cheeping sound suggestive of unappeased hunger. The old birds
usually alighted first on a box and then flew up to the nest
poising in front of it on rapidly beating wings for two or three
seconds. Once I saw one of them fly off with a white
excrement sack. At one time when two of my men were
working almost directly under the west an old bird went to
it & fed the young. The old [male] (I assume it is the [male])
roosts regularly in the wood shed attached to our house,
flying into it as twilight is falling.

Nuthatches feeding young in nest.

  The Nuthatches are still feeding their young in the nest in the
elm in front of the barn. I watched them for nearly half an
hour this morning. They usually came to the nest once every two
or three minutes. When one came just after the others had fed
the young & was apparently about to leave the branch it often
transferred its morsal [morsel] of food to the bill of it [its] mate who at once
turned about & entered the hole with it for the young. Whenever I
watched this closely it was the [female] who brought & the [male] who received
& took in, the food. This was always a small rounded object like a beetle
or its larva.
