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 onslaught he made on it. He always, in 
attacking other birds, uttered his shrill ery, chebéc, chebéc, 
and snapped his bill loudly and fiercely. When perching, 
he often flirted his tail in the manner of the Phebe; and, 
every few seconds, he emitted his note, — chebéc, chebéc, 
chebéc; varied sometimes into chebéc-trree-treo, chebéc-treee- 
cheu. 
The young were all hatched 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.
