season the White Foxes live almost exclusively on Murre’s eggs and they 
are very adept at scaling the cliffs for them. Sometimes they bury the eggs 
in the tundra back of the cliffs and eat them later in the year. 
[Stercorarius longicaudus. Lona-Trartep JAmEGER.— One shot on 
Hall Island on July 14, 1899, had a Meadow Mouse (Microtus abbrevia- 
tus), in its gullet, and the remains of another in the stomach. (A. K. F.)] 
Rissa tridactyla pollicaris. Paciric Kirrrwake.— Colonies of a 
hundred to a thousand were found at various places on the cliffs. Sub- 
stantial nests are constructed of grass and moss in places which are usually 
just out of reach. The smaller Red-legged Kittiwake was closely watched 
for but was not seen after leaving the Pribilofs. 
Larus hyperboreus. Guaucous Guuu.— This is the only member of 
this genus found nesting on the reservation. The Glaucous-winged Gull 
may occur occasionally even in mid-summer but it was not noted by me at 
any time after the Pribilofs were out of sight. The big white Burgomaster 
was constantly seen while we were about St. Matthew and Hall Islands, 
either scouring the beaches for carrion or hunting the cliffs for Murre’s 
eggs. It builds its nests of matted grass and moss and keeps a very filthy 
house. Considerable sagacity is shown in placing the nest in an inaccessible 
place, usually offshore on outlying rocks which can be scaled neither by 
man nor fox. One of these however I was able to climb and found on top 
about 100 nests, one third of which were being occupied. The young, 
(black speckled balls of white down), were just appearing on July 10 and 
were just a little ahead of the cormorants. Around each nest were found 
quantities of the shells of Murre’s eggs and the same were found in the 
stomachs of those birds examined. ¥ 
St. Matthew Island marks the southern breeding limit of this species in 
the Bering Sea Islands, save fora small colony on Walrus Island of the 
Pribilofs, the Glaucous-winged Gull being the common breeding species 
of the Pribilof group. In fall and winter both species move southward and 
both are found on St. Paul throughout the fall. In the coldest parts of 
the winter the Glaucous Gull only is found there. 
[Xema sabini. Sasiny’s Guiy.— Two specimens, now in the Biologi- 
cal Survey collection, were secured from a flock of five on July 15, 1899. 
They were fishing off-shore in company with Rissa and Larus. (A. K. F.)] 
[Sterna paradisea. Arctic TerN.— Observed about the islands on 
at least one occasion, July 14 or 15, 1899. (A. K. F.)] 
Fulmarus rodgersi. RopGer’s Futmar.— This is one of the most 
abundant birds found breeding on St. Matthew. On every cliff there were 
very large colonies. Among all the many thousands of birds seen here 
not one of the dark phase was noted. The single white egg is placed on 
any kind of a ledge which is large enough for the bird to sit upon. 
Phalacrocorax pelagicus robustus. VIOLET-GREEN CoRMORANT.— 
No other Cormorants except this species were found on the reservation 
although a careful lookout was kept for the Red-faced. Nests were found 
on almost every cliff and they were especially abundant about the south
