mouth, and knew from his actions that his nest was near. He acted just as 

 did the other one, going to the nest by diving downward when a few rods 

 away from it and then cither creeping or tiying low down into the nest. 

 The cover was so thick i could not hnd out which method was used. 1 

 often saw these birds light on the ground, and think them to be as ter- 

 restial as Dcndroica palmaruiii. However, 1 soon Ihished the female from 

 the ground and very carefully located the spot, but it was so completely 

 covered with shrubs and plants, that only by parting them could I see the 

 nest, which was built exactly like the lirst, only one half inch deeper and 

 wider, and more cup-shaped, with the edges incurved, especially at the 

 rear. This nest contained live young about ten days old. The number of 

 eggs in a set is perhaps three to live. This pair of birds was shy and it was 

 difficult to get a snap-shot of them. I spent the day in watching them and 

 in taking notes on habits, song and habitat. 1 also made a list of the birds 

 that live with them. This list will be published later. The junco is common, 

 and breeds, as is shown by the occurrence of young. 



On the morning of July loth i walked two miles west of North branch 

 in search of the warblers, and found the conditions different. The plains 

 are here wooded with older jack pines. 'J'he food of this warbler seemed to 

 be span-worms, living upon jack pines, and a small light-colored span- 

 worm moth (Diastictis inccptata, Walk.). 1 saw the warblers capture these 

 moths during flight. 1 also shot a male Kirtland that came to nest No. :l 

 with a deer fly in his mouth, so that flics and other insects, as well 

 as the span-worms may compose their foqd. I consider the 

 North branch the western boundary of this colony of Kirtland's 

 warbler, but on describing the bird, its food and its habits to a young man 

 who lives a few miles north west on the North branch, he said the birds 

 were there and were called ''the jack pine bird." T consider this a very 

 appropriate name, as most of their time is spent on these trees and the 

 bulk of their food is gleaned from them. Tt is not, however, every jack 

 pine plain that is the home of a colony, as T examined himdreds of acres 

 where the conditions seemed all right, and found none. 



In the afternoon I went to nest No. 1 to make, if possible, more observa- 

 tions upon the home life of these birds. I found the parents at home, the 

 male singing, as usual, although he seems to share equally with the female 

 the care of the young. I heard his chip chip chc che chcc a a repeated at 

 short interxals, from fifty to sixty seconds. I And these birds very quick 

 and restless, with a direct, slightly undulating flight. When they go from 

 their perch on a tree or stub, they seem to dive down, and while perching 

 and feeding have a short, jerky motion of the tail. I watched them for 

 hours, gleaning worms from the low jack pines, very often jumping from 

 a limb to fly a few feet and catch a moth or fly on the wing, always return- 

 ing to the same tree or stub to rest or sing before dropping down to the 

 nest to feed the young, apparently always approaching the nest from the 

 same direction, as there was a path beaten only on one side, and the young 

 T always found facing in that direction. 



On the morning of July 11th I secured a male, but could not find the
