appeared. By the last week of June the crossbills were in pairs,
apparently preparing to nest, but soon after their numbers lessened
until relatively few remained. Two specimens were collected, both
adult males (nos. 44801-44802).

Spinus pinus (Wilson). Pine Siskin
Arrived at Atlin toward the end of June. First noted June 25,
and became fairly numerous by the middle of July. At the time of
my departure, September 23, siskins were still present in numbers.

Calcarius lapponicus alascensis Ridgway. Alaska Longspur

At Carcross, May 23, the cat at the hotel where we stayed brought
in a longspur, which we were able to identify from the feathers
seattered about. This, presumably, was a belated north-bound
migrant. The species was next encountered on September 1, when
I flushed several high upon the mountain above ‘‘Blue Cafion.’’ On
September 7 several large flocks were observed between Surprise and
Gladys lakes.

Passerculus sandwichensis alaudinus Bonaparte.
Western Savannah Sparrow

When we reached Atlin, May 28, Savannah sparrows had already
arrived, and the male birds could be seen singing from low perches
in the more open swamp-land. The species was not common, but a
few pairs were scattered through the wet meadows that partly encircle
the town of Atlin, and small numbers were seen elsewhere, where
suitable conditions obtained. On June 25 a nest was found, containing
six eggs on the point of hatching. The nest was sunk in the ground,
in marsh grass, with no trees or bushes in the near vicinity.

On September 1, Savannah sparrows were seen in numbers, migrat-
ing, on some of the higher, more open, mountain slopes. The last bird
was seen September 21. Three specimens were collected, an adult
male, and male and female in first winter plumage (nos. 44803-44805).

Zonotrichia gambelii (Nuttall). Gambel White-crowned Sparrow
An abundant summer visitant to the lowlands of this region. At
Careross when we arrived, May 22, the Gambel sparrows were already
paired and preparing to nest. The first nest was found at Atlin on
