BIRDS OF EASTERN MASSACHUSETTS. 
93 
Arrives as early as February 27th; becomes common by 
March 10th; leaves about the 1st of November. 
SYLVIIDiE, — The Warblers. 
13. Regulus calendulus, Light. — Eicby-crowned 
Kinglet. Common spring and autumn migrant. Arrives 
in spring, from April 10th to 22d; remains until the first 
week in May ; arrives from the north the second, and de- 
parts south the last, week in October. Found in the woods 
and orchards everywhere. 
14. Regulus satrapus, Light. — Golden-crowned King- 
let. Abundant winter resident. Found everywhere. Have 
taken it from October 14th until May 9th. Commonly 
seen in company with the Chickadee. 
The Blue-gray Gnatcatcher [Polioptila ccerulea^ Sclat.) 
is said to occur. I have never met with it in this section. 
PARIDiE, — The Titmice. 
15. Parus atricapillus, Linn. — Blaclc-capped Titmouse, 
Chickadee.’’ Abundant resident. Found everywhere ; 
no bird is better known. Builds its nest by drilling a hole 
in a partly decayed tree, generally a birch. It sometimes, 
however, occupies other holes in trees. It builds its nest 
about the first of May. 
CERTHIID^, — The Creepers. 
16. Certhia familiaris,* Brown Creeper. 
Resident. Rather rare during summer, but common in 
winter. Found everywhere, — in the woods, in orchards, 
* The supposed difference between the American and European Certhia 
is not tangible, therefore the specific name of Americana becomes a 
synonyme.
