1905.
May 12 
  Forenoon cloudy and calm with fine misty rain. Afternoon    
clear with light N.E. wind.
  Arrivals: - Golden-winged Warbler 1 in full song, in orchard at farm;
Lincoln's Finch, 1 in millet patch at farm, 1 in road just north
of Benson's house; Black-billed Cuckoo, 1 in full song at Ball's Hill, 1 at
farm; Yellow-billed Cuckoo, 1 (silent) at farm.
  Saw two male Rose-breasted Grosbeak escorting a female
from tree to tree in an apple orchard. All three birds were
silent. The males showed no rivalry or jealousy of one
another. Walter Deane tells me that he saw a similar trio
in the garden in Cambridge the other day but his
male birds were displaying their plumage most vigorously 
as they fluttered about the female & they also had a 
singing contest.
  A Grosbeak in the woods near Pulpit Rock this morning
was giving the autumn note at short intervals and
another bird was announcing in the same way. I noted
this call on the spot then: "He'w-e, he'w-e a rather
sad note resembling somewhat the autumn call of the
Bluebird."
 The Bittern when on wing at a distance may be
distinguished from the Night Heron by its quicker wing beats,
its longer slenderer slope, & by the more turnaround and
of the back.
