Rosy Gull and the Pectoral Sandpiper. 571 
full particulars respecting the nesting-habits and the young 
in down of Rhodostethia rosea, and it is therefore unnecessary 
to repeat them here ; with regard to the Pectoral Sandpiper, 
however, he has sent me voluminous notes respecting the 
nesting-habits and young in down, from which I have 
extracted the following details.—H. E. D.] 
Tue Pectoral Sandpiper (Tringa maculata) was first noticed 
by me on the 29th of May, 1905, at the earliest appearance of 
the Arctic spring, as I was siowly making my way with tired 
and hungry dogs from the Great Baranoff Cape westward to 
the mouth of the Kolyma, on the sea-ice. It appeared in 
flocks of from twenty to forty individuals, flying swiftly in 
one continual line from the east, uttering a somewhat harsh 
call, ‘‘ twee, twee, twee,” or “ teeleé, teeleé, teeleé,” or, when 
alarmed, “ ¢eer, leer, leer, lee.’’ 
During the last days of May and the first days of June 
it was very numerous near Pokhodskoe on the portions of 
the low islets where the old grass was already free from 
snow. Single birds were very hard to flush, and when they 
rose uttered a “ cheep, cheep, cheep,” and a whistling note not 
unlike that of a Snipe; but the majority of the birds were in 
flocks of from ten to a dozen individuals, and though some- 
what shy were by no means difficult to approach within 
gun-range, while, the cover being scanty, I could observe 
them well with my powerful binoculars. They would fly 
from one place to another in parties, and run swiftly, like 
so many mice, here and there in the old grass. One would 
every now and then stretch both wings right over its back, 
and afterwards commence a grotesque sort of dance, hopping 
alternately on each leg; another would inflate its gular 
pouch and run about, crouching down to the ground, or 
would fly up to about a hundred feet in the air, then inflate 
its pouch and descend slowly and obliquely to the ground on 
extended wings, All these performances were accompanied 
by a strange hollow sound, not very loud when near, but 
audible at some distance, even as far as five hundred 
yards. These notes are very difficult to locate, and vary
