These are enormous flocks of starlings that have gathered to roost in a reed bed or on the struts of a long seaside pier.

But in the evening they gather again in large roosts in a reed bed, or in a group of small trees in a town square.

It made a giant curve across the reed bed before vanishing, calling loudly as it did so.

It was standing at the front of a reed bed, just inside the reeds, on the far side of a partly frozen lake.

We watched as a heron alighted close to a group of redshank and lapwings tending downy young at the edge of a reed bed.
