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

 Id. Abundant winter resident. Found everywhere. Have 

 taken it from October 14th until May 9th. Commonly

The Blue-gray Gnatcatcher (Polioptila ccerulea, Sclat.) 

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

15. Parus atricapillus, Linn. — Blachcapped Titnwuse, 

 "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. 



CERTHIIDiE, — The Creepers. 



16. Certhia familiaris,* Linn. — Brovm Creeper. 

 Eesident. Kather 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 Americcma becomes a 

 synonyme.
