different kind of talk than she has used before. She ate
soft food and when I held the box of worms out to her,
she threw out all of the bran with side sweeps of her bill
back and forth, rapping the side of the box at the end of
the stroke. After eating all the worms she picked up a
twig about three feet away, considered it for a time and the

looked up into the branches, but did not go up to it. I
removed this nest some time ago. They then showed interest
in the surrounding trees, walking under them and looking

location as they have done on both former occasions. If
they run true to form, they will not attempt to keep its
location secret.
The incubating period of the first egg was not less than 13
days and not more than 15 days. Not having marked
any of the eggs, no closer approximation can be made.
Incidentally, it looks as if the birds themselves did not

could hear him digging in the leaves not far away. These
notes will show that, by feeding the birds, they are
