Passerculus sandwichensis savanna.
Lake Umbagog.
1907,
July.
  Savanna Sparrows are very common and generally distribu-
ted throughout the hillside pastures and grass fields in Upton and
Cambridge. In places they breed in what are practically small
colonies. This is the case in the intervale on the Lake shore, in
front of Lakeside Hotel where, within the space of a few acres,
one may start as many as ten or a dozen birds or hear several
males singing at once. They sing very late into the evening and
very early in the morning as well as during cold rainy weather
when most other birds are silent. The songs of the birds found a-
bout the lake seem to me less strident and more musical and varied than of
those which occur on the sea coast. They are very insect-like,
however, and coming, as they often do, from beds of grass where
the birds are concealed, are strongly suggestive of the chriping
of crickets mingled with the   of grasshoppers.
