  " [Dendroica] blackburniae.- It would be strange if this
species is not at least fairly common here but
the only individual noted was an adult [male] seen
by Mr. Deane, July 19, in pasture spruces on
Ben Mere farm.
  " [Dendroica] maculosa. - Abundant, frequenting spruce grown pastures
(Ben Mere farm) and spruce and hemlock woods
(Cunningham Pond and base of Park Monadnock). At
the bog near our house I frequently heard them and
occasionally four males singing at once. The usual
forms of song here are witty-witty-witchy, witty-witty
witty-witchy or witty-witty-wríÂchy. Young in full
autumnal plumage from July 23rd. The old males
continued in full song up to July 30th and I heard
