THE SMALL GREEN-CRESTED FLYCATCHER. 143 



was off the nest, he was very pugnacious ; attacking every 

 bird that came near, and even forcing a robin to retreat, so 

 fierce was the onshxught lie made on it. He always, in 

 attacking other birds, uttered his shrill cry, cliehec, chebee, 

 and snapped his bill loudly and fiercely. AVhen perching, 

 he often flirted his tail in the manner of the Phebe ; and, 

 every few seconds, he emitted his note, — chebec, chebee, 

 chebec; varied sometimes into chebec-trree-treo, chebe c-treee- 

 cheu. 



The young were all hatclicd by the fourteenth day, and 

 left the nest within a month from their birth. They were fed 

 abundantly, while on the nest, by the parents, with insects, 

 which they caught and crushed between their bills : they 

 were fed a few days after they left the nest, and then turned 

 adrift ; the parents having begun another nest on the same 

 tree. 



The Least Flycatcher has often been called the Small 

 Green-crested or Acadican Flycatcher. I would caution 

 those who are interested in the history of these birds to 

 observe great care, and be certain of their identity before 

 naming them. 



By the second week in September, it leaves on its south- 

 ern migration.
