The New York State College of Forestry 
men was seen flocking with the other species at Kanahwauke Lake. 
The Tree Swallow can be easily distinguished from the other 
swallows of this region by its greenish blue upper parts, with pure 
white under parts, its name bicolor being peculiarly appropriate 
for it. 
26. Barn Swallow. Hirundo erythrogastra Bodd. 
The Barn Swallow is especially noticeable at Kanahwauke Lake, 
where it coursed over the water in tireless evolutions. As the 
season advances and the young are a-wing, these swallows perch 
on the wires near the water or in the neighborhood of their 
colony home, forming larger companies as they are joined by 
others in the progress of the season. The large barn near the 
Park entrance at Kanahwauke supported the colony in this 
locality, while other barns in various localities generally attracted 
groups of this swallow. 
27. Cliff Swallow. Petrochelidon lunifrons lunifrons (Say) 
The Cliff Swallow was not observed by me until August 1, when 
the growing flocks of swallows brought this species into associa- 
tion with the others at Kanahwauke Lake. I did not observe any 
colony of the Cliff Swallow during my stay in the Park. This 
swallow can be known by its dark blue head and back, creamy 
white forehead, chestnut throat, whitish under parts, and reddish 
brown rump. 
28. Scarlet Tanager. Piranga erythromelas Vieill. 
The Scarlet Tanager occurs in the Guest House locality in about 
the same proportion as at Bear Mountain. My notes regarding it 
at the Guest House did not add anything of interest to those men- 
tioned in the previous chapter. 
29. Indigo Bunting. Passerina cyanea (Linn.) 
The Indigo Bunting is very common in the Guest House neigh- 
borhood, associated with the shrubbery of the woods margins and 
open patches of bushes. On June 20 I found a nest of the Indigo 
Bunting, disclosed by the anxious chirping of the parent birds
