Concord, Mass.
1912.
April 1 to 
July 1

  Cistothorus palustris et Stellaris. - None observed by me. Nor has Dexter
been able to find any except at Wayland and then he noted but
one bird, a [male] palustris singing near the bridge late in June.
  Anthus ludoviciana. - On May 5 [May 5, 1912] I saw four Titlarks flying
low over the river near Hunt's Pond. They uttered the usual
flight call (pip-it, pip-it).
  Helminthophila chrysoptera. - Golden wings have ceased to
breed anywhere at or near the Farm. Nor did I note 
any this year during migration. Two were seen between
Fairyland and Walden Pond by W. Faxon, late in May.
On that same day he saw six in the same locality.
  Helminthophila leucobronchialis - A fine typical [male] singing.
Neither this bird nor the Golden Wings could be found
afterwards although the place was repeatedly visited. 
  H. ruficapilla [Helminthophila ruficapilla].- After migration was over I noted species only
 twice - on June 3 [June 3, 1912] when I heard a [male] singing near Bigelow Road and
on June 29 [June 29, 1912] when one sang (once only) on our Berry Pasture at 7 A.M.
