Song of Blue Jay

Colaptes. It may be kept up ceaselessly for minutes
at a time and with occasional brief intermissions
for an hour or more. I have had it almost constantly
in my ears while writing the foregoing account of it.
March 30.  Now, at 12.30 P.M. the Jay is singing again
almost ceaselessly just outside my study window.
Among the familiar notes he keeps interpolating the 
usual loud bell call and with equal frequency an
excellent imitation of the Flicker's pe-eeck or ki-ou.
This I have not known happen before.
  Earlier in the day I saw one Jay of this
mated pair pluck a golden nightshade berry and
take it to the other (only a few feet away) who at
once accepted and swallowed it, at the same time
quivering its half-expanded wings and tail just as
young birds are accustomed to do when fed.
