Nests in Holes in Trees, Stumps, or Logs 
him, a pet one, but three months old, is sitting on my paper, 
seeming to wonder what I am doing, and why I do not play with 
him. He nips my pencil, but I pay no attention to him ; then he 
tries to creep up my sleeve, and still | pay no attention ; so, dis- 
gusted, he flies off to search for ants or other small insects. After 
a time I raise my hand and call ; back he comes like a flash, and, 
hovering more like a large moth than a bird, he perches on my 
fingers, singing at the same time a soft little song that is his 
method of speech. Having a bird that is so thoroughly com- 
panionable makes me regard all bluebirds with the greatest pos- 
sible affection. 
Near New York the breeding season begins early in April ; 
two broods are reared during the season. The young remain in 
the nest until about fifteen days old. It is noticeable that their 
claws are exceedingly sharp ; this is, in all probability, that they 
may be able to climb out of the hole in which their nest is placed.
