owner kept guard over his barnyard with a gun, shooting at Crows 
and woodchucks, but he seemed not to know of the existence of 
this hawk family on his premises, as his poultry was never threat- 
ened by the adult harriers. This hawk has reddish brown showing 
on the bend of the wing and under parts, the latter somewhat 
streaky. It can always be known by its loud. Blue Jay-like calls, 
resembling the syllables “ kee-yuhT uttered most frequently in the 
neighborhood of its nest. Its occurrence seems to be restricted to 
special localities in the Park, preferably limited swamp margins. 
14. Cooper's Hawk. Accipiter cooperi (Bonap.) 
A Coopers Hawk was seen frequently at Cedar Pond. On July 
12 it was startled from a low perch near the pond shore, and begin- 
ning just above the tree-tops, it began to ascend, making four or

tions led me to conclude that the Cooper’s Hawk is uncommon and 
of local occurrence.

On July 11, 1919, I saw a Mourning Dove in the Bear Mountain 
region, on the old Queensboro road, near the Forest of Dean mine. 
It was sunning itself in the road, and flew up ahead at our 
approach. While common in all the surrounding agricultural dis- 
tricts, the Mourning Dove does not appear to be a regular inhabi- 
tant of the Park proper. 
17. Black-crowned Night Heron. Nydicorax nydicorax 
ncevius (Bodd.) 
On July 22, 1919, two of these herons appeared at Cedar Pond, 
in company Avith a single Great Blue Heron, fishing along the
