An-ives as early as February 27th; becomes common by 

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

13. Regulus calendulus, Light. — Rnhy-crowned 

 Kinglet. Common spring and autumn migrant. Arrives, 

 in spring, from April 10th to 22d; remains vmtil the first 

 week in May ; arrives from the north the second, and de- 

 parts south the last, week in October. Found in the woods

U. 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 caeridea^ Sclat.) 

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



PARID.E, — The Titmice. 



^ 15. Parus atricapillus, Lixx. — Blach-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.E, — The Creepers. 



16. Certhia familiaris,* Linn. — Broivn 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 ^ 

 synonyme.
