Pair of Buteo lineatus

  The Red-shouldered Hawks at Holden's Hill were
hanging about the old nest in the big chestnut. The [male] was
perched for several minutes in a dead pine on the
hillside above the chestnut. The [female] alighted within
a few yards of him for a few moments but kept
for the most part in the air soaring in wider
circles, rather high, screaming almost incessantly.
He answered her every now and then from his
perch, opening his mouth very widely at each note
and I could not detect any difference between
his cries and hers. The two made the whole
country ring with their wild, thrilling music for
to my ears the voice of this Hawk is one of 
the most musical sounds of our N.E. woods.
Both birds were in fully adult plumage with
red breasts & pure white tail bands. They
did not seem to be much disturbed by my presence.
