"Some black and white, with a topknot, and some striped brown ones.

Aren't the brown ones Bitterns?
They look like one I saw in the miller's woods, and he called it a Bittern." "The striped ones are the young birds, now wearing their first plumage.
Bitterns prefer to live in freshwater meadows, or near ponds.

They are solitary birds, keeping house in single pairs, and after nesting-time wander about entirely alone." "Isn't it very hard to tell young Night Herons from Bitterns ?" asked Nat.
"It would be easy for you to mistake them, but the habits of the two species are quite different.

The Bittern nests on the ground, in a reedy bog, not in the woods, and may be seen flying in broad daylight, with his long legs trailing behind him.

But in spite of this, he is a difficult bird to find; for if anything is 'remote, unfriendly, solitary, slow,' it is the American Bittern, who often stands motionless among the reeds for hours." "That is just what the Bittern did that the miller and I saw," said Rap.
"We were hunting for a calf--the miller's things are always straying away, because he never mends his fences--and this Bittern was among some very tall grasses and dry flags; for it was along in the fall, when things were turning brown.
