Arrives as early as February 27th; becomes common by 

 March 10th.; leaves about the 1st of ..November. 



SYLVIID^E, THE WAEBLERS. 



13. Regulus calendulus, LIGHT. Ruly-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 coerulea, Sclat.) 

 is said to occur, I have never met with it in this section. 



PARID^E, THE TITMICE. 



15. Parus atricapillus, LINN. Slack-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. 



CERTHIIDyE, THE CREEPERS. 



16. Certhia familiaris,* LINN. 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 9* 

 synonyme.
