320 CHESTNUT-SIDED WARBLER 



for this, he seemed calm and self-possessed through 

 all her persecution, hopping from twig to twig, 

 running along the branches, clambering up the 

 stalks of the bushes, and occasionally giving a 

 thin low call; while she flashed around madly, 

 under leaves and over branches, flying up against 

 one tree trunk only to dart off to another. At 

 first she made no noise, except when she snapped 

 her bill ; but later on she sang a few notes now 

 and then while at her work. 



The next day the young flew ; but though the 

 Chestnut watched where the Redstart went and 

 tried to follow her, after he had been driven back 

 a number of times he apparently gave up ; at all 

 events he disappeared. 



Whether he finally succeeded in following the 

 family, or went away discouraged in well-doing, 

 we did not determine. We saw the Redstart 

 hunting about in the vicinity of the dead treetop 

 where she took her young, the day after they left 

 the nest, but saw no more of the Chestnut with 

 her.
