I^D DwiGHT, Summer Birda of the Pe7i7isylvania Alleghtnites. [April 



Chordeiles virginianus. Nighthawk. — Not met with on North Moun- 

 tain, probably because there are no clearings except about the hotel. 

 Several seen at Cresson and vicinity. 



Chaetura pelagica. Chimney Swift. — Rather common everywhere. 



Trochilus colubris. Hummingbird. — Now and then one would be seen, 

 but they wei-e rare. 



Tyrannus tyrannus. Kingbird. — Not seen on North Mountain, doubt- 

 less on account of the continuous forest, and not common at Cresson. 

 It was more abiinchmt in the valle}' region. 



Myiarchus crinitus Crested Flycatcher. — One was seen on Wop- 

 sononock Mountain at perhaps 1800 feet elevation, and a few others were 

 noted near North Mountain, in the valley. 



Sayornis phcebe. Phcebe-bird. — A few met with wherever there were 

 houses, even near a deserted mill on North Mountain. 



Contopus virens. Wood Pewee. — It was rare at Cresson, and very 

 few were detected on North Mountain. 



Empidonax flaviventris. Yellow-bellied Flycatcher. — This species 

 was found on North Mountain only, a few along the cold brooks. Dr. 

 Warren states that many breed in Lycoming County and other mountain- 

 ous parts of Pennsylvania. Baird did not meet with it in summer. 



Empidonax minimus. Least Flycatcher. — Only detected in the 

 valle}', though there seems to be no good reason why it should not be 

 found on the mountains. 



Dr. Warren says: "1 have been informed that Traill's Flycatcher has 

 been seen in the mountainous parts of the State during the sutnmer." 

 The possibility of error in identifying the small Flycatchers is so great 

 that the actual capture of the bird should be the on\y authority for stating 

 its occurrence. 



Cyanocitta cristata. Blue Jay. — Ratlier common; noisy parties of 

 young birds met with frequently. 



[Corvus corax sinuatus.? Raven. — It was well known to the people on 

 North Mountain, but it is now very rare. Dr. Warren records it as resi- 

 dent in many counties.] 



Corvus americanus. Crow.- — There were no Crows on North Moun- 

 tain and very few about Cresson. 



Molothrus ater. Cowbird. — At Cresson a single bird was noted. 



Agelaius phoeniceus. Red-winged Blackbird. — A few were seen in 

 a wet meailow at Cresson. More common in the valley. 



Sturnella magna. Meadow Lark. — Several seen each day, near Cres- 

 son only. 



Quiscalus quiscula. Purple Crackle.? — Seen at Cresson only, where 

 a few bred. In the valley near Altoona (1197 feet) they were abundant. 

 A specimen obtained proved to be a young bird, probably quiscula^ and 

 one male that I saw at a distance of thirty feet was evidently of this spe- 

 cies. Still the crest of the Alleghanies must be somewhere near the 

 dividing line between qtn'scula and ceneus, and more material is desirable 

 to determine which is the prevailing form.
