They were squirming about in the nest, gasping and hanging their
heads out over the rim. A shade was arranged for them, and this
did not deter the parents from continuing to feed them.
Okii, today, extended his exploration to my head, face and
neck, hammering my skull with blows that were somewhat too strong
for comfort.
Chisai, unsettled at 8 P.M., instead of climbing the wire to
get upon my hand, flew directly to my head and settled there. Both
birds, for the first time, while still showing preference for the
corner by the entrance door, would fly up to my hand when held
against the wire at almost any point.
July 3rd.
At 7 A.M. I was in the cage with the young thrashers. An
adult thrasher began singing overhead in the pine tree. I thought
I could tell that it was not Poni.
Soon, in the direction of another pine tree 30 feet to the south
I could hear a baby thrasher kipping. After a few minutes the
adult bird went to it and fed it, and I saw them both. The adult
was none other than "Broken-wing": one of the thrashers from Mr.
Sampson's place and one of the parents of Okii and Chisai! The
youngster was just out of the nest apparently and its head still
bore a plume of natal down. So Mr. Sampson's thrashers did rear
a second brood, although they seem to have left his place immediately
after I took their first brood.
(Q. Is Poni the other parent of this young bird as well as of
O and C? Compare renewal of song to the west with time of
capture of O and C).
B-W and the young thrasher stayed until about 9 A.M., when
judging from sound, they went down into the lower territory to the
north.
Okii and Chisai, for a week or more, have been suspected of
moultting. There are bluish gray places showing in their body plumage,
and they are looking shabbier.
Both are now interested in meal-worms for some reason or other,
especially if I hold the worm box in my lap. Okii now pounds the
back of my hand (digging) to get at the box concealed within it.
He does not "pull his punches" and, this morning, drew blood.
The bills of young thrashers at the age of O and C are much sharper
than those of their parents, as has been commented upon before.
The parents' bills are worn more from digging. Evolution should
have provided them with automatic means of keeping their bills
sharp, similar to that given to rodents.
About 10:45 Rhody showed up and sat in his new nest. When he
came down he followed me for a mouse, which was carried with full
ritual to nest 8-37 instead of to the new one. There he remained
for more than an hour resting. About 12:30 he came for another one
and treated this with ritual also. (Both were very small). I did
not see where he went, but it was not to 9-37.
