced birds at that time 
of the year. 
Birds with diseased feet were not uncommon and were 
observed at Basso Point as well as at Wreck Bay. Many 
species of land birds were noted in this condition at every 
visit we made to Chatham. Mockers were noted in October, 
January, and February. This disease appears to begin very 
early in life, as a young one with diseased wings, bill, feet, 
and neck, and but a short time from the nest, was taken on 
February 23. 
Cats, which are quite common, must decimate the numbers 
of this species to a considerable extent. During our stop at 
Wreck Bay in latter January, Mr. King heard two or three 
mockingbirds making considerable noise. and upon creeping 
toward them, saw a large black cat on the ground beneath 
their tree, and against whom their angry outcries were directed.

Seymour, Tower, and Wenman islands. 
Generally distributed and exhibiting considerable variation 
on different islands, this species was seen more or less com- 
‘monly on all of the above islands, except Culpepper, Daphne, 
and Duncan. On the last-named island I saw one in the 
south crater on August 14, my attention being attracted by its 
continual chirping. On Daphne I saw one, July 25. None 
were seen on Culpepper. 
Black-eared Mockingbirds were found in all the life zones 
from the seashore to the mountain top, with one exception,
