Little Grebe – 2021 Winter

Tachybaptus ruficollis – GWYACH FACH – Breeding resident and winter visitor

Little Grebes spend the winters at a variety of sites from small pools, such as irrigation reservoirs, to large sheltered estuarine embayments. The coastal sites are more important in cold winters when inland sites freeze over. The susceptibility of the species to cold winters is illustrated by the drop in numbers (on WeBS sites at least) after the 2009-2010 and 2010-11 winters.

Distribution

This map was produced by the West Wales Biodiversity Information Centre using data collected between November and February for the BTO Atlas 2007-11, with additional data collected in 2011-12 winter to fill gaps in coverage.

Main sites:

Pembroke Millponds – the fourth most-important site in Wales for little grebe

The Cleddau Estuary complex as a whole is the fifth most-important site in Wales, with the greatest concentration now being on the Pickleridge lagoon at the Gann Estuary.


Wetland Bird Survey

Note that Little Grebe were counted only on freshwater sites before 1994-95

Data for June and July are collected by Jane Hodges during the annual surveillance of summer shelduck populations on the Cleddau Estuary complex. There are no counts in August. The September to March data is collected from sites across Pembrokeshire (including the Teifi Estuary) for the BTO Wetland Bird Survey.
