MERSEY MUD MATTERS

QUESTION: How many calories are there in one cubic metre of lovely Mersey mud?

ANSWER: 4160, the same number of calories as 16 Mars bars. Yum! No wonder thousands of birds are willing to fly all the way from the Arctic to feed here.

The Mersey Estuary is an amazing place. It’s been vital for the economic prosperity for the area, an iconic part of our history and always stunning for wildlife. It’s a European Special Protection Area ( SPA ), a designated Ramsar site, and one of the four nationally designated Sites of Special Scientific Interest (SSSI’s)

Each autumn, birds arrive on the Mersey Estuary all the way from the Arctic . The estuary is a vital link in the chain of migration that sustains many birds through the winter. They choose the estuary as their winter quarters because it’s a sheltered site with an abundance of food. And it’s not just wintering species who love it on the Mersey . The estuary is also a popular and important breeding ground for skylarks and redshanks, as well as colonies of gulls.

Together with Morecambe Bay , and the Rivesr Ribble and Dee estuaries, the Mersey forms part of Europe ’s most important wetlands network for wintering and passage birds, hosting almost a million every year

Who feeds here?

49,000 Dunlin, 1,600 Curlew, 3,000 Teal, 10,000 Widgeon, 10,000 Shelduck, 11,000 Black Tailed Godwit, 5,5000 Redshank, 10,000 Lapwings, 2,500 Golden Plover and 1,300 Grey Plover.(approx figures,Wetland Bird Survey 2000-01)

A site is considered to be of international importance for any species of bird if it supports more than 1 per cent of the European population. The Mersey Estuary is internationally important for three species of duck and four species of wading bird and so qualifies as a Special Protection Area, a status reserved for only the most important bird sites in Europe. It also qualifies as a Ramsar site; a wetland of international importance. This recognises wetlands as vital links in a chain where migratory birds can stop and refuel en route between their breeding and wintering grounds. To be considered nationally important, a site must regularly support more than 1 per cent of the UK population of any species.

The River Mersey supports a typical estuarine fauna. Invertebrates include such species as pink and green ragworm, white catworm,  lugworm in sandy foreshores, shore crabs, small Hydrobia snails and shrimps  (as well as sand gobies) in small pools, mussels, prawns, sea anemone in rock pools along Egremont shore, Korean sea squirts and common jellyfish in some of the docks whilst damselfly, dragonfly and caddisflies are found further up river.

Plant Species occurring on the salt marsh  include, for example, sea couch, common salt marsh grass, halberd-leaved orache, sea aster, scurvy grass, annual sea-blite, sea plantain, sea milkwort and sea clubrush.

Water quality improvements now means the Mersey supports a wide range of fish species including Salmon, Trout, Lamprey and Dace. The increase in numbers of fish in the river has encouraged a number of other animals to return to the estuary. These include porpoises, grey seas and even octopus!

Liverpool RSPB's BIG New year birdwatch

After getting up nice and early with a scrapping of ice from the windscreen, it was up to the Speke/Garston LNR for Liverpool RSPB's BIG New Year Birdwatch and the start of many peoples New Year birdlists. Sunday compared to the previous days total washout, dawned cold, dry, sunny, with a slight breeze with little wind chill. 35 intrepid birders joined the throng eager to start the walk, ears pricked binos at the ready.

A great start even before the last boot was laced and the car park left we had seen Blackbird, Woodpigeon, L.B.B.Gull, Goldfinch, Flocks of Starling, a Grey Heron in flight and hunting Kestrel. Walking the path toward Garston shore we spotted Redwing perched in the trees, soon joined by 2 more of the Turdus species Mistle thrush and singing Song thrush. The Kestrel we had seen hunting earlier came to perch in the trees close to the path giving us great views of her sunlit plumage, she didn't seem to be bothered by the gawping humans 20 0dd feet away! Shortly after it was joined by the tercel, male and female together.

A Greenfinch was the last to be ticked off before we moved onto the river birds. Along the shoreline probing the mud ( MERSEY MUD MATTERS -website article) we found Redshank, Cormorant, Herring gull, Black Headed Gull, Curlew, Teal, Mallard, Lapwing, and a magnificent yet menacing Gt.Black Backed Gull. Overhead being mobbed by crows an unconcerned Buzzard scanned the reserve blow. In the breeze swept reeds between the mudbanks and the path Reed Buntings flitted between the stalks, a Wren called out and was duly ticked. Back on the river we had 3 Shelduck bobbed along, quickly out done by a flock of Dunlin, twisting and turning in flight along the shore looking for the best bit of mud to alight on. A Turnstone was observed, doing what it does best, turning stones, piping Oystercatcher completed the picture.

Turning away from the shore scanning the fields around the warehouses, we ticked off Magpie, Collared Dove, and Carrion Crow. And a then at mega for the day the strange distant bird acting like a kestrel turned out to be a Peregrine perched onto the corner of the B&M building, then swooping through the buildings and onto Speke Hall Woods. Spreading out for walk through the marshy grassy area, our stealthy band of 'beaters'! Flushed out a marvellous Brown Hare, a covey of 5 Grey Partridge, a Skylark, a Snipe and a Meadow Pipit.

Moving on to our second stop of the day we re -grouped by Sefton Park Lake (Along with a large proportion of Sunday strolling Liverpudlian families enjoying the sunny weather- the swans, geese and ducks were all well fed that day) The tick list grew, as we added feral Pigeon, Mute swan, Common gull, Coot, Canada goose, Moorhen, 4 gorgeous Little Grebes, and a sprightly lakeside Grey Wagtail. Leaving the lake and into the trees we espied, along with the resident Grey Squirrels and Rats, Blue tit, a good view of a Ring neck parakeet (a first for many of our group), Long tailed tits, Great tits, hunting Sparrowhawk, Robin, Chaffinch, and a posing Jay perched on a branch probably keenly watching where the resident Grey’s were burying their monkey nuts. A Pied Wagtail and 4 Mistle thrush's were on the playing fields avoiding the footballers.

A short walk over to nearby Greenbank Park gave us a Tufted duck, a Jackdaw, another sighting of the Ring necked Parakeet and a handsome male Goldeneye on the lake.

Back to our cars for a quick drive to the Black Woods in Childwall gave us Nuthatch, Coal tit, female Great spotted Woodpecker and male Great spotted woodpecker as "Ged" our Woodpecker expert pointed out at the last indoor meeting 'Red on the crown'! Stock dove and to finish off as the sun was going down we got lovely Brambling.

60 birds in total, not bad for a day in local parks.
