the break up of the family circle , especially if Greenie persists
in his present policy of repelling its members when they ask him for
food. He took worms for himself when they were offered him and repul-
sed the babies and they showed no disposition to follow him toward me.
When I approached them, they retreated into the shrubbery slowly.
Brownie has been the tie that has kept the group intact, evidently.
When Brownie came off the nest there was a change. The oval lawn seems
become
to have, for the time being at least, became the center of activities.
I focused the movie camera with a 4" telephoto on the original
thrasher feeding table, 26 feet away. Brownie soon came to the table
for food for the young. (9A.M.--variable light account of floating
clouds--f/5.6--26 feet--footage from 47 to 59½)* I wanted to get her
running to and from me in line with the camera, so changed to a shorter
focus lens, without moving the camera. (Footage from 59½ to 78--1"
len s--light fairly good--f/6.7--Dis. from 26 feet down to 10 feet)
As the sun became stronger, I changed to f/8, and as a wren-tit
appeared at the table, although rather far away for so small a bird,
I took it with the 1" lens. (Footage to 80½) In the meantime Brownie
was amongst the columbines with a big black and yellow swallow-tail
butterfly,which she had seized on the grass, and which she gave to
one of the young. I was not quick enough to get her in the act of
catching it, as the camera was on the tripod. (To 95 feet, Brownie
feeding young on the lawn--Also I feed one of them)
On change of shift at the nest, Greenie came to the lawn and started
digging it. I now have, I hope, positive evidence to use against him
in the shape of the last 5 feet of film. (95' to end--1"--f/8--
camera held in hand--Greenie repudiates Lawn Agreement).
I then sat on the grass 3 feet from the feeding stand. Brownie
came and began feeding two of the young --the other being absent--
with kernels of corn and wheat picked out of the suet, the latter
