I've always been fascinated by bird movements,
particularly waders. Knot are probably the archetypal species when it
comes to movements so when I was asked by Peter Knight, who has been
studying Knots on the Ribble estuary and Formby coast, to take part in
a coordinated tracking of Knot between the Dee, Formby and Ribble I
jumped at the chance. I recruited my fellow wader enthusiasts Matt
Thomas and Steve Hinde, who were also eager to take part. I'll let
Peter take up the story:
I
organised a coordinated tracking of the Knot
through the highest spring tide of December 2016 (15th Dec,
9.9m 11.43am - Liverpool Gladstone Dock height and time). It
was
overcast, a bit misty with light southerly wind. Matt Thomas
and Steve Hinde were on the Dee estuary between West Kirby and Heswall,
Richard Smith covered the north Wirral shore,
I was at Crosby then Formby south and Ric Else was at Marshside
(Southport) then
1.5km S from Weld Road, Southport. We all used texting to pass around
information about the Knot flocks as it was happening, and the texts
themselves are a valuable record of the events and times, and thus
better than phone calls. As far as Richard is aware this is the first
such coordinated count.
Two days earlier (13th
Dec) the tide was lower at 9.6m and
16k roosted through the tide at Hoylake, but none were there or feeding
at Thurstaston on the 14th; however 10k were feeding at Leasowe at low
tide.
On 15th Dec all the
Dee and Wirral Knot (totalling 17k: 7k at Meols and 10k flew by
from further west - Hoylake) flew over to roost at Formby south (took
them about 5 minutes to cross over), managing to roost just south of
the warning sign for the rifle range, and there were 22k there in total
at high tide (as counted when a Peregrine flushed them all during the
falling tide). Ric had another flock of 9k that built up at Weld Road
just around high tide, but he had none earlier on at Marshside and it
isn’t clear where his birds were coming from – I didn’t see many/any
going north prior to high tide. At high tide most birds at both sites
were cruising around as drifting clouds up over the sea, but all landed
at both sites once the tide began to fall. On the falling tide the
Formby birds carried on roosting until I left about 4 hr after high
tide; very few were found back on Wirral; Ric’s birds started feeding
straight away and until he left the site – interestingly different
behaviour. I wonder if his birds are relatively new (and hungry)
arrivals from Waddensee.
So coordination worked
easily and
effectively, and showed a total of 31k Knot in the Ribble-Dee extended
site on that date. Two weeks earlier, on the lower spring tide
series, there
were about 10k in the Dee and only about 1.2k on the Crosby-Ribble
shore. So there looks to have been a big influx.
Peter Knight.
A
fascinating exercise. It confirmed what has been previously assumed,
that many of Dee estuary Knots on the highest tides fly all the way to
Formby/Alt estuary to roost. Interestingly, the 10k I saw flying past
me at Meols from the direction of Hoylake were not seen by
either
Steve or Matt who were monitoring from Thurstaston and Heswall
shore. It's possible they came all the way from Point of Ayr or,
perhaps,
had been in a sub-roost somewhere on East Hoyle Bank. In
addition
to the Knots described above Steve Hinde had 470 at Thurstaston before
high tide which flew over to Flint to roost. Perhaps with a future
coordinated count we should have observers both at Flint and Point of
Ayr as well, and one at Hilbre might be a good idea!
Many
thanks to Peter Knight for organising this coordinated tracking of
Knots and for letting me publish his account, and also Ric Else, Steve
Hinde and Matt Thomas for taking part.
A lot has
been written about numbers and movements of Knot (and other wader
species)
around the Dee estuary and North Wirral, and also disturbance issues.

Colour Ring Report
Top left and clockwise:
Black-tailed Godwit
GG-GL (Matt Thomas), Black-tailed Godwit YL-LX (Tim Kinch),
Dunlin
5PL (William Boyce), Black-tailed Godwit R8-WO (Matt Thomas).
The main frustration about logging colour-ringed birds is not staring
at Black-tailed Godwits for hours wondering why they never move or not
being able to read the letters on a ring which is JUST too far away, no
- it's when you don't get feedback from the ringers! The norm is to get
a reply in a few days but when you have to wait several months it is
annoying and we are currently waiting for feedback for several gulls
and Black-tailed Godwits - no doubt there are good reasons for the
delay but it is still frustrating.
Despite that we have had a good few weeks with the continuing good
numbers of Black-tailed Godwits off Thurstaston and these provide
the bulk of records, plus a handful of gulls, a few small waders and an
Oystercatcher.
Black-tailed Godwits
28 colour-ringed Black-tailed Godwits were logged during December and
January, a good total . In comparison December and January last winter
saw just two! Here is a summary of four of them.
GG-GL,
ringed as an adult in eastern Iceland on May 3rd 2000.
Recorded on Thurstaston Shore three times in January 2017.
This
bird has never been seen outside Iceland or the British Isles. Most
years it spends the post-breeding period on the Humber Estuary, or
other east coast sites whereas Ireland appears to be preferred in
spring. It first appeared on the Dee estuary in January 2010 and became
a regular here up until December 2013. Since then it has only been seen
once anywhere, at Thurstaston in November 2014, before turning up in
January this year. I wonder where it's been?
YL-LX,
ringed as an adult in north-west Iceland on July 14th 2012.
Recorded at Gilroy Scrape and Thurstaston shore four time in January
2017.
The
first record after ringing was in September 2012 at Burton Mere
Wetlands and, apart from a single record back in Iceland and two in
Dublin, has never been recorded away from north-west England/north
Wales.
R8-WO,
ringed as an adult male in northern Iceland on July 15th 2010.
Recorded on Thurstaston Shore 11 times during December 2016 and January
2017.
First record after ringing was at Thurstaston shore in December 2010
and it spent the winter there. July and August 2012 saw it at the
famous Cley Reserve in Norfolk. It spent April 2013 at the Caldy
Wildfowl Collection field (by the Dee estuary) and was seen back in
Iceland that summer. On June 25th 2014 it was on the island of Islay
(Hebrides) implying that it didn't breed that year. But the following
summer it was back in Iceland. It wasn't recorded at all in the winter
of 2015/16 but April 2016 saw it at Leighton Moss. It was recorded
throughout May and June at Siglufjörður in northern Iceland so it was
presumably breeding there. July saw it back in Cley and it was next
seen at Caldy in October before moving north to Marshside, Southport,
in November. It returned to Thurstaston Shore on December 1st 2016.
OL-RZ, (Z
is letter Z on orange ring), ringed as an adult male in south-west
Iceland on July 4th 2012.
Recorded at Thurstaston Shore six times in the second half of January
2017.
This bird is mostly recorded on the Blackwater and Thames Estuaries but
only in late winter/early spring and in August. Until this year's
records at Thurstaston it has never been seen in mid-winter. The only
other record from the Dee estuary was when it was at Gilroy in
November 2014.
Knots
Y flag with letters PAA -
R.
Ringed at Brenna in Porsanger Fjord, northern Norway, on May 26th 2013,
during spring migration.
Recorded at Thurstaston on January 5th 2017.
The only other record was at Southport (seen by Peter Knight, see above
'Tracking Knots' article), on August 14th 2016.
L6GLYY (if
you wish to understand the code for Dutch ringed knot download a PDF
file
here.)
Ringed at De Richel island on the Waddensea, Netherlands, on August
31st 2011.
Recorded on Thurstaston shore on December 28th 2016.
First record after ringing was in Holme, Norfolk, in October 2011. It
was back on the Waddensea in October 2012. January 2013 saw it on
Hoylake shore and it was back again on the Waddensea in September 2016.
Oystercatcher
NG-GflagG.
Ringed as a chick on the north-western tip of Iceland on June 30th 2013
where it was seen feeding a month later.
Recorded on Heswall Shore on January 24th 2017, no other records.
Dunlin
5PL - black
on white ring. Most of our Dunlin records come from the scheme in
Poland where they are ringed near Gdansk and this is one of them. We
are still waiting for details for this bird.
Recorded at Leasowe Bay on December 29th 2016.
Herring Gull
T:334, black on
yellow ring.
Ringed as a chick at Old Slains, Aberdeenshire (north of Aberdeen) on
June 29th 2012, by our friends the Grampian Ringing Group.
Recorded on Hoylake shore on December 13th 2016, no other records.
Black-headed Gull
4HM, black on white
ring.
Ringed in Copenhagen on March 28th 2015.
Recorded at New Brighton on March 5th 2016 and January 22nd 2017.

Smith.
Colour-rings were also reported by Matt Thomas, Steve Hinde, Colin
Schofield, Richard Beckett, Tim Kinch, Elliot Monteith, William Boyce
and John Jakeman.

January Bird News
Brent Geese on West
Kirby Marine Lake, January 4th
© Tanny Robinson
There were two good counts of Brent
Geese during the month with 298 off Hilbre on the 14th (a record high
for the island) and 290 on West Kirby Shore on the 16th. As for last
month small numbers were seen several times on West Kirby Marine Lake
giving some great opportunities for photographs. Two Goosanders were
present there almost every day, I don't remember any other year when we
have
had over-wintering Goosanders on the estuary. Up to two Long-tailed
Ducks and five Scaup were off-shore.
Waxwing in Heswall, January
28th © Frank Burns
There were a few reports of Waxwings through the month but it wasn't
until the 27th that we got a settled flock with up to 29 staying until
the end of the month in Heswall.
Wader numbers haven't been particularly
big this winter but there have been around 3,000 Black-tailed Godwits
at Thurstaston, in the cold wind they were a spectacular sight feeding
close to the beach completely unafraid of passing walkers. Also there
were 370 Bar-tailed Godwits. 18 Purple Sandpipers at New Brighton was
an excellent count on the 14th, it was during strong winds and may well
include birds normally on Hilbre.
On the marshes we have had two male Hen
Harriers and at least two
ringtails. Three Marsh Harriers were seen regularly and there were
reliable reports of numbers in double-figures coming into roost in the
reed beds - remarkable when you think one over-wintering Marsh Harsh
was a rare event just a few years ago. Five Great White Egrets were
present at Burton Mere Wetlands on the 11th and there was a Cattle
Egret there on the 25th. On the same date four Water Pipits were in the
Neston Old Quay area. The Connah's Quay Nature Reserve remains by far
the most important site on the estuary for Twite with at least 60
recorded.

What to expect in February
We should see the first
signs of the
coming spring with birds singing in our woods and gardens, and
woodpeckers drumming away. We could even have our first spring migrant
by the end of the month, usually a Sand Martin, that would be about two
weeks early but it has happened in the past. If it's a good Siskin year
we can start to see them on our garden feeders, always a great sight.
Another
sign of spring will be the return of large flocks of Common Scoters to
Liverpool Bay, pausing here for a few weeks before moving north. With
them could well be a Surf Scoter or two, also out there we can expect
several hundred Great Crested Grebes with, hopefully, a selection of
rarer grebes and sea ducks.
Usually in February we can
expect a high spring tide but the forecast heights are disappointing
this year
and it would take a westerly gale to blow the sea over the marsh at
Parkgate. Nevertheless, the over-wintering Marsh and Hen Harriers will
still be around, as well as a few Short-eared Owls. There will also be
several thousand Pink-footed Geese and may be we will break another
record - it currently stands at 8,900 (Feb 2016) so may be 10,000+!!
There
is still plenty of time for some cold winter weather and we can expect
plenty of waders to still be here, such as Dunlin, Knot and both
Bar-tailed and Black-tailed Godwits. The lower spring tides might well
mean that we get some big wader roosts at Hoylake.
