Northern Shelduck
Tadorna tadorna
Resident
Peak count 1st. winter period :- 290 off Little Eye February 16th.
Peak count moult period :- c. 800 flying south off Little Eye August 5th.
Peak count 2nd. winter period :- c.1,100 off Little Eye October 27th.
[The birds off Little Eye in August were probably moving to the newly
recorded moult site on the Mersey. Previous to the discovery of this site
the only known moulting areas in Western Europe for Shelduck were Heligoland,
between Holland and Germany, and Bridgewater Bay in south-west England. The
Dee holds Internationally Important numbers of Shelduck and is third, after
The Wash and the Mersey, in importance.]
Eurasian Wigeon
Anas penelope
Scarce winter visitor
10 January 1st, 17 on 6th. and 5 on 11th. all off Little Eye. 1 adult
male Marine Lake January 17th. 10 off Red Rocks October 29th. 2 off West
Kirby November 15th. 1 November 18th. 16 on Tanskeys December 21st.
[ Although Wigeon winter in Nationally Important numbers higher up the
estuary they are reported by the wardens only in small numbers and are
barely annual. The bird on the Marine Lake was unusual as this species is
particularly sensitive to disturbance. ]
Common Teal
A. crecca
Scarce winter visitor
Birds in flight were 1 January 6th, 2 January 11th, 2 September 27th. 2
in the saltmarsh January 26th., 2 on the tide February 21st. The first
returning bird was a single on the tide November 5th.
[This is the second most frequent ‘dabbling’ duck recorded by the
wardens and is found in Internationally Important numbers on the estuary.
Even with the amount of disturbance that occurs through the winter there is
usually at least one record a year from within the saltmarsh. Green-winged
Teal, previously regarded as one of the North American sub-species of Common
Teal, has now been split as Anas carolinensis leaving crecca and nimia in
Common Teal. An ‘armchair tick’ for many birdwatchers.]
Mallard
A. platyrhynchos
Scarce resident
Up to 3 birds were present throughout the 1st winter period. A peak of 10
males were on Red Rocks marsh on March 27th and a female was seen in the
dune slack on May 19th. + 20th. with 9 pulli. The peak count in the second
winter period was 7 on November 12th..
[ Although Mallard are notorious for nesting anywhere there was no
definite record of them doing so on site in the Cheshire Atlas. It is not
known if any of this years young were raised to fledging. Red Rocks marsh
was remarkable for breeding birds this year ( or was it just because the
area was so intensively covered through the year ?) ]
Northern Pintail
A. acuta
Scarce winter visitor
7 January 1st. and 11 on 6th. off Little Eye., 3 on the tide January
16th., 4 in flight September 24th., 2 October 11th., 14 December 11th. 7
December 21st.
[This species should be recorded with a higher frequency, and in greater
numbers, than it is, considering the size of the wintering population on the
estuary. Although the Dee is still the most important site in Britain the
numbers have declined over the last 10 years. If this trend continues the
wardens may record even fewer than at present.]
Northern Shoveler
A. clypeata
Scarce winter visitor
11 over West Kirby shore September 19th., 3 October 8th.
[Like many waterfowl Shoveler are infrequently recorded from the site and
the flock in September is probably a record for the site. Numbers have been
rising in the general area for the last five years or so and they are now
regular on Gilroy pond and are even being recorded from Ashton Park lake.]
Tufted Duck
Aythya fuligula
Vagrant
1 ( m. ) January 14th. on the Marine Lake. 3 ( 2 x m, 1 x f. ) over West
Kirby shore August 17th. 1 ( m. ) Marine Lake December 20th.
[Tufted Duck have always been extremely scarce in the wardening area. The
winter of 2000 / 2001 saw a massive rise in the numbers around NW Wirral
with a flock of up to 30+ moving between Ashton Park lake and Gilroy pond,
West Kirby. The last 40 years has seen a nationwide increase in both
breeding and wintering birds.]
Greater Scaup
A. marila
Scarce winter visitor
2 off Red Rocks October 28th. 18 on tide December 12th.
[Gone are the days when flocks of up to 200 birds used Caldy Blacks
through the winter but larger numbers than usual were in the area during the
second half of the year. The highest number of birds for over ten years for
the wardens.]
Common Eider
Somateria mollissima
Annual in very small numbers
1 ( m. ) Red Rocks September 24th.
[Eider are present each winter in the wardening area but only in low
single figures. The main site in the Dee is usually around Hilbre, probably
because feeding prospects are better.]
Common Scoter
Melanitta nigra
Rare winter visitor
Singles ( f. ) on January 11th, February 13th, 2 ( m. ) August 17th. off
West Kirby shore. A day count of 463 October 28th past Red Rocks was the
highest figure reported.
[ A good year for sightings inside the estuary but when compared to the
results of the Common Scoter survey carried out during the winter of 2000 /
2001 off the coast of Wales and in Liverpool Bay the numbers recorded from
the site barely warrant a mention. ]
