BIRDS OF ESSEX COUNTY. 23 I 



During June, igor and 1902, Messrs. F. G. and M. C. Blake found the 

 bird in Andover, where it undoubtedly breeds. It was seen in Swampscott on 

 August 22d, 1883, and on May 23d, 1891, by Mr. W. A. Jeffries, and at 

 Ipswich on May 21st, 1904, by Mr. H. W. Wright. There are two specimens 

 in the Peabody Academy collection. 



189 [461] Contopus virens (Linn.). 

 Wood Pewee. 



Common summer resident ; May 2 1 to September 1 5 . 



Eggs : June 10 to July 10. 



In the farming country of Essex County with its numerous old orchards 

 this bird is common, and its delightful notes, although not its full song, may be 

 heard after the breeding season till its departure for the south. 



190 [463] Empidonax flaviventris Baird. 

 Yellow-bellied Flycatcher. 



Uncommon transient visitor ; May; August 25 to September. 



This Flycatcher is easily overlooked and it may not be as rare as it appears. 

 Mr. J. A. Farley tells me that he considers it not uncommon. 



[465] Empidonax virescens (N'ieill.). Acadian Flycatcher ; Small Green-crested 

 Flycatcher. Entered in Putnam's 1856 list as "summer visitant, abundant." This probably 

 referred to the Least Flycatcher, E. minimus. The Acadian Flycatcher is a more southern 

 species with only one record — Hyde Park — for the State.' 



191 [466a] Empidonax traillii alnorum Brewst. 

 Alder Flycatcher. 



Rare summer resident ; May 20 to August. 

 Eggs: June 16 to July 3.
