The lake was built in 1899 for people to boat on, and was doubled in size in 1987. Boats, of course, mean disturbance; but as that is the lake's purpose we shouldn't really complain when birds are disturbed, although that doesn't stop us! It is called a Marine Lake as it is filled with seawater and at spring tides regularly gets flooded as it is immediately adjacent to the Dee Estuary. At times when there is little or no wind, and therefore no sailing, it can attract good numbers of duck - mainly Goldeneye and Red-breasted Merganser. Although never a site to attract mega rarities or large numbers of birds it does have the advantage of having all round access to birders allowing for some wonderful views and good opportunities for photography. As well as the duck already mentioned we have seen Scaup, Pochard, Tufted Duck, Long-tailed Duck, both Whooper and Mute Swan, Shag, Great Northern Diver, Red-throated Diver, Great Crested Grebe, Glaucous Gull, Little Gull and Mediterranean Gull over the past few years, as well as one or two Leach's Petrels flying over during north-west gales. This last month (Jan 2010) was unusual as we had a prolonged period of very cold weather coupled with no wind, this meant inland waters were frozen and there was no sailing on the lake; consequently much larger numbers of ducks were present than what has been normal over the past few years. I thought it would be interesting to put the numbers of Goldeneye and Red-breasted Mergansers we saw into a historical context, as follows.
Looking at Cheshire and Wirral Bird Reports going back as far as 1964 there have always been good numbers of this lovely duck on the marine lake, there was a max of 38 in 1964 which reached a high of 72 by the end of that decade. Counts have always been very variable, for example there was a max of only four in 1974 yet 40 the following year, 52 in 1983 dropped to only two in 1984. No doubt the amount of disturbance coupled with the weather will have had a big part to play in this variability.
Although the 30 seen on 9th of January this year was the highest since 2000 historically it was nothing outstanding with seven years since 1987 exceeding it. With most, if not all, inland waters frozen over perhaps it is surprising we did not get more birds but no doubt there will have been many more on the sea. The highest ever recorded on the marine lake according to the Cheshire and Wirral Bird Reports was 'up to 100' in 1989 during an exceptional extended period of calm weather when no wind surfing was possible. That must have been quite a sight!
Although large numbers were recorded on the Dee Estuary during the 1960s and 1970s (max 250 off Caldy in 1965) this species seemed to be virtually unknown on the marine lake at this time. 19 in 1977 was regarded as 'exceptional' and even by 1985 18 was regarded as 'an unusually large flock'. After the lake was extended in 1987 there were no records until 1993 when a high count of 43 was recorded. As can be seen in the graph below since then max numbers varied from year to year but never bettered the 1993 count until we got 46 on Jan 11th this year. When I saw them the majority were in one big flock although I missed what others saw, birds cooperatively fishing by herding the fish into the lake wall. Usually numbers aren't large enough for this fascinating behaviour.
I find it a bit of a puzzle as to why there were such large numbers of Red-breasted Merganser last month, this species is almost exclusively marine in the winter so would not have been affected by iced over fresh water. May be they were attracted by the presence of the other ducks together with the nice flat calm water and complete lack of disturbance for several days, and there must have been plenty of fish! Although the count of 46 was higher than any recorded in the Cheshire and Wirral Bird Reports (i.e. since 1964) it appears not to be a record high count. Eric Hardy reported in The Birds of the Liverpool Area that birds were frequent on the lake before the second World War with 'about 50' in Dec of both 1937 and 1938.
There was one other species of duck in good numbers on the marine lake last month, Tufted duck - which reached 29 on Jan 10th. Normal yearly max of this largely fresh water species is just two or three. But 29 is tiny compared with inland numbers with 500 at Woolston Eyes in Cheshire a fairly typical number and 135 were on Shotwick Boating Lake in January 2009. Our small flock of 29 soon disappeared, this was before the thaw so it is interesting to speculate where they, together with the inland flocks, went to - presumably a lot further south!

4. Records sent directly for inclusion on this Website (www.deeestuary.co.uk).
Firstly, all the records which are NOT County rarities which are sent to myself (Richard Smith) for inclusion into this website are sent on and included in the Cheshire & Wirral and North-East Wales data bases, and these are then sent to the compilers when writing the Bird Reports. Obviously, as I cannot fill in a rarity form for birds I haven't seen, I don't send in rarity details - you will have to do that yourselves! It is VERY IMPORTANT to fill a rarity form in and get your record accepted by the relevant rarity panel - otherwise your record will not be official and it will be lost to posterity.
Please feel free to submit your records directly,
that way you will get your name mentioned rather than being lumped in with
the 'Dee Estuary Website', but more importantly it would be greatly
appreciated if you could submit any additional records, including rarities,
For submitting Cheshire and Wirral records, including rarities, see details in the CAWOS website - www.cawos.org - click on 'recording' then 'submission of records'.
For submitting for the North-East Wales area (Flintshire and Denbighshire) see the Clwyd Bird Recording Group website - www.cbrg.org.uk - and click on 'will you help by submitting records'.
I should like to add that where you have managed to take a photograph of a bird which is a County Rarity, of whatever quality, please include it with the description. If the photo is of reasonable quality then that alone will often be enough to get it accepted. But please include any features of the bird which the photograph may have missed, together with details of behaviour, precise location etc.
This Slavonian Grebe was one of two which came close into Flint Castle at high tide on the 1st. These weren't the only grebes to be seen as a massive 455 Great Crested Grebes were off Meols on the 4th. This large flock must be one of the largest in the country, but very difficult to count as they are so far out. 21 Scaup were present on the same day, much closer to the sea wall, with 39 off Hilbre on the 16th; an excellent count for this species. 62 Red-throated Diver were off Hilbre also on the 16th. A Velvet Scoter was off Hilbre on a couple of days as was an Eider and three Goosanders. As well as the ducks already mentioned in the above article West Kirby Marine Lake had a maximum of 13 Shags with two Common Pochard a rarity here.
The big story of the month was the prolonged cold spell, like the rest of the country we had lying snow and freezing daytime temperature for several days - unusual for our normally mild maritime climate. During this spell we saw a marked influx of Woodcocks with 11 reported in just 12 days, normally we would expect just four a five reports a year. This species is very secretive so there is little doubt there would have been many more hiding in the woods and scrub. Fieldfares appeared to be everywhere with Redwings slightly less so. Bramblings also increased in numbers with a flock of 30 at Inner Marsh Farm. There were several days of crisp, sunny and windless days when it was a privilege to be down on the shore. I spent many hours at Thurstaston watching the Black-tailed Godwits (max 1,680), Knot (max 15,000) and Pintail (max 960). Towards the end of the month many Black-tailed Godwits started feeding in the nearby fields, by then ice free and presumably full of earth worms! Over 1,000 Black-tailed Godwits were also at Point of Ayr.
There were good numbers of Pink-footed Geese around. 600 or so are resident on the marshes of Neston and Parkgate, but we also saw many flocks passing through with 1,200 observed from Hilbre on the 10th the biggest flock reported. In this flock were 10 White-fronted Geese, a rare bird in our area, five were in a 'Pinkfoot' flock feeding on the Hoylake Langfields on the 19th. Brent Geese reached a max of 157.
A Shorelark was on the beach near Gronant towards the end of the month, and a single Snow Bunting further towards Point of Ayr. Two Snow Bunting were on the beach at Hoylake for a couple of days. A female Black Redstart was reported on the sea defences near Leasowe Castle on several dates, but was very elusive, another was on Burton Marsh on the 31st. Bitterns are always elusive but one showed well a few times at Inner Marsh Farm. Two Spoonbills were on Parkgate Marsh on the 9th, with a single seen at several locations throughout the month. Also at Parkgate have been the usual Short-eared Owls, up to five, and four Hen Harriers which included a 'grey' adult male. A female Marsh Harrier was seen on several times.
The beginning of the month sees two very high tides predicted, given a decent westerly wind these should result in the sea covering the marsh at Parkgate and elsewhere. We should get some great views of Short-eared Owls in particular and the several hundred Pink-footed Geese which are spending the winter here will be brought a lot closer. Look out also for Hen Harriers, Water Rails and Jack Snipe.
February usually has a day or two of mild weather bringing a foretaste of the spring to come, resulting in our woodland birds bursting into song as well as skylarks in full song in the sand dunes and fields. Other signs of spring might well be the arrival of Avocets, these will be on passage on their way north to Lancashire where good numbers now breed. A south westerly wind might well bring us our first Gannets of the year out to sea.
Wader numbers usually remain high through much of this month and we often get an influx of a few Spotted Redshank into Inner Marsh Farm and Connah's Quay. There will be several hundred Black-tailed Godwit off Thurstaston although numbers might well drop through the month as they seem to like going to East Anglia before making their long journey back to Iceland to breed.
