sionally nine, white. I have taken several nests from hollow stumps, and always 

 found them lined with pure white feathers, many of which were too large to have 

 come from this bird. "Arrives at Bay City from April 4 to April 16'' (N.A.Eddy).

Very abundant; throughout the state; May to August; "rather common at Albion 

 and exceedingly abundant at St. Joseph where flocks of thousands are often seen 

 in August" (O. B.Warren); "breeds extensively at Mackinac Island " (S.E.White); 

 breeds abundantly; nests in May in sand banks; "very common at Port Sanilac 

 where it breeds in colonies along the lake shore'' (W. A. Oldtield); "no suitable 

 breeding places at Bay City" (N. A. Eddyj; eggs five or six, white; these birds 

 are very amiable, never seen quarreling; "1 have found three nests in branches of 

 one hole" (Dr. W. Bi-ownell); Mr. Robt. H. Wolcott saw at White Lake, Muskegon 

 Co., July, 1891, an immense colony, numbering hundreds. The bank was very sandy 

 and several nests had a common vestibule near the face of the bank.

Rather common; "in the southern part of the state" (Prof. J. A. Allen); Mr. S. 

 E. White reports finding a dead specimen at Mackinac Island in July, 1890; May 

 to August; nests in May. in sand banks, or "buildings or crevices in stone walls" 

 (A. W. Butler); eggs and food habits much as in bank swallows. Dr. Gibbs informs 

 me that the opening to the nest is circular, and not eliptical as it always is in the 

 case of the Bank Swallow. He adds further that this bird often builds in crevices 

 in bridges, etc.
