During the afternoon Mr. Kane visited the place with sixteen
boy scouts. Brownie was busy on the nest, so did not come, but two
of the young birds came out of the bushes in the glade and I fed them
with the spatula in the presence of the boys .(The Wren-Tit on her
nest was subjected to the scrutiny of 18 pairs of eyes in succession
at a distance of about 2 feet without being disturbed).
June 21st. At about 7:45 A.M. I went to the glade. Neither parent
was there but all three young birds appeared almost at once and
came to me to be fed. They are beginning to show their individualities
About 9, Dr. Reynolds with Mr. and Mrs. Harris called to see the
thrashers. As they came up the road, Brownie came out of the bushes
and jumped up into my hand for worms, much to their delight. After
a half hour or so, we went to the glade and Brownie came out of the
bushes with her whole family and gave a good exhibition of feeding
the young, getting worms from me, etc.

About noon I went into the glade--both parents absent--and
the three youngsters came to me(-They do not respond to call). One
of them is acquiring a parental attitude towards the others. It
takes worms from my hand freely, now and then carrying one to one of
the others, making the same chuckling sound that the parents made
when feeding the young in the nest. It also steps partly in behind
often the bird to be fed, just as the parents do and taps the prospective
recipient on the head or back to make it "open up". It then holds
the worm close to the other's bill,instead of thrusting it down its
throat, waiting for the thother to reach forward and take it; which
it usually does. This is exactly as Brownie and Greenie feed each
other and is different from the behavior noted yesterday. This morning
on one occasion, the giver of the worm "asked" for it back again by
opening its bill and crouching and,in its turn,reached forward and
