Warbler literal!}' abounds, and its song is constantly heard. 

 This seems to nie to differ from most warbler songs, being more 

 energetic, after the manner of the Geothlypis group than like 

 the drowsy Dendroica nuisic. 



With them occur the Redstarts and the Juncos. The latter 

 are particularly common, and breed in various situations, but 

 chiefly along the trails and pathways. All through the wood- 

 land, but especially near the streams, are the Chickadees, giv- 

 ing vent to their feelings in their pleasing, familiar whistle, and 

 with them occurred now and then a song that we could only 

 identify with the Tufted Titmouse. We could not trust our 

 ears when we first heard it, but closer observation proved that 

 we were correct. I am at a loss to account for the presence of 

 this Carolinian species in this Canadian environment, but sup- 

 pose it entered from the upper Delaware valley not many 

 miles awa}', and, as has already been said, present conditions 

 favor the advance of southern birds and the retreat of boreal 

 ones in the Pennsylvania forest area. 



Four other Warblers besides those already mentioned were 

 seen by our party : the Yellow Warbler, abundant in orchards 

 and open willow thickets along the streams ; the Maryland Yel- 

 lowthroat in its usual haunts ; the Golden-winged Warbler, 

 evidently rare, as only one was seen, and the Yellow-breasted 

 Chat. The last is another southerner which probably reached 

 this section by the same route as the Tufted Titmouse. In the 

 same scrub-land where we noticed the Chat, the Brown Thrasher 

 and Catbird were common, especially the latter. 



One species remains whicli we found frequently in the hem- 

 lock woods, the Solitary Vireo. Its song is really beautiful, 

 and justice has not been done to it. One nest was found in a 

 hemlock some five feet up. The female sat vcrj' close, but 

 would not let me touch her. The Solitary Vireo is found 

 especially common in the swampy sections of the forest, where 

 the song might be called a feature. 



In the same locality the Winter Wren is seen, but is by no 

 means common. His cousin, however, the House Wren, was as 

 abundant as usual about the village, where also we found the 

 Warbling and Yellow-throated Vireos, both rare, and the Rose-
