COUES, BIRDS OF NEW ENGLAND. 265 



Massachusetts. It is not, I believe, recorded from Maine. 

 But Mr. Samuels erroneously omits it from his Massachu- 

 setts list. Earlier authors speak of it as being very 

 common, but so far as I can learn it is now quite rare. 

 At Washington, D. C., it is by far the most abundant 

 species of the genus. 



Empidonax Traillii Baird. Traill's Flycatcher. Sum- 

 mer resident ; not abundant. Erroneously omitted from 

 Mr. Putnam's list, though given by previous and subse- 

 quent authors. 



Empidonax minimus Baird. Least Flycatcher. Sum- 

 mer visitant. Abundant, especially in Massachusetts, 

 where it "exceeds in abundance all the other Empidonaces 

 taken together " (AIL, p. 54). It has a very extensive 

 northern range ; quite into arctic America. 



The earlier authors appear to have always mistaken this 

 species for Acadicus, and this is the reason they used to 

 speak of the latter as being abundant. (See Brewer, 

 Am. Nat., I, p. 119.)

Empidonax flaviventris Baird. Yellow-bellied Fly- 

 catcher. Summer resident ; and rather more common, I 

 suspect, than most collectors are aware. Its range of 

 habitat, times of migration, and general habits, are much 

 those of minimus ; and it is difficult to discriminate be- 

 tween the two at gun-shot range. E '. flaviventris is rather 

 a more wood-loving species than minimus, and perhaps 

 breeds farther south, as I have taken it in July, at Wash- 

 ington, D. C., where I never saw minimus except during 

 its migrations. (Omitted from Sam. 0. 0.) 



TURDID.E. 



Tardus migratorius Linn. llobin. Chiefly summer 

 resident, breeding abundantly everywhere ; but a few 

 doubtless remain, except in very severe winters, in the 

 more southern portions.
