Identification

The Black-throated Diver is smaller than a Northern Diver but bulkier and bigger than the Red-throated with a stouter more horizontal bill, and bolder, more black and white markings. Its immaculate summer plumage is unmistakable and key features in winter plumage include a broad triangular white patch around the flanks and more extensive dark areas on the head, nape and neck, contrasting boldly with the paler cheeks and throat.

Habitat

Breeds on freshwater lochs and pools. Winters off coasts and occasionally on inland freshwaters.

Behaviour

Forms tight feeding flocks in winter

Migration

Birds leave their breeding grounds during September to October to coastal or more southerly areas, returning in April-May.
