HETERACTITIS INCANUS (Gmelin). 
WANDERING TATLER. 
We did not find this species and only brought back two purchased 
specimens, both females taken at Copper Island, on May 17 and 21, —. 
ACTITIS HYPOLEUCUS (Linné). 
COMMON SANDPIPER. 
The collection contains the skin of a male taken at Copper Island, 
May 24,—. Purchased. 
TRINGA GLAREOLA Linné. 
WOOD SANDPIPER. 
One pair was taken at Cape Zhipanov, Kamchatka, May 25, 1913. 
The purchased collection contains two males taken at Copper Island, 
May 19, —. These birds agree absolutely with western specimens. 
EREUNETES PUSILLUS (Linné). 
SEMIPALMATED SANDPIPER. 
Between Collinson Point and Herschel Island this is a common bird. 
It was common at Collinson Point, on August 3 and 9, 1913. A few 
were seen at the delta of the Hula-hula River, August 11, 1913. 
At Demarcation Point it is a common summer resident, the first 
arrivals coming May 22. On that date I saw three, and shot two 
which proved to be males. By May 27 they were common. 
Most of these birds seemed to be paired on arrival, and could be 
found about pools or on the comparatively dry tundra. 
Thirteen nests were found, the first, a set of three fresh eggs being 
taken on June 12. All the nests were essentially alike — mere cavities 
in damp tundra close to a pool, and lined with dry willow leaves. On 
seven nests the female was found, and ‘the male on six. Although the 
male seems to take about an equal share in brooding on the eggs and 
taking care of the young I could not see that he did this at any particu- 
lar time for I would find either sex on the nest at midnight or midday.
