Greenie's
Song.
(372)
About 8:30 one was singing its undersong near the oval lawn. I waited
for it to come out. It climbed to the top of a flowering peach and called
scrap repeatedly, then dropped down in front of me with a loud quee’lick!
It was Greenie. After a meal-worm or two, he adjourned to the lawn and
got cut-worms; thence to the glade, where I followed. There he sat in
the bushes about 15 feet away and continued his vocal exercises, grad-
ually working over towards me. For about 15 minutes he lay on the ground
9 feet from me and back towards me in the open and continued his song,
occasionally turning his head to look back at me. He then moved to a
branch about a foot above the ground about 6 feet away facing to my left
continuing his song, but putting a little more pep in it so that he had
to pump with his tail and jiggle up and down on the branch. When he jumped
down and started to dig still nearer me and still singing, the hint was
too obvious to disregard and I rewarded him with a good meal of worms,
one at a time, for his fine entertainment. At first I held my hand near
the ground where he would have to stretch to the utmost to get the worm
unless he jumped upon my hand. As he did not intend to jump up until
he got ready he would hand his hooked bill over a finger and pull down
in an effort to get the worm, tickling my fingers with his throat feathers
and bristles at the base of his bill. Finally he decided to jump up.
I left at 9:45 and he had gone back to his song. This was a very good
show for the shy Greenie, possible only when Brownie was not around, as
otherwise he would hold back. I made pencil notes while he was singing
in an attempt to record some of his phrases, and here it might be well to
note that the thrasher comes the nearest to using articulate words of
any of the songsters with which I am acquainted. Some of the phrases can
be recorded almost exactly and are easily recognizable; when repeated,
it may be days afterwards. Of the undersong, it may be said, that but
a very small proportion consists of imitations and phrases which can be
even approximately expressed in writing, by far the larger part is made
up of the thrashers own contributions .
