completed in seven days and the first egg laid, and an egg 

 daily until the set of three was complete. The nest was com- 

 posed of hornet's nest paper, bits of birch bark, and small 

 lichen fragments, held together with spider webs, and lined 

 with fine grass culms. It measured two and a half inches deep 

 outside by one and a half inside, the external diameter was 

 three and the diameter inside two inches. The three eggs 

 measured 0.89 x 0.63, 0.86 x 0.63, 0.85 x 0.60 and were white 

 with a few black, reddish brown and umber specks about the 

 larger ends. This nest contained eggs on June 29, 1894. 

 The nesting season is rather late, the eggs, three or four in 

 number, being laid from the middle of June to early July. 

 Incubation requires twelve to fourteen days. 



The food consists largely of insects which are gleaned from 

 the foliage and limbs of the trees as the birds hop through the 

 branches or climb about the ends of the limbs. Occasionally 

 I have seen them spring into the air after some passing insect. 

 Various beetles, green caterpillars, spiders, hymenopterous 

 insects, moths, lice, eggs of insects and similar things are 

 eaten. Occasionally a few wild cherries and shad bush fruit 

 are eaten but the diet is in summer largely insects.
