(Spinus tristis) with its accompanying perchicoru * call? 
It appears to be peculiar to the [male] and to be performed
only in the breeding season; yet the true song and the
bird's manner of flight while singing, are wholly different.

  Pooecetes gramineus.  - Throughout this region the Vesper Sparrows 
appear to have the upland mowing fields
wholly to themselves and everywhere they are
abundant. The record of singing is as follows:
July 5-12 (2 or 3 daily) 17*(1) 18* (1)  19* (2) 20* (3) 21* (2) 24* (2)
25* (1)  August 8*(1) (full song over at sunrise). The birds noted on
the 24th were found by Mr. Dean near the 
summit of Pack Monadnock.
  Junco hyemalis. - My record for the region lying about
Ben Mere farm July 7* (1) (Cunningham Pond) 20\ 1 juv. ,
first plumage (in field near our house), 21* (1) (Cunningham 
Pond) 23 * 1) (valley below house) ) indicates that
the Junco is not common at the middle or
lower levels but on July 24th W. Deane found it in
great abundance along the bare crest of
Pack Monadnock, hearing there, he feels sure,
the songs of at least a dozen different birds.
  Spizella socialis. - Common about farming land and houses. 
Vigorous and general singing ceased about
July 20th but there was occasional [delete][?][/delete]
or listless singing for two weeks or more after this. 
July 18* (1) 19* (1) 20* 91) 30* (1) August 1* (circled) (1) (at sunrise),
August 3* (1) sunrise  5* (1) (do.) **(1) (do.) 9* (1) (do.) 10* (1) (do.)
