4 months of nest building activities, laying, incubating and feeding
to me
young it is somewhat surprising to see the plumage of the adults in
such good condition, although they spend a good deal of time on it
when their various necessary activities will permit.
I have not seen any of the birds, old or young, eat fruit of
any kind. They have had plenty of opportunity to get it on the trees
and bushes and I have offered it to them repeatedly. In the latter
instance, they have merely turned it over with their bills.
By this time, these observations were consolidated, they would
probably aggregate several thrasher-days, and in all that time I
have yet to any thrasher use a foot in digging or scratching the earth
or moving any object whatever, except that it does scratch itself, of
course, and in stretching out a wing toward the ground as birds do,
it will use a foot to push out the wing to its full extent--also as
other birds do.
Again today I noticed the fly crawl under the young bird's feathers
and disappear without action from the bird.
About 4:30 I took a visitor into the glade when I was not properly
equipped with food, and as luck would have it, all three youngsters
ran to my feet at once and one of them flew up and clung to my arm
as I stood there. I had to call to Julio to bring grub at once so as not to disappoint
them. During this period, Greenie appeared and the young birds took
refuge behind my chair and watched him for a time, then emerged to
find that he was not really savage. For the last two or three days,
the parents have eased up on their hectoring, but the youngsters
are not quite certain of their good faith. They do not tease for food
and are not offered any.
June 30th. About 8 A.M. I went to the glade; not a thrasher in sight
and no indications of their presence. After whistling and calling,
the young ones began to appear until all were present eating from the
