    Wetland Bird Survey 2016/17 

Wetland birds on Hilbre Richard Smith

Both the National and Dee Estuary Wetland Bird Survey (WeBS) Reports have been published for 2016/17. 

The National data can be accessed here ; it is presented both by Site and by Species and records go back for several decades. There is also a written report which has many fascinating articles, here is the list for 2016/17:

Below are a few tidbits from the Reports which I hope you find interesting:

North-west Estuaries Super-site

This map, from page 12 of the national Report, really brings home the importance of the group of estuaries in North-west England with the Duddon Estuary in the north, then Morecambe Bay, Ribble, Alt and Mersey with the Dee estuary in the south. This super-site typically hold over 500,000 birds in the winter, similar to that other super-site The Wash and north Norfolk coast, and is particularly important in cold winters when North Sea coasts are frozen, as in March 2018.

Good Wildfowl Numbers

Despite 2016/17 being mild and dry good numbers of Wildfowl were present both on the Dee Estuary and Nationally, presumably much colder weather on the continent pushed them west. On the Dee Estuary Pink-footed Geese reached a landmark 10,564 in March with large flocks on the marshes and small flocks becoming wide spread in fields around the estuary, it was only 2008/09 when the max WeBS count was just 329! There was also a record number of Brent Geese with 402 in November after several years when numbers were stuck around 250.  The max Wigeon count was 7,677 in December, the second ever highest WeBS count here, there were also good numbers of Pintail, Shelduck and Teal. The Dee Estuary, or more accurately the Liverpool Bay area off the estuary and North Wirral, had the highest counts of Common Scoters in the country with massive numbers in 2016 including 36,000 in February and 40,000 in October.  

Barnacle Geese

Feral Barnacle Geese family at Caldy Richard Smith

On the Dee Estuary there is a small resident population of Barnacle Geese which breed at Caldy Wildfowl Collection, usually around 12 birds. But occasionally we get ones and twos, or even small flocks, elsewhere on the estuary and in the winter of 2016/17 between 22 and 40 were regular at Connah's Quay Reserve and nearby sites. A long time ago, and we are talking about 150 years here, the Dee Estuary was known for it's wintering Barnacle Geese. So are these birds we are currently seeing the long awaited return of wild birds? Sadly the answer seems that it is very unlikely.

Up until some recent work, reported in the 2016-17 WeBS Report, we thought there was a real possibility that some birds were wild as there was an increasing number of Barnacle Geese wintering on the Dyfi Estuary, not too far from the Dee. 

I quote from the article Where do the Dyfi Barnacle Geese breed?:
"The Dyfi Estuary in mid-Wales is known as a long-standing haunt of the Greenland White-fronted Goose. From the 1990s Barnacle Geese began over-wintering at the Dyfi. It seemed likely that this flock were from the Greenland population of Barnacle Goose, and had followed White-fronted Geese to the site."

With numbers rising to between 300 and 400 on the Dyfi over the past few winters, and approaching the Nationally Important Threshold, it was decided to try and determine the origin of these birds through colour ringing. It soon became clear that these birds were feral and bred in the Lake District. As well as spotting ringed birds there was also good correlation of numbers between the two sites, and of departure and arrival times. Perhaps a disappointing outcome but still a fascinating migration, if somewhat shorter than flying from Greenland to Islay. As well as these birds there are feral Barnacle Geese both breeding and wintering in nearby Lancashire, probably at least 100 birds, and it seems likely that some of these wander south to the Dee Estuary. So the conclusion from all this is that any Barnacle Goose seen in our area is almost certainly from the feral population.


Given the high wildfowl numbers it's something of a surprise that wader numbers were relatively low. But Oystercatchers bounced back to close to the five year average, with 20,857, after very low counts the previous year. At 11,158 Lapwing numbers were the highest since 1994. Knot numbers were disappointing with a max of only 8,481* but nationally Knot counts have been fairly steady and for 2016/17 include a remarkable 205,161 counted on the Wash in October 2016, a record high for that site.

* Knot numbers for the Dee high tide WeBS counts do tend to be under estimated mainly due to disturbance at high tide roosts, particularly Hoylake. It doesn't help that counts take place on a Sunday when the beaches are busy with people.

       Colour Ring Report - Knot Special

                                Knots being ringed at Altcar on September 22nd 2017,  Phil Woollen

September 22nd marked the anniversary of the first catch of Knots at Altcar (just south of Formby Point) which were ringed with an Orange flag over a pale blue ring (usually shortened to OflagP). 519 Knots were ringed, since then there have been a remarkable 2,440 readings of those Oflags including 1,199 readings here on the Dee estuary and north Wirral shore.

As the years progress the continuing reading of these rings will become more and more important in order to gain a better understanding of their movements including the different migration strategies of individual birds, as well as their longevity, breeding success, survival rates etc. In the meantime the year they have been studied so far has revealed some fascinating movements. We saw a definite movement of feeding birds with Formby/Crosby used almost exclusively in October but by December nearly all had moved to Thurstaston. By February and March far more birds were feeding at West Kirby but with Spring the birds returned to Formby/Crosby. There was then an obvious northward movement and birds were seen around Morecambe Bay, north-east England then both the Outer Hebrides and the Orkneys. In May 82 Oflagged Knot were recorded in south-west Iceland which is used as a staging site before they move on to Greenland and northern Canada to breed.

Many immature birds don't make this northward journey. Some years they spend the summer in the Ribble and Alt area but in 2018 they dispersed around the Irish Sea with Oflagged birds spotted at several locations on the east coast of Ireland as well as Walney Island by Morecambe Bay.

The adults had started returning by mid-July and we started seeing Oflagged birds at Formby and Crosby. There were rumours of a bad breeding season but that turned out to be false (see  'Have Arctic-breeding Waders had a poor Breeding Season?') with many juveniles arriving through August. Although we did see a few Knot on the Dee estuary/North Wirral we didn't see the first OfP until September 21st, and, up until the end of September, we've seen a pitiful three Oflagged birds compared to several hundreds over at Formby/Crosby! But small numbers of Knot over here in autumn is normal, and we won't see the big numbers until November. Other returning Oflagged Knots have turned up on the Waddensee, a major moulting site for this species, and at both Snettisham and Titchwell on the Wash. 

Below is a history of four OfP Knots:

West Kirby on February 21st, 27th and 28th.
Sao Miguel, Azores, on September 22nd 2018.

The record on the Azores was totally unexpected and is the first BTO ringed Knot recorded there. We can only speculate how it arrived on the Azores with the few Knot that find their way there normally being the Rufa sub-species which migrate between the Canadian Arctic and South America. I quote Knot expert Jim Wilson (who is also coordinating many of the colour ringed Knot projects, including OfPs) - "One scenario is that it had migrated South into the wrong flyway - west Atlantic Flyway. We have 3 records of knots staging in Iceland - turning up in the Autumn on the major staging sites at Mingan at the mouth of the St Lawrence, Canada. If it then corrected its course to the correct course, SW, then it would head out over the Atlantic and could land up in the Azores. Of course it could have simply got blown out over the Atlantic on its route between Greenland/Iceland and Europe."

Many thanks to the 'Knot Oflag Team' and others for all the records, specially Jim Wilson, Steve Hinde, Peter Knight, Rose Maciewicz and Richard du Feu - and even more thanks to the ringing team which have now ringed around 1000 Knot at Altcar which will keep we Colour Ring enthusiasts busy for a few years!

Several other colour-ringed species were observed during September and these will be reported in the next newsletter.

September Bird News

                       Curlew Sandpipers at Burton Mere Wetlands, September 23rd Carole Killikelly

Although numbers of birds weren't big it was still a classic September with several Curlew Sandpipers recorded from the 9th onwards plus strong winds bringing in Leach's Petrels, Grey Phalaropes etc. Max count of Curlew Sandpipers at any one site was four, at Burton Mere Wetlands, Parkgate and Hoylake, with birds also seen at Heswall and Connah's Quay.   

Single Leach's Petrels were observed at Hilbre and Hoylake earlier in the month but it was overnight gales on the night of the 20th, and during the 21st, that brought good numbers and they were seen from New Brighton to Hilbre, max count 15 at the latter site. They were still passing through the following day and Hilbre again had the highest count of seven. In addition at least a couple of Long-tailed Skuas were seen together withseveral Grey Phalaropes (up to 5?), Great Skuas, Arctic Skuas, Manx Shearwaters, a Sabine's Gull and a Roseate Tern.

              Manx Shearwater from Hilbre, September 22nd  Steve Williams (Hilbre Bird Observatory)

A juvenile Pallid Harrier was spotted over the marshes between Parkgate and Burton on the 4th and was recorded up to the 6th and again on the 16th and 17th. Two Spotted Crakes were at Shotton whilst the one at Burton Mere Wetlands showed really well from the Reception Hide. A Chough was an excellent record for Hilbre on the 16th.

Marsh Harriers were recorded daily, they seemed to have switched their roost site from Neston reedbed to Parkgate, the highest definite count was eight but I wouldn't be surprised that total numbers are already in double figures. Up to four Spoonbills and eight Great Egrets have been at Burton Mere Wetlands.

During glorious weather at the end of the month Pink-footed Geese were flying into the estuary by the hundreds, a fantastic sight for those up early enough to see it.

On September 10th this Peregrine was seen hunting overhead at Burton Mere Wetlands, resulting in everything taking off from the scrapes, see below!    (both photos by Jeff Cohen)

What to expect in October

October is the month for visible migration, or Vis Mis as it's normally called by birders. To see what can, given the right conditions, be a spectacular movement of birds you need to be on the coast at first light. A light to moderate south-east wind is best, preferably with cloud cover and a slight mist with notable hot spots being Leasowe Lighthouse, Red Rocks, Hilbre, Thurstaston and Point of Ayr. What you are looking out for are mixed flocks of finches (usually mostly Chaffinches), Starlings, Redwings and Fieldfares among many other species which will be moving south along the coastline. For further details see the article 'Visible Migration'.

Prolonged north-westerly gales, especially early in the month, will result in the usual Leach's Petrels, selection of Skuas, Grey Phalaropes and Sabine's Gulls - although numbers are likely to be smaller than during September gales. Both wader and wildfowl numbers will increase and on high tides these can be a fantastic sight.

On the marshes there will be plenty of Marsh Harriers and Short-eared Owls, hopefully both in double figures, with smaller numbers of Hen Harriers.

We are more or less guaranteed a good selection of rarities this month - recent years have included Melodious Warbler, Yellow-browed Warbler, Pectoral Sandpiper, Rose-coloured Starling, Olive-backed Pipit, Richard's Pipit, Slavonian Grebe.....................
