  Song Sparrows, Field Sparrows and Towhees. There were
also a few Robins, Catbirds and Brown Thrashers and
at least two male White-throated Sparrows. All of these
were settled in or near the bog; and in neighboring woods,
thickets or fields within easy hearing were Black-throated
Green Warblers, Red-eyed Vireos, Grass Finches, Indigo Birds and
Goldfinches. Among the occasional or chance visitors were Winter
Wrens, Golden-crested Kinglets and Solitary Vireos. Still more 
rarely a Marsh Hawk would appear through an opening
among the trees and after beating the bog systematically
pass out at the opposite side. On one occasion a Quail
whistled for an hour or more at short, regular intervals
in a field not far off. The wide-roaming Swallows, Swifts
and Nighthawks were, of course, often seen passing and
repassing close over the trees. 
  This intermingling of northern and southern birds, not
often seen in such close association, at least during
the breeding season, never failed to interest me and
then there was the rich musical treat afforded every fine
evening when the Hermit Thrushes, Peabody birds and
Field Sparrows were singing freely. There were always two,
often three, and occasionally four Hermits singing
within hearing of one another and the best bird had
an almost faultless voice. One of the Field Sparrows, also,
was an exceptionally fine singer.
