Low Tide Wetland Bird Count 1996/97

The Dee Estuary constitutes the largest and most important estuary yet covered by the WeBS low tide counts scheme which take place once every seven years. These are infrequent compared with the usual WeBS core counts, which take place at high tide, because of the extra effort involved in counting birds over such a vast area of marsh and mud-flats. The counts take place monthly between November and February.

Dee Low Tide Count

The two counts, at high and low tide, tell a fascinating story of birds roosting in one estuary and feeding in another, and of how the different species spread themselves across the estuary. Taking the above map as an example this illustrates the distribution of two of the most important bird species on the estuary, Pintail and Knot. Their ranges are completely separate with Knot keeping to the mudflats of Dawpool, East Hoyle Bank and Mockbegger Wharf (MBW). A mean count of 33,000 Knot was counted which ties in quite nicely with the 30,000 maximum high tide count. This contrasts with Pintail which are found exclusively on the salt-marsh, in particular on the Welsh side off Flint. The numbers of Pintail counted at low tide were only about a quarter of those seen at high tide presumably because many were "lost" in the salt marsh as the tide goes out.

The north Wirral coast (East Hoyle Bank and Mockbeggar Wharf) was found to be the major feeding area for Ringed Plover, Grey Plover, Sanderlings and Bar-tailed Godwit. Oystercatchers and Dunlin were widely distributed throughout the mud-flats of the estuary and Curlew and Redshank inhabit both the mudflats and salt-marsh.

The Bar-tailed Godwits are of particular interest, counts at high-tide on the Alt Estuary, just north-east across the Mersey from Wirral, were found to be 9,000 in 1996-97 whereas the low-tide count was only 440. This is almost certainly due to many of these birds flying across to the north Wirral shore at low tide to feed. In contrast Black-tailed Godwit are found in the inner estuary both at low and high tide off Heswall and Flint.

The study of how birds distribute themselves across the estuaries of Liverpool Bay with the ebb and flow of the tide is a fascinating subject. A body of enthusiastic birders who are currently performing this very study are the Liverpool Bay Wader Study Group.

The WeBS counts (both high and low tide) include the north Wirral shore as part of the Dee Estuary. This makes sense as there is no physical break between the two. For this reason I have decided to also include the north Wirral shore within this Web site. I already include Hoylake but will now also include the whole of the shore up to the start of New Brighton promenade. I will not include the mouth of the River Mersey because in no way can I claim that to be part of the Dee! I will add this extra page to the Web site prior to the 1999/2000 Winter season.

The above is a summary of an article published in the Wetland Bird Survey (WeBS) 1996-97. The book can be purchased from NHBS for 15.

Up to 15 Whimbrel are now being seen/heard daily along with a small remaining flock of 5 Purple Sandpipers soon to leave for their breeding grounds.


April Bird News
The summer migrants continue to pour in, the first Willow Warblers were seen at Hoylake on the 2nd and first swallow, also at Hoylake, on the 8th. In fact the 2nd was a particularly good day at Hoylake as in addition to 6 Willow Warblers were a Ring Ouzel, 25 Wheatear, 25 Sand Martin and 6 Tree Pipits. A Black Redstart was observed at the Point of Ayr on the same date.
Another migrant passing through has been the Osprey with two sightings at the beginning of the month, both at Inner Marsh Farm, and two at the end of the month, one at Burton marsh and the other flying north over Hilbre Island.
As usual Inner Marsh Farm has seen plenty of activity with two Spoonbill present all month, including one of the Mauritanian race. Up to 14 Spotted Redshank are also at the 'farm' along with a pair of Garganey, one Little Egret and a Little Stint. 1,200 Black-tailed Godwit have arrived at IMF, last year this was the UK's largest summering flock.
Other birds of note seen during April were 4 Shorelark at Gronant (the remnant of the over wintering flock) and a pair of Peregrine, Greenshank and Short-eared Owl at the high tide birdwatch at Parkgate on the 17th.
