Habits. This well-marked species was first ohtained in Carlisle, Penn., 

 and described ]>y the liairds in 1843. It has since remained a comparatively 

 rare and scattered species, and has been only seldom met with. I found it 

 hreedin<j in the vicinity of Halifax, and also among the Grand Menan 

 Islands, and in both cases was so fortunate as to be aide to obtain its nest 

 and eggs. It has been found near Calais by Mr. Boardnian, and its nest 

 also procured. It has also been found breeding near Trenton, X. J., by 

 Dr. Slack, and in a not distant locality in the same State by Dr. Abbott. 



Dr. Coues observed the Yellow-bellied Flycatcher to be a rather rare 

 spring and autumnal visitant at Washington. As specimens were taken there 

 July 28, undoubtedly they occasionally breed there. They appear early in 

 lilay, and go south the latter part of September. 



Two specimens of Flycatcher, identified as of this species, are recorded 

 by Professor Ileinhardt as having been taken at Godthaab, Greenland, in 

 1853.
