THE CURLEW SANDPIPER

For the inexperienced birdwatcher it is easy to mistake the Curlew Sandpiper (Calidris ferruginea) for a Dunlin, it's nearest relative. However, with it's longer legs, neck and curved bill the Curlew Sandpiper is much more elegant - in fact altogether a delightful and intriguing species. 

The Curlew Sandpiper breeds in the high arctic of Siberia, wintering in Africa south of the Sahara, India, south-east Asia and Australia, it passes through Britain as a scarce passage migrant - most birds migrating straight over land through mainland Europe and Asia (1). Just a few adult birds are seen both spring and late summer, mostly on the east coast but with a few turning up on the Dee Estuary. This year (2000) has been particularly good for adult Curlew Sandpiper - during August at Hoylake single birds were seen on six days, two on another day and a remarkable ten on the 29th, single adults were also seen at Heswall on two separate days.  

But it is the juvenile birds which are particularly fascinating. They turn up late August and September looking brand new with their fresh plumage, well behind the passage of their parents. You might be the first human being they have seen and consequently they can be remarkably unwary. Numbers on passage each year is very unpredictable, dependent on both breeding success and wind direction during migration. It is thought that the survival rate of the chicks is linked with the lemming cycle, the Arctic Fox being more inclined to eat lemming when they are plentiful.

Curlew Sandpiper - Distribution and Migration Routes

An east wind during September is sure to bring the young Curlew Sandpipers, as yet inexperienced in the art of bird navigation. Here is a table showing the places on the Dee Estuary they have been seen over the past few years with numbers present. They particularly like feeding in muddy areas, such as the boat anchorage at Heswall - just off Sheldrake's Restuarant. Note that in addition to those shown below a good place is the Point of Ayr, but I'm afraid I don't have any numbers for that site.

Table shows largest single count of Curlew Sandpiper in each location (all sightings Sept. or early Oct.)

August Bird News

TOP OF PAGE

August was an excellent month, pride of place going to a record count of 97 Greenshank on Boathouse Flash at Parkgate Marsh (part of the RSPB Gayton Sands reserve). Curlew Sandpipers were also much in evidence with a very good passage of both adult and juvenile birds (see article on Curlew Sandpipers above). Particular good numbers were seen at Hoylake and Meols, both with counts of 30, Heswall with 13, Parkgate 19 and Inner Marsh Farm with 17. As usual most of these birds were juveniles but ten adults were seen at Hoylake on the 29th, four of these were in summer moult and six in winter plumage - a plumage rarely seen on the west coast of England.

There has also been a very good passage/return of the more common waders. 3000 Dunlin (Hoylake), 435 Sanderling (Hoylake), 1200 Ringed Plover (Hoylake), 2730 Curlew (Heswall) and 5733 Redshank (Heswall) were the highest counts. The Redshank count at Heswall must be one of the highest ever August counts there.

Three Arctic Skuas were seen off Hoylake shore for several days and single Pomarine Skuas off Hoylake and Point of Ayr, were another five Arctic Skua appeared at the end of the month. Four Mediterranean Gulls frequented the North Wirral shore. Tern numbers were well down on July for most of the month but 30 Little Tern were seen at the start of the month and 438 Common Terns at the end - all at Hoylake.

Raptors included some great views of two Marsh Harriers. These spent most of the time at Inner Marsh Farm and Burton Marsh but one put in a visit to Heswall marsh were it put up 32 Grey Heron. A Hobby and 5 Common Buzzard were seen on the same day at Inner Marsh Farm. Peregrine Falcons were observed almost daily at Hoylake and Heswall, and the local Kestrels must have had a good breeding season with at least seven hunting over Parkgate marsh. 

Other notable birds were single Little Egrets at Oakenholt, Point of Ayr and Hoylake, Subalpine Warbler (Leasowe), Tree Pipit (Hoylake) and Black Redstart (Hilbre).

Many thanks go to Jane Turner, Steve Williams, Cathy McGrath, Mark Feltham, Anne Lister and Stephen Menzie for e-mailing me their sightings during August. I rely on the goodwill of people like this, unlike some commercial sites I cannot offer financial inducements!

Migration Watch 2000

TOP OF PAGE

Every year since 1992 the various Ranger Services in the Mersey and Dee Estuary region have been staffing visible migration watchpoints. This brings to the public's attention one of the most fascinating aspects of bird behaviour. Each autumn vast numbers of birds pass through our region unseen but a few notable species gather together in large numbers. At certain points they become channeled along well known migration corridors. Each year produces surprises, such as 1999's Woodlark and Common Crossbills at the public watchpoints on the Wirral, but the real thrill is seeing the massed passage of regular migrants such as the winter thrushes as well as the various species of finches and buntings. For full details of venues contact Wirral Country Park at 0151 648 4371/3884. The selected dates and times of the migration watches are:-

Start Times: 

Sunday 24th September 7:00am
