66 MICHIGAN BIRD LIFE. 
some individuals remain throughout the year, although the majority 
move southward during the winter, at which season they are not un- 
common along the Maine coast and even somewhat farther south. 
Inland records at any season are rare and there are but one or two 
records (and these not perfectly authenticated) for the Great Lakes. It 
is therefore with much pleasure that we are able to record the capture 
in Michigan of a fine specimen of this bird and its preservation in the 
University Museum at Ann Arbor. This bird, an immature female 
in the white-spotted brown plumage, was shot October 19, 1911, by Mr. 
J. P. Case, on a small lake in Hamburg township a few miles north of Ann 
Arbor. Mr. Norman A. Wood of Ann Arbor, to whom we are indebted 
for the record, states that when first observed the gannet appeared to 
be asleep, since it was resting with the head hidden beneath the wing 
in the manner of a domestic goose. Evidently it was weak from lack 
of food if not from fruitless wandering. 
Gannets nest always in communities, and build bulky nests of seaweeds 
on ledges and shelves of almost inaccessible rocks. The largest and best 
known nesting grounds in this country are on the Bird Rocks in the Gulf 
of St. Lawrence, but the species formerly nested on one or more islets 
off the coast of Maine. Only a single egg is laid, which is at first pure 
white with a thick chalk-like shell which soon becomes soiled and stained 
by the feet of the bird and the materials of the nest. The egg measures 
about 3 by 1.92 inches.
