We have seen something like a horn sticking out of the tree, though it looks more like ivory than horn.

It may be the bill of a bird; but as to a bird itself, or the nest of one, where is that, pray ?" Ossaroo intimated that the nest was inside the tree; and that the bird was on the nest just behind its beak, where it ought to be.
"What! the bird is in that hole where we saw the white thing sticking out?
Why, it quite filled the hole, and if there's a bird there, and what we saw be its bill, I have only to say that its bill must be as big as its body--else how can it get out and in through so small an aperture?
Certainly I see no hole but the one.

Oh! perhaps the bird is a _toucan_.

I have heard there are some of that sort that can go through any place where they can pass their beaks.

Is it a toucan, Ossaroo ?" Ossaroo could not tell what a toucan was, never having heard of such a bird.
