Actitis macularia (Linnaeus). Spotted Sandpiper. 
Seven examples of Actitis macularia were taken: an adult 
and a downy youne (Nos. 154, 155) from Port Frederick, Chi- 
chagof Island, July 27; four adults from Glacier Bay (Nos. 176- 
179), and one from Hasselbore Lake, Admiralty Island (No. 
170). A eareful comparison of Alaskan specimens with a series 
from the Atlantic States, shows no differences that I can dis- 
cover. Besides the above-mentioned localities, the species was 
observed in pairs at Hasselbore, Alexander, and Beaver lakes, 
Admiralty Island. This was between May 19 and June 11, so 
they were doubtless nesting there. According to Dixon, a pair 
evidently had eggs or young near a stream at the head of Idaho 
Inlet, Chichagof Island, July 20 to 25. At Glacier Bay, July 
16, Littlejohn saw a young spotted sandpiper, but it escaped in 
the grass. At Coppermine Cove, on the west side of Glacier 
Bay, Dixon secured a set of four half-incubated eggs with the 
female parent, July 14. The nest was a sheht depression in the 
surface of a gravel patch and was shaded by three small willow 
sprouts that happened to grow close together. The nest was 
lined with dry dead willow leaves. ‘‘The female had a way of 
sneaking off the nest without uttering a note. She would run 
about twenty feet and then fly silently away.’’ The eges of the 
set are heht clay color, spotted and blotehed with dark shades 
varying from burnt umber to ecru drab. They measure: 33

Aegialitis semipalmata Bonaparte. Semipalmated Plover. 
At Windfall Harbor, Admiralty Island, May 8, a pair of 
this species was seen on a sand flat by Dixon. At Glacier Bay, 
July 5, Littlejohn found a considerable number on a wide gravel 
flat near the head of a long inlet. He believed them to be breed- 
ing there; yet no nests or young unable to fly were discovered. 
The species was seen on subsequent days at different points on 
Glacier Bay; four adults (Nos. 96-99) in worn breeding plu- 
mage (though probably migrants) were taken July 5, 6 and 17.
