and a whistled peer almost indistinguishable from that
of the Pine Grosbeak. There were also various twittering,
screeping and even warbling utterances, emitted so very faintly
that one had to listen intently to catch them at all, even
when coming from very near at hand. Sometimes most
if not all the members of the flock would employ their
voices, for half a minute or more at a time, in giving
utterance to one or another of the sounds above described,
thereby producing a confused medley apparently no less
significant of social bird gossip than that to be heard so
often from Redpolls, Goldfinches, Sandpipers and various other
gregarious birds wherever they assemble numerously.
  Only when obviously apprehensive or startled - as by
the appearance of the Hawk - did the Grosbeaks [Evening Grosbeak] utter
any calls that could be heard far away. On such
occasions they made use chiefly of the whistled peer.
