This bird is occasionally found as a spring and autumn 

 visitor in New England, arriving about the 15th or 20th of 

 May. In its habits, it resembles the Least Flycatcher (.Z?. 

 minimus) , as it does also in its plumage: in fact, these two 

 birds and the Green-crested Flycatcher have been so much 

 mistaken for each other by different naturalists, the confu- 

 sion in whose descriptions is so great, that it requires a very 

 careful examination to identify either of these birds per- 

 fectly and accurately. I have had no opportunities for 

 observing the habits of the bird now before us, and can add 

 nothing to its history. Thompson, in his " Vermont Birds,"
