Kingfisher – 2021 winter

Alcedo atthis – Glas y dorlan – breeding resident

Kingfishers often drift towards the coast in winter, often spending the season on the estuaries before moving back upstream to breeding areas. This movement was more marked when winters were colder and ponds more likely to be frozen over, forcing birds to move in search of food.


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.

Best places to see kingfishers in winter:

  • Bosherston Lily Ponds
  • Nevern Estuary
  • Teifi Marshes Reserve
  • Pembroke Millponds

Wetland Bird Survey

The slightly higher numbers seen on WeBS sites in 1995-96, 2009-10 and 2010-2011 probably reflect the colder winters in those years.

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.

These graphs will be updated as more data comes in.

Pattern of occurrence

Cumulative number of records per week in Pembrokeshire since 2000, taken from BirdTrack. Birds are more widespread during the autumn dispersal period, and also in winter when there are fewer leaves on the trees.
