Accipiter fuscus
Middlesex Co. Mass. [Middlesex County, Massachusetts].
1875 Nest of Corvus Americanus
April 26 [April 26, 1875] to escape. I took the eggs & left the
bird in hopes of another litter. On 
the way home saw two Accipiter fuscus
flying Northward. H.R. Godwin
came out to see me in the afternoon. 
Saw our common little yellow field
butterfly out this morning, for the
first time.
  Apr. 27 [April 27, 1875] Clear but rather cool. Started off immediately
after breakfast in my buggy taking dinner
for the horse & myself. Drove up to
the lane (Shade St) where I once found a hawks
nest with young and tying my horse,
spent the whole forenoon hunting the
woods in that neighborhood for the
nests of raptorial birds. Found abundant
signs of owls especially Bubo Virgin. [Bubo virginianus]
but could not discover any of their
nests. Got a Crow's however with 4 eggs.
The birds were in the immediate
neighborhood and when I commenced
ascending the tree, both kept flying
overhead (out of gun range however)
cawing incessantly in an angry tone.
The nest was in a low second growth
pine, not over 20 ft. [feet] above the ground.
Started as many as 10 grouse and
hearing one "drum" a number of times
crept cautiously up when he started
off a stone wall. I heard a bird drum
on the same wall & indeed on the
very identical stone while out with R. Deane [Ruthven Deane]
some four years ago, and returning
