April 20
  Cloudless & very warm. Wind light, N to N.E.
Ther. 41 degrees - 74 degrees.
  Spent the day at the farm driving up early
in the morning and back after dark. Near the house
I saw or heard Robins, Bluebirds, Chickadees, Tree Swallows,
a Purple Finch, Goldfinch, Field Sparrow,
several Juncos and Song Sparrows, Red wings, a female Cow bird,
the pair of Phoebes, Crows, Jays & Flickers.
Birds about the
farm house.
  At about 9 A.M. a male Broad-winged Hawk
appeared nearly over the barn where he soared in 
circles at no great elevation for several minutes giving
us a fair view of his characteristic tail markings.
To my eye the shape of this bird's wing is not strikingly
different from that of B. lineatus.

Hawk.
  As we were eating dinner the loud screaming of
a Red-shouldered hawk came to our ears through
the open door & rushing out we beheld three of
these fine birds soaring in company over the open
field in front of the house. One of them carried 
something that looked like a frog in his talons.

  In the forenoon Purdie & I visited Pulpit Rock
to see how the plants I introduced there last year
were getting on. We found the Berkshire hepaticas
in bloom; strange to say all but one plant had
white flowers. The yew and arbor vitae was all dead
but most of the other plants seemed to be doing well.
Plants at Pulpit Rock
  In the dense white pines near the rock we saw a 
Hermit Thrush and a Ruby-crowned Kinglet & heard
two Canada Nuthatches. A Partridge was drumming
not on the wall but somewhere S.E. of the rock.
