Pisobia minutilla (Vieillot). Least Sandpiper

Seen at Carcross May 22. At Atlin the first south-bound migrants
appeared June 29, when two single adults were seen at different points.
One of the birds was performing the usual mating flight. A few days
later small flocks began to drop in at intervals, continuing until
August 27, when the last was seen. ;

Ereunetes pusillus (Linnaeus). Semipalmated Sandpiper

A single bird, a south-bound migrant, was collected at Atlin,
July 17. This specimen (no. 44649) is an adult female, in which the
annual molt has just begun. Two were seen at close range on the shore
of Morley Bay, Lake Teslin, September 12.

Totanus flavipes (Gmelin). Yellow-legs

Present in some numbers at Carcross, May 22, and evidently then
preparing to nest. The birds were in pairs and noisy and solicitous at
any invasion of their territory. Some were going through the nuptial
flight and ‘‘song,’’ some perched on tree-tops scolded the intruder.
About Atlin there were yellow-legs in nearly every lowland swamp.
While the breeding birds were thus distributed in pairs over the
country, there were also wandering flocks that appeared at intervals
during June and July. These were evidently composed of non-breeding
individuals.

We found no nest, but Brooks collected a newly hatched chick on
June 17. The downy young had the faculty of remaining invisible,
or nearly so, but when almost full grown they became conspicuous
about the edges of the ponds, and were then indifferent to approach.
By July 20 the yellow-legs had nearly all left for the south; the last
birds were seen August 13 and 14.

Three specimens were collected by me, young nearly or quite full
grown (nos. 44650-44652).

Tringa solitaria Wilson. Solitary Sandpiper

First seen at Carcross, May 25. Early in June the species was
encountered not uncommonly about Atlin, and the birds seen had all
the appearance of being upon their nesting grounds. Individuals were
going through their courting flight and song overhead, and some were
