Passerculus sandwichensis savanna.
Lakeside, N.H.
1907,
July 24.
  A Savanna Sparrow perched in a bush by the roadside near
Lakeside Hotel evidently anxious about young which must have been
concealed in the grass field beyond the fence, called tsup, tsup, 
incessantly as long as I remained near at hand. This note was
very like that of a Junco.
July 25.
  What was evidently the same bird for it was perched on
the same twig, did not once give the tsup note to-day, but instead
called tit, tit, ti-ti or tit, tit-ti-ti ot tit-ti-ti-ti. This 
chirping bore some resemblance to that of a Chippy (S. socialis)
but was sharper and more wiry.
  Another bird in the Sargent clearing this evening used
the same tit or ti-ti calls. It was at first in a leafy tree and 
afterwards on a rock near by. It seemed even more anxious than
the bird at Lakeside.
