Genus TACHYCINETA Cab. 



White-bellied Swallow, natural size. 



257-614-(160). Tachycineta bicolor (Vieill.). *Tkee Swallow; White-bellied 

 Swallow; Blue-backed Swallow; Field Swallow. 



Very common; throughout the state; March or April to August; " common at Iron 

 Mountain" (E. E. Brewster); "Keweenaw Point" (Kneeland); breeds; often two broods; 

 nests in May and June, in hollow istumps or holes in trees or buildings, " often in stubs 

 in or near water " (Dr. W. C. Brownell); eggs four to seven, occasionally 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. 



Genus CLIV1COLA Fokst. 



258-616-(163). Clivicola riparia {Linn.). *Bank Swallow; Sand Swallow; 

 Sand Martin. 



Very abundant; throughout the state; May to August; "Mackinac Island" (S. E. 

 White); breeds abundantly; nests in May in sand banks; A.B. Covert, of Ann Arbor, 

 once saw it nesting in a crevice of a building (does not Mr. Covert's note refer to the 

 next species?); eggs five or six, white; these birds are very amiable, never seen quarrel- 

 ing; " I have found three nests in branches of one hole" (Dr. W. C. Brownell); Mr. 

 Robt. M. Wolcott saw at White Lake, Muskegon County, July, 1891, an immense 

 colony, numbering hundreds. The bank was very sandy and several nests had a com- 

 mon vestibule near the face of the bank. 



Gencs 8TBLGIDOPTERYX Baibd. 



259-617-(164). Stelgidopteryx serripeunis (Aud.). * Rough- winged Swallow. 

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

 Bank Swallow. He adds further that this bird often builds in crevices in bridges, etc.
