1 1 o American Birds 



the parents care for them a week or so after they leave 

 the nest till they are able to hunt a living for themselves ; 

 then the family scatters and loses identity in the great 

 world of feathers. Not so with the bush-tits: they hunt, 

 feed, and sleep together, winter as well as summer. Such 

 little talkers ! They titter as much as they hunt and eat,
