After a long minute, a bird twittered, and then another one.

The birds twittered to one another as they prepared for their sleep.

Above them, on lower branches, other birds sat and twittered.

The birds are twittering to each other about the indifferent season.

Little transparent birds twittered in a circle around his head.

She's like a little bird, twittering away, and all the time you know that sharp mind of hers is thinking along on another level.

She forgot that the sun was shining and the birds were twittering.

The only signs of life were the birds twittering in the thatch around the windows.

The bird that had been singing all night, confused by the huge full moon, twittered into silence.

A few birds twittered cheerfully to themselves in the branches as they settled down for the night.
