Black-necked Grebe

Podiceps nigricollis (CL Brehm, 1831) BN BLNGR 120
Family: Podicipediformes > Podicipedidae

Black-necked Grebe, Liz Cutting

Black-necked Grebe is a rare breeding species in Britain, its small population largely restricted to central and eastern England. During the winter months the species may be found more widely on both inland and coastal sites.

Breeding Black-necked Grebes appear to favour shallow eutrophic lakes and pools with an abundance of submerged and floating vegetation. Favoured sites are typically quiet and undisturbed, and the species can be secretive when breeding.

The numbers of wintering Black-necked Grebes suggests that our breeding population is joined by individuals from elsewhere during the winter months.

Small grebes in summer are gloriously-coloured birds, but two of the three species are unfamiliar to most. Poor light or frequently encountered partially moulted birds can also cause some identification headaches. Let us help you separate these beautiful birds.

POPULATION SIZE

POPULATION CHANGE

The first UK breeding record of Black-necked Grebe was in 1904, and breeding numbers remaining very low for most of the twentieth century (Martin & Smith 2007). The population trend has been stable over the 25 years to 2019 (Eaton et al. 2021), having risen between the 1970s and the early 1990s (Martin & Smith 2007). The species has a scattered and localised breeding population in the UK and is monitored by the RBBP with a five-year mean of 53 breeding pairs over the period 2015–2019, almost all in England (Eaton et al. 2021).

DISTRIBUTION

Black-necked Grebes prefers sheltered coastal waters and large open reservoirs in winter. In winter they most abundant around the Thames Estuary and along the south coast of England. They are very scarce breeders in the UK, with most pairs in central and eastern England.

DISTRIBUTION CHANGE

Black-necked Grebes have become more widespread in winter and the breeding season, although there have been losses in Scotland.

CAUSES AND SOLUTIONS

Causes of change

The increases in the UK in the 1970s and 1980s are believed to be related to a general increase across north-west Europe (Martin & Smith 2007). However, the reasons for the increases are unclear.
