Often the song appears to keep time with the digging and is sometimes
accented when about to turn over a stone larger than usual. At other
times it is so continuous that one would not know that the bird was
digging. Often the pulsation of the throat is all that reveals the
identity of the singer. Both birds sing in this way.
As the birds became more friendly, I thought I would try to get
into closer touch with them, so I got a supply of meal-worms from Mr.
Brock and tried tossing them to the thrashers one at a time. Shortly
the tamer one would come to get them within 15 or 20 feet of me. I
then gradually dropped them nearer to myself until this one would take
a worm within an inch or two from the tips of my fingers where my out-
stretched hand lay on the ground, then run off. Gradually it would
not retreat so far or so fast. Then I tried spreading my fingers,
placing a worm between them on the ground and another worm in the palm
of my hand. Finally she, for I think it was the female, would take
the worm from between my fingers, but not the one on my palm. All
this time the bird would keep an anxious lookout for hawks, as I was
10 or 15 feet from the bushes in the open. Little further progress
toward getting the birds to eat from the hand was made for days, although
by December, 1932, they would come out of the bushes wherever they
might be, when called, almost any time and run to me for worms. Some-
times they would come from a distance as great as 75 yards in response
to call, my first intimation of their location often being on hearing
them answer me from their place of concealment. I arranged to carry
with me a small round tin box of meal worms, so that I would always
be prepared to feed the thrashers whenever they came and not disappoint
them. It soon became evident that the nearer I was to a brushy place,
more readily the birds would come for worms and the longer they would
stay with me, on account of their lessened fear of being caught by
hawks. They do not like to fly, such preferring to run. They are
