BIRDS OF EAST PENKSYLVANIA. 



Yellow-bellied Ily- 

 catcher. 



Wood Thrush. 



Least Flycatcher. . . Enqndonax miimnus. Rather rare, 

 arriving in April on its northern 

 migration, and returning early in 

 September. A few remain to breed. 

 (S. & A.) 



Green-crested TljcitcheT. Empidmajo acadicus. Small Pewee. 



Frequent from the beginning of May 

 to the middle of September. It is 

 generally found in the most secluded 

 parts of woods. (S.) 



Empidonax flaviventris. Eai-e. It 

 arrives in the middle of April 

 on its way north. Dr Slack 

 found it breeding near Trenton. 

 (S. & A.) 



Tardus viiistelimis. Song Theush. 

 One of our sweetest songsters, and 

 plentifully distributed. It arrives 

 about the middle of April, and 

 departs in October. (S.) 



Turdiis Pallasii. Not uncommon. It 

 arrives in April, and again late in 

 October, on its way south, when 

 it is more abundant along the sea- 

 coast. This bird is very like 

 Turdus Swainsonii, but the tail and 

 tail coverts are rufous. A few have 

 been observed during Winter when 

 that season has been open and mild. 

 (S. & A.) 



Turdus fuscescens. Tawnt Thbush. 

 Plentiful from the beginning of April 

 to October — a few remaining during 

 Winter. Many migrate further north 

 to breed. (S.) 



Tu7-dus Swainsonii. Hare. It arrives 

 in the end of April. A few also 

 of this species have been seen in 

 Winter. (S.&A) 



Hermit Thrush. 



Wilson's Thrush. 



Olive-backed Thrush.
