parts. The female lacks the brilliant throat marks, but as a hum- 
mingbird she is easily identified. On May 25 I watched a female 
hummingbird shaping the foundation of her nest. She had chosen 
a site on a dead twig drooping below a spray of green leaves, in 
the lowest branches of a young oak tree on a rocky wooded slope 
near Iona Island station. In several of her visits to the nest she 
did not appear to carry material, but would perch on the edge of 
the little downy mass or in it to press it into shape. No male was 
seen while I watched her movements. 
46. Chimney Swift. Chaitura pelagica (Linn.) 
The Chimney Swift is the leading aerial navigator of the region, 
flying here and there over the open areas and above the woods 
in its tireless quest for winged insects. It is not really a swallow, 
and can easily lie distinguished from the swallows by its stubby, 
cigar-shaped tail, and the submarine form of its body, and its uni- 
form very dark brown plumage. In flight it utters a loud chat- 
tering, chipping series of short notes, easy to recognize. 
47. Whip-poor-will. Anirostomus vociferus vociferus (Wils.) 
It was ten o’clock on a' clear moonlight evening, May 24, when 
I first walked up the gradient leading to Bear Mountain Inn from 
Iona Island. I paused to read the words, “ Entrance to Bear 
Mountain Inn ”, and at that moment there came across the little 
lawn-plain a familiar call, “ whip-poor-will ”, oft-repeated, as a 
kindly welcome and an earnest of good ornithological things to 
come, wafted as an added element of charm to my first evening 
walk at Bear Mountain. This evening voice, heard on various 
occasions during my stay at the Inn, comprised all my knowledge 
of the Whip-poor-will in that locality, but elsewhere in the Park 
it was my fortune to experience a closer intimacy with this inter- 
esting bird, as noted under the comments in Chapter IV of this 
report. 
48. Flicker; Northern Flicker. Colaptes auratus luteus 
Bangs 
The Flicker is the common woodpecker of the region. Its size 
makes it a prominent feature in the bird life of the locality,
