Little grebes are now in their winter colours, says Sheffield wildlife expert

The little grebe, or ‘dabchick’ as it is commonly known, is the smallest British grebe at about half the size of a moorhen.

These are diving waterbirds which are accomplished underwater swimmers feeding on both small fish and aquatic invertebrates such as crustaceans and insect larvae.

During the summer months the grebes are highly territorial and a pair will establish and defend their territory along a linear watercourse such as a river or canal.

Here they build their nests on floating platforms constructed from pondweeds and the like.

At this time, the adult birds are brightly coloured and highly vocal with a surprisingly loud whinnying song; you often hear them well before you see them.

By the time winter is upon us the little grebe loses its red and gold plumage and adopts a mix of subdued buff, off-white, and black.

The dark bill is changed to a pale grey, but they retain the bright yellow blob at the base.

If this winter is another mild one, then breeding numbers next year will to rise again.
