Knot – 2020

Calidris canutus – PIBYDD YR ABER – Winter visitor and passage migrant. 

The knot breeds on the high Arctic tundra of Canada, Greenland and Russia.  The majority of those wintering in the UK are of the Greenland and eastern Canada subspecies.

Most of the UK wintering population is on the east side of Britain, although flocks of several thousand do occur on the Dee, Dyfi and Carmarthen Bay estuaries.  However, numbers in Pembrokeshire seem always to have been relatively small.  We just don’t have the vast open mudflats that this species prefers.

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.

The most likely places to see Knot in Pembrokeshire are the outer parts of the Cleddau (although they are occasionally seen further upstream), Teifi and Nevern Estuaries, and also on the large beaches of Freshwater West and Frainslake.

Movements

The only colour-ringed knot recorded in Pembrokeshire was T7 (above) on 10 March 2019.  It was ringed as an adult on Merseyside in 2017, and spent that winter there.  This particular colour-ringing project has shown that there is interchange between Merseyside, Deeside and Ireland.  It is possible that T7 had spent at least part of the 2018-19 winter in Ireland and was now on its way east to join thousands of other knot on the Waddensee where they fatten up for the flight to their breeding grounds via staging posts in North Norway and Iceland.   It was last recorded back on Merseyside in July 2019.

As we see only small numbers of knot in Pembrokeshire, it is worth looking carefully for birds with colour-rings or flags.  Ideally get the number on the flag, but even a record of the colour and which leg it is on can provide useful information.

Thanks to Jim Wilson for the colour-ring information.

Shoveler – winter

Anas clypeata – HWYADEN LYDANBIG – Winter visitor and sparse breeder

The shoveler has a breeding range that extends through Eurasia and Western north America. In general, it migrates well to the south for the winter with a few areas, such as Britain, the Netherlands and the west coast of America seeing birds all year round.

Occasionally one or two pairs breed in Pembrokeshire, but really they are a winter species here. Generally they are found on freshwater sites and in sheltered estuaries.

Numbers are variable, but probably around 100 in most winters – double that in a good year. This reflects the situation in Wales as a whole, with the general increase since the early 1990s. The map shows they can be scattered well beyond the sites monitored for the Wetland Bird Survey. However, Marloes Mere and Castlemartin Corse are the most likely places to find them.

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.

Most recent ringing recoveries of birds shot in Wales show they are coming from (or moving through) the Netherlands, Denmark, Sweden, Latvia and Estonia. However, studies at Orielton Decoy in the 1930s showed that some of our birds came from breeding grounds such as the Volga and Pechora rivers on the western Siberian Plain.

Larus argentatus – GWYLAN Y PENWAIG – Breeding resident and winter visitor

Updates to the Wetland Bird Survey counts for this season.

Counting gulls for WeBS is optional, and has only been regularly included at Pembrokeshire sites since 1993. Gulls are still not counted on a few sites.

Note that totals for any month this season may be updated as more counts come in.
