5. Rough-winged Swallow. Stelgidopteryx serripennis (Aud.) 
The Rqugh-winged Swallow was first pointed out to me at 
Kanahwauke Lake by Mr. E. J. Sawyer, where a pair were spend- 
ing the summer, associating with other swallows. Later it was 
observed at Bear Mountain, along the river-front, and at places in 
the Park interior. This swallow is no doubt more common in the 
Park than my records indicate, for I overlooked its presence in 
1918. The Rough-winged Swallow can be identified by its dark 
brown upper parts, with throat and breast uniform brownish gray, 
and belly whitish. It lacks the dark breast band which character- 
izes the Bank Swallow, and its twittering call is quite distinctive. 
6. Purple Martin. Progne subis subis (Linn.) 
The Purple Martin seems not to have any established residence 
in the Park domain, no colonies being seen in either 1918 or 1919. 
Individuals were seen only in association with swallows at Kanah- 
wauke Lake in the flocking season in late summer. It is likely 
that martin boxes placed at Bear Mountain Inn, Kanahwauke 
Lakes, Cedar Pond, and Summit Lake Camp might attract these 
desirable birds for summer residence. 
7. Slate-colored Junco. Junco hy emails hy emails (Linn.) 
The surprise of the season of 1919 was the finding of a Slate- 
colored Junco spending the summer near the Guest House, on the 
Kanahwauke Lakes. A male Junco was seen June 17, associating 
with a particular pair of nesting Field Sparrows, and thereafter it 
was noted regularly throughout the season until I left the Park on 
July 31. The Junco was alone, and persisted in attaching itself to 
the Field Sparrows in a manner that made it rather annoying for 
its associates. Particularly when they were carrying food for their 
young in the nest, and also when the young became active for 
themselves after leaving the nest, the adult sparrows were followed 
closely by the Junco. At times it separated itself from its chosen 
companions and sang its plaintive trills, or gleaned for itself in 
the Junco manner, but the chirping of the sparrows was generally 
the stimulus for it to fly again to their company. Why this J unco
