TENNESSEE WARBLER. 



A O U No. 647. Helminthophila peregrina (Wils.).

General Range. — Chiefly Eastern North America but also west to Rocky Mts. and 

 beyond (northerly), breeding from northern tier of states north to high latitudes; south 

 in winter to eastern Mexico, Central America and United States of Colombia. 



Occurrence in British Columbia. — In the season of 1901 I found this species unex- 

 pectedly common in the vicinity of 158-Mile House in the Cariboo district. The birds made 

 their first appearance on the 22nd of May and became common the same da.v. From that 

 time on I heard their song in almost every clump of trees. A great number of them drew 

 ofif to northward but a good many remained. They generally frequented the clumps of 

 aspen trees and Murray pines where the ground was covered with a thick growth of dry 

 pine-grass. 



As I saw no females nor evidence of nesting I gavf the birds three weeks and started 

 out to look for their nests on the 15th day of June. Luckily I soon found a female ofT her 

 nest, and after an hour's watching, during which I suffered torments from the mosquitoes, 

 she at last dropped down to the nest. 



Examination disclosed four eggs of a creamy white color finely speckled all over the 

 surface with reddish-brown and with some larger spots of the same color. There were 

 also some spots of light lilac but these were not conspicuous. 



On the same day two more nests with newly-hatched young were foiuid and several 

 more, also with young, were encountered the week following. 



The nests were always on the ground, sometimes at the foot of a small service-berry 

 bush or twig. They were all arched over by the dry pine-grass of the preceding year; this 

 year's growth having just commenced. The nest is small even for a warbler, shallow and 

 of loose construction. It is composed externally of a few dead leaves, a little moss and a 

 good deal of fine grass with a lining exclusively of the last-named material.
