March 2018

The most remarkable thing to say about March’s count is “it was cold”. Bitterly cold with a strong easterly wind which, given the east west alignment of a lot of the estuary, meant there was nowhere to hide. There were no record counts this month, and just one bird hitting a winter high with nine purple sandpipers at New Brighton marine lake. The record 38 sanderling at Eastham last month had stuck around with 36 still present.

The whooper swans at Frodsham were not seen but six whooper swans were seen at New Ferry, flying down the river and then seen a short time later at Birkenhead Docks.

Canada goose number have remained fairly constant at about 2.500 since October. 400 pink-footed geese were a sign these birds are using the estuary regularly and not just for roosting at night. All ducks species except gadwall had halved since last month as they move off to their breeding grounds.

Of the waders, apart from the sanderling the most remarkable wader was a lapwing. Shaun found a dead one with a ring on. it was ringed in June 2002 as a nestling so it was nearly 16 years old. I know waders can be quite long lived, but a brief internet search has shown their average lifespan to be 4 to 6 years with the oldest bird being 24 years, so 16 is a good age for this bird. It is also a local bird, being ringed at Western Marshes Frodsham. However, the gird reference given is somewhere near Nantwich, so something is clearly wrong there and I suspect it was born on Weston Marshes, Frodsham ie within a mile of where it died!

Dunlin numbers had dropped from 40,000 to 10,000, which is to be expected. 1,400 black-tailed godwits were just a couple of hundred less than last month. Two common sandpipers were a sign that spring is on its way. 2,000 redshanks was our third highest this recording period.

Six raptor species is to be expected this time of year. Pipits included five rock pipits on Manisty Marshes and a water pipit at Hale. I think the cold weather and strong wind meant birds were in cover wherever possible and counting conditions were not ideal.

Thanks to everyone who came to the indoor meeting, we had seventeen people.

I can’t believe we continue to break records each month. This month eight water rails, beating the previous seven, though I expect there are many more lurking in the reedbeds. 38 sanderlings at Eastham is more than double the previous record of 18. However, the most significant record was turnstone. We recorded 546 which is the first count that exceeds the national significance threshold of 480. I had long suspected that the mussel beds and rocky areas around from Eastham to the Narrows and the Liverpool waterfront had good numbers of turnstone that had previously been unrecorded. This month we had very good coverage of the estuary. The majority of these were at New Brighton Marine Lake and so some might be feeding outside the estuary, but I suspect most will be feeding in the estuary at low tide.

Twenty four whoopers and two Bewick’s swans were about the same as last month, but only seventeen mute swans is well down on last month’s sixty four. 740 pink-footed geese was our second count of over 700 this winter and shows that the estuary is now being regularly used by these geese. There were also four barnacle geese, but I can’t be sure they are wild birds. About 2,000 Canada geese is down on last month’s 2,600, but it did include a record 500 on the Weaver Estuary.

1,800 shelduck is a significant increase on last month’s 500 and is the largest count since we had 7,000 birds moulting in August. This month’s count was of national significance. Only 500 wigeon was half last month’s. 1,400 teal was less than last month’s 2,200. 102 pintail was our highest count since 2005, but hardly suggests a revival for this species: the Mersey was once the best place in the UK for them. Shoveler at Frodsham had fallen from last month’s internationally important count of over 400 to just 152.

908 oystercatchers was the highest count this winter doubling the 500 seen in August. Our first returning avocet of the year was seen near the Weaver Sluices. The most significant wader count was grey plover. 544 is above the nationally important threshold, something we did not achieve in the last two winters. 40,000 dunlin were back to around there more normal levels after two winters with over 60,000 followed by a leaner winter than usual this winter. They were congregating and performing well off Stanlow Point. 1,700 black-tailed godwits was the highest count since July, they are obviously making their way back north; spring is on the way! 1,122 curlew was the highest count this winter but was below our 5 year average of 1,999 and below the nationally important threshold. 1,500 is nationally important for redshank which was similar to last month and finally a new nationally important count of turnstone was very welcome.

Thirteen little egrets meant they were surprisingly scarce after last month’s 49. Two great-white egrets were seen together.
In total six species of raptors were seen by me, and those counting at Ince Marshes, seeing all six. Merlin put on a very good display with two fighting in the air.

January 2018

The weather was miserable, continual rain tested waterproofs and it was cold - freezing in fact. However, we did manage to break two records. Last month’s record equalling six jack snipe was surpassed by a new record of twelve jack snipe flushed from Manisty Marsh by myself and Elliot. The other record was 81 greylag geese counted by John Gascoyne at Frodsham, beating the previous record of 54. Although probably feral birds there is a greylag goose that hangs around with the whooper swans which may well be a migrant from Iceland. The other remarkable count was our first nationally important count of teal for nearly two years with 2,200 which was just 100 more than the nationally important threshold but well down on our 5 year average of over 4,000.

62 mute swans was the highest this winter as were 25 whooper swans. Two Bewick’s swans were the first of the winter. 2,600 Canada Geese was almost exactly the same as December. 500 shelduck were down 100 on last month and the first count not of national or international importance. 1,000 wigeon was the same as last month. 418 shovelers was our first internationally important count actually on a webs count. Sixteen goldeneyes was the highest this winter.

49 little egrets was our third highest count ever and was nationally important. Three great egrets is average. 1,200 golden plovers were the highest this winter, though slightly below our average maximum. 23,000 dunlins was 7,000 down on last month, well below our average of 50,000. 1,400 redshank was similar to last month and was nationally important. There was a woodcock seen at Runcorn Sands.

The best bird for me was a ring-tailed hen harrier that I could just make out through the murk and my rain soaked binocular lenses. This was the second one on a WeBS count this winter, a bird that is not annual on Mersey WeBS counts.

The following weekend we did a low tide count. The weather was better and the mudflats were heaving with birds, particularly waders like dunlin, redshank, curlew, lapwing and golden plover.
