40 THE BIRDS OF SPRINGFIELD AND VICINITY. 



749. Regulus calendula (I/inn.). RUBY-CROWNED 

 KINGLET. Common spring and autumn migrant. 



751. Polioptila caerulea (I, inn.). BLUE-GRAY 

 GNATCATCHER. Accidental visitor ; one was taken at East 

 Hartford, September 21, 1885 (see Auk. Vol. 3, page 487). 



755. Hylocichla mustelinus Gmel. WOOD THRUSH. 

 Common summer resident. 



756. Hylocichla fuscescens Steph. WILSON'S 

 THRUSH. Common summer resident. 



757. Hylocichla aliciae (Baird). GRAY-CHEEKED 

 THRUSH. Rare late spring and early autumn migrant. I pre- 

 sume the Bicknell's Thrush occasionally occurs here during 

 its migration, but I have no proof of that fact. 



758. a Hylocichla ustulatus swainsonii (Cab.). 

 OLIVE-BACKED THRUSH. Common migrant ; no doubt that it 

 occasionally, but rarely, breeds in some of the mountain towns 

 in the extreme western portion of Hampshire county, as it 

 does just beyond in Berkshire. 



759. b Hylocichla aonalaschkae pallasii (Cab.). 

 HERMIT THRUSH. Common migrant and rare summer resi- 

 dent in Chester, Middlefield and Worthington, but at no 

 season as numerous as it was previous to 1895, when so many 

 were destroyed by the severe cold at the South. 



761. Merula migratoria (I,inn.). AMERICAN ROBIN. 

 Abundant summer resident, occasionally winters. 



766. Sialia sialis (I/inn.). BLUEBIRD. Abundant 

 summer resident ; I have seen it here every month in the year 

 but January. Rev. William B. O. Peabody, in the report of 

 the Ornithology of Massachusetts, which he wrote at his home 

 in Springfield, spoke of the appearance of the bluebird in 

 January, 1838 ; whether he meant here or elsewhere in Massa- 

 chusetts, I cannot say.
