48 THE WREN. 
NOTES. 
It has been said that one way to tell a Bittern from an immature 
Night Heron is by the latter’s habit of alighting in trees whereas the 
Bittern never does so. In this connection it may be of interest to 
note a Bittern’s perching in a tree. On May 1, 1909, Brainerd, 
Peters and Creesy saw a Bittern fly across the Charles River below 
the Farm St. Bridge, Dover, and light in a white pine. Then he 
stiffened up in his characteristic manner, his streaked underparts 
showing conspicuously against the dark green of the tree. 
Among the birds noted by Messrs. Peters and Brainerd on a trip 
to northwestern Berkshire from May 29-31 inclusive were — May 
29 Philadelphia Vireo, 2 at the base of Mt. Greylock. At the sum- 
mit, a few Mourning Warblers, 2 Bicknell’s Thrushes singing. 
May 30. On Greylock an Olive-sided Flycatcher calling. At 
the base, an Alder Flycatcher. May 31. A Yellow-bellied Fly- 
catcher at Lanesboro; a pair of Rough-winged Swallows, Pittsfield. 
The Killdeer, seen on May 12 at the brickyard on Concord Ave. 
by R. Morse bred at the Pout Pond Swamp. The nest was dis- 
covered by Mr. George Nelson on June 27. Mr. Nelson secured 
photographs of both eggs and young. The birds were seen on June 
28 by Messrs. Peters, Brainerd, and Creesy. 
On the same day these same fellows saw a tree containing a 
nest of a Red- headed Woodpecker at Waverly. One of the old 
birds was seen in a grove near by. 
(Shore bird notes have been treated in the body articles.) 
On September 12 J. L. Peters saw a Duck Hawk attempt to 
carry off a tin Yellow-leg decoy, and being unsuccessful with the 
first one, swooped at another before he discovered his mistake. 
A Blue-winged Teal was seen at West Tisbury on September 15 
by J. L. Peters. The Whip-poor-will was heard for the last time 
on that date. 
Jaegars of both species were unusually numerous throughout 
the season. A Parasitic was seen early in July by J. Kittredge. 
One specimen each of the Parasitic and Pomarine was seen at Plum 
Island, October 7, by R. M. Marble and J. L. Peters. 
Barron Brainerd reports the following general notes. September.
