 found Barely as a breeder, even in the Canadian zone. It ii 

 especially abundant in southeastern Pennsylvania, about 

 Philadelphia and in the lower valley of the Gusquehanna. 

 Mr. Dickey records it as very common in Green County. 

 Farther north I have found it to be an uncommon nester in 

 Clarion, Huntingdon, and Center Counties, tho I have found 

 the nest in all three counties. Prom Warren, in the heart 

 of the Canadian life zone, Mr. Simpson writes "Found a nest 

 and three eggs, June 14, 1912. My only breeding record and 

 the long time I ever even met this bird here." 



466a. Empidonax trailli Alnorum Brews t . Alder Flycatcher. 



The credit for adding the Alder Flycatcher to the 

 list of birds breeding in Pennsylvania must be given to 

 John D. Carter, who first observed them in the summer of 

 1906 about Pocono Lake, Monroe County. The following year, 

 the author saw several birds of this species at Pocono Lake 

 from June ninth to June Sixteenth, and, tho no nests were 

 found, the actions of the birds plainly showed that they 

 were preparing to nest. There appeared to be several pairs 

 scattered at intervals in the low, scrubby thickets along 

 the edge of the lake. Mr. Weygandt, in Cassinia, records 

 some birds seen near Cresco in July which were probably this 

 species, and search should be made for it in similar locali. 

 ties among the northern tier of counties.
