The Knot (Calidris canutus) 
  


Martyn Jamieson
  This is the first of an occasional series featuring a specific species found on the Dee Estuary.

Watching great clouds of Knot flying in tight formation must be one of the most enduring memories of any visit to an estuary. As they turn seemingly as one, flashing grey and white in the sun, the flock, ten thousand strong, splits as a Peregrine dives through them - a wonderful sight.  

Two distinct populations of Knot pass through the Dee Estuary, those breeding in Canada and Greenland and the other breeding in Siberia. By far the most numerous is the Canadian/Greenland population which spend the winter here and the rest of Western Europe. The Siberian birds are only seen on migration on their way to and from West Africa, some even go as far as South Africa - however the majority of this population is thought to migrate further to the east. 

      Canadian Arctic/Greenland/                         North Central Siberia/
      West European population                         West African population

The graphs below show how the numbers and yearly distribution of Knot have changed over the years. Twenty to thirty years ago many Knot flew directly from their breeding grounds to the Dee to moult during the months of July to September. This was followed by a mid-winter peak as birds from further east (especially the Waddenzee) moved west fleeing from the cold continental winter and/or to find fresh supplies of food. The latest WeBS (Wetland Bird survey) data from 1993 to 1998 show that the moulting Knot no longer use the Dee in any thing like such numbers. Now they moult further east on estuaries such as the Waddenzee and the Wash. The Dee still sees the mid-winter peak as demonstrated by both the WeBS data and that from one of their main high tide roosts at West Kirby for 1998/99. However the figures for the winter just gone (1999/2000), which was mild both here and on the continent, show no mid-winter peak at all at West Kirby. The birds choosing instead to stay on the continent. 

Number of Knot on the Dee Estuary - Wetland Bird Survey data for the whole estuary and West Kirby high tide roost.  
Note that the WeBs data show the peak monthly counts over the five year period specified and data from West Kirby the peak count from each month. Both these counts are taken at high tide.

These high tide counts don't tell the whole story by any means. Firstly, low tide counts* carried out by WeBS show quite clearly that many Knot feeding on the Dee Estuary at low tide fly over to the nearby Alt estuary to roost at high tide. These birds are therefore missing from the Dee Estuary high tide counts. Secondly during migration the Knot pass through the area quickly, feeding at low tide then continuing their journey at high tide - again missing the high tide counts. A visit to the estuary during late April and early May will often result in the sighting of large flocks of birds feeding on the mud banks. Stand at Red Rocks at high tide and you may be rewarded by the sight of flock after flock passing you on their way north.

Voluntary Wardens needed at Gronant

Top
Those of you who have visited the Welsh Shore page will already know of Gronant on the North Wales coast between Point of Ayr and Prestatyn, and some of you may actually have been there. It is a beautiful wild area of sand dunes, marsh and beach. In the summer it holds the only Little Tern colony in Wales and the RSPB are appealing for voluntary wardens to help protect it. This will involve looking out for predators, especially crows, gulls and foxes, stopping holidaymakers and their dogs from walking through the colony and chatting to any interested passer by about the birds.

I've just volunteered so you might see me! The wardens will be required from end of May to beginning August.

If you're interested ring the RSPB at 0151 336 7681, mention this web site if you wish - I know they would be interested to know if this appeal is successful.

The Wirral Society

Top
The Wirral Society was formed back in 1928 as an environmental watchdog, with the object of protecting the natural beauty, architecture and flora and fauna of the Wirral Peninsula. For the last 70 years, the society have done their best to take an active role in preserving what makes Wirral unique, keeping a careful eye on any proposed plans or developments which they believe threaten what the society set out to protect, all those years ago.
