KITTIWAKE. 
The Kittiwake is a regular spring and fall migrant, spend- 
ing its winters far to the south, returning here from the 25th 
of March to the 10th of April, remaining for only about eight 
or ten days, and then passing on further north to breed. Cir- 
cumstances connected with my observations of the gulls 
migrating through the portion of the State where my principal 
personal observations have been made, lead me to believe that 
this species breeds on the islands of a number of our northern 
lakes. I hope to be able to settle many facts in connection 
with the gulls in the near future, which it has been impossi- 
ble to do up to the present time. The young may be seen at 
Bigstone lake, Mille Lacs lake and along the Red river as 
early as the 15th of August in ordinary seasons, and always 
the last week in October, in considerable numbers. As the 
Kittiwake Gulls are known to breed ‘‘as far south as Bird 
Rock, in the Gulf of St. Lawrence” (Langille) there can be no 
valid reason to doubt their doing so in the vicinities referred 
to in Minnesota. Their food while with us consists of fish, 
molluscs, aquatic larve, and small water snakes. 
Samuels (Birds of New England) says, ‘‘The nest is com- 
posed of seaweeds arranged in a large pile, and placed ona 
ledge of rock in a crevice, or on a jutting shelf, and is occupied 
for successive years, receiving additional material every year. 
ne eggs are three in number. Their form is ovoidal; the 
color varies from a creamy drab, with a very slight olivaceous 
tint to a delicate gray. On this are scattered blotches of
