on the hillsides, on the ground generally, under the lee of a stone. 
Obtained many of these birds at Nulato, in the winter of 186Y-8. It is 
much more common there than P. lapponicus, which was only seen in 
the spring, while this species is abundant the year round. 
It was also obtained by Bischoft" at Sitka, and by myself at St. George's 
Island. The specimens from the last named locality have a yellowish 
appearance on the breast, which I have not noticed in any Yukon speci- 
mens. Indian name " hokohyzoa^'' or " little white bird." D. 
This species is altogether less abundant than the P. lapponicus, and, 
as far as I observed, seemed to prefer rather different situations. On 
St. Michael's Island, I never noticed one of this species far from the sea 
shore, while the other species was abundant every where over the mossy 
tundra of the interior of the island. During the summer, I never saw 
this species in greater numbers than one or two together, nor any where 
except near rocky points, and on some of the small rocky islands a little 
off shore, which they seemed to share with tiie ravens and puffins. In 
the autumn, however, they are more gregarious, but still seemed to 
j)refer the vicinity of the water. I have followed a small flock for 
upwards of a mile along the beach, they following all the indentations 
of the shoi'e, flying short distances at a time, but just keeping at long 
gun-shot. In general, however, this bird can not be called shy. I have 
observed this species at Unalaklik, where it is common. B.

Arrives at Nulato about May 12th, and is not at any time a very common 
bird. Did not find the nest during my stay at Nulato; was informed by 
tlie Indians that it built on the bare hillsides, in hillocks of grass, and 
will not leave the nest when any one comes near, but sits perfectly still, 
thus often escaping discovery. A fine singer. Received from Sitka 
through Bischoff. D. 
By far the most abundant of the land birds which are found on the 
Island of St. Michael's. It appeared there first about the 6th of May, 
and from that time until the middle or latter part of September was 
observed in great numbers over the island. 
I did not find the nest, although the birds were started up by the 
hundred on every walk over the island, I therefore think that it must be 
very carefully concealed. I often searched for it, but always with the 
same want of success. This species is, in my opinion, decidedly the best 
songster of the family. B.
