BIRDS OF MASSACHUSETTS 



256. Mimus polyglottos (Linn.). MOCKINGBIRD. 



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

 ham and Springfield, 1 at Arlington, 2 at Marshfielcl,3 and at Groton ; 4 

 and probably at Hyannis, 5 where a young bird in spotted plumage 

 was taken August 30, 1891, at Ipswich, 6 where a pair were taken on 

 April 4, 1892, and at Highland Light, 7 where three birds were 

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

 females have been taken at Taunton, April 5, 1893, 8 and Novem- 

 ber ii, 1897, 8 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.
