notes being somewhat similar. Though these nuthatches paralleled our 
White-breasted type, even to the chestnut undertail-coverts, yet they had 
a black eye-streak and grey crowns. Both skulls were about half granu- 
lated; the two were probably from the same brood. Probably the small 
nest-hole — -now demolished — that was seen in a willow trunk up on the 
hill, had been pecked out by a nuthatch bill, as no woodpecker had been 
seen there.”

Much like our Sitta carolinensis , but with a black patch through the eye and the crown con- 
colour with back.

Not uncommon in the birch woods around Petropavlovsk and also 
seen in the stunted alder tangles of the high hilltops. When first seen, 
July 22, they were in family groups. The notes of these birds resemble those 
of the Hudsonian rather than the sprightly Black-capped American 
relative.

A very beautiful chickadee, like our Black-capped, but the lights very white.

On March 15, in some trees near the wharf at Cordova, the notes of 
a chickadee were heard plainly, but the bird could not be seen.

At Petropavlovsk this little skulker was found in the low shrubbery 
on the more open country. It was fairly common. As it was not heard 
in song its numerical status could hardly be determined. The only note 
heard from it was a wren-like “Chak!” and the only way it could be secured 
was by lying down or crouching very low and squeaking, at which it would 
mount to the tops of the low cover.

For some days after our arrival at Petropavlovsk, an elusive song of 
good quality was heard in the birch woods, but the author could not 
be seen. When a breeze was blowing, the twinkling leaves of these 
trees made it most difficult to catch sight of birds aloft in the upper
