Middleeex County, Mass, 
Apr. 12. 
Started five in the Pine Swamp. Their devotion 
to this favorite haunt is remarkable. 
May 27. 
A pair in the Fresh Pond swamps. 
June 1. About twenty—five in the maple woods bordering the 
brook beyond “Bloek Island*; shot one which was in warn 
immature plumage. Searched every thicket and piece of 
v/oods throughout these marshes without finding a single 
nest. about half of the birds seen were immature, evi¬ 
dently they were not breeding here. 
Aug. 31. Shot an adult in the Maple Swamp; it was moulting, 
most of the wing-feathers being fresh ones. It had only 
one plume and the steel-blue of the back and crown was 
replaced by the dark ptumbeous. lustreless plumbeous. 
Shot one in brown plumage. It was sitting on the 
ground on the sunny side of an alder thicket bordering 
Alewife Brook, One of its wings had been broken and hsd 
healed in such a wayr, jr that it could not be used in 
flight. The bird was in good condition and had evi¬ 
dently established itself by the open brook kept free 
from ice by th^ v/arm sewerage matter now discharged into 
it. The thermometer has fallen to zero during the 
past two nights and the marshes are froeen solid.

In the “Boston Daily Advertiser* for February 12 
James Russel Lowell writes; “I have seen them every even¬ 
ing up to the 12th of February. The largest number I 
have counted is eight, though there are not doubt more". 
They are also reported by J.N.Clark as wintering at Say- 
brook, Connecticut in numbers, and a flock was seen at 
West Newton, December 31, 1875 by Mr.Warren. 
Visited Prof.Lowell’s place this evening to see the 
Night Herons. Three flew from the pines shortly after 
sunset, each uttering its loud quak as it left its roost 
and all heading towards the Charles River marshes. The* 
evening was cold v/ith blustering north-west v/ind. 
! 
Started one from an apple tree behind Mt.Auburn. 
The tree was so loaded with damp snow that it afforded 
nearly as dense a shelter as when covered with summer 
foliage. 
I hoar them frequently at dusk now, calling to one 
another as they circle over the Charles River marshes. 
On several occasions lately I have seen them leave Prof. 
Lowell’s pines at dusk; a few also roost still in what 
IS left of the old Pine Swamp.

One seen in the cedars, Watertown, by Frazar.
