^^. Birds of Massachusetts 



256. Mimus polyglottos (Linn.). Mockingbird. 



A very rare summer resident. It has been found breeding at Tat- 

 ham and Springfield,^ at Arlington/ at Marshfield,3 and at Groton ; * 

 and probably at Hyannis,^ where a young bird in spotted plumage 

 was taken August 30, i89i,at Ipswich,^ where a pair were taken on 

 April 4, 1892, and at Highland Light,' where three birds were 

 seen September 11, 1890. In addition to the above, two adult 

 females have been taken at Taunton, April 5, 1893,* and Novem- 

 ber II, 1897,^ respectively. The many other birds recorded may 

 be either escaped cage-birds or actual visitants from the south, so 

 that such records are valueless. 



257. Sialia sialis (Linn.). Bluebird. 



A common summer resident, more numerous on migrations. 

 On Cape Cod it winters somewhat regularly in small numbers, 

 and has been found in winter at various other points near the 

 coast.
