Saturday 24th July – Friday 30th July

Intro:

18 species of wader for the week, but just the one that had pulses racing …

Waders:

A number of North Wales birders had to make some rapid changes to plans when news emerged mid-evening on the 27th of a probable Pacific Golden Plover on the Cefni estuary.  A small group assembled on the estuary with the finders – Morgan and Rhys Jones – to view the bird as it moved along the saltmarsh at the base of the cob.  Despite the fading light, good views were had by all and the identification features noted.  The bird stayed for the next few days (27th – 29th at least; weather didn’t help search this morning) allowing a good number to catch up with what will be a 1st for Anglesey and a 2nd for Wales following a bird at Oakenholt Marsh, Flintshire from the 2nd - 4th August 1990.

It was a good week for waders with at least 18 species seen.  In addition to the aforementioned Pacific Golden Plover, there were up to 12 Greenshank at the Alaw estuary (12 on 24th, 8 on 25th), with 2 birds at Traeth Dulas (28th).  A Spotted Redshank was reported at Cemlyn (26th), with 7 Common Redshank at the Alaw estuary (25th).  4 Bar-tailed Godwit were at the Alaw estuary (24th - 25th), with 1 Black-tailed Godwit at the Alaw estuary (24th) and 2 Black-tailed Godwit on Malltraeth cob pool (28th).  Up to 3 Whimbrel were at the Alaw estuary (3 on 24th, 1 on 25th), with single records at Cemlyn (25th), Hen Borth (25th) and Traeth Dulas (26th).  A Ruff was seen at the Alaw estuary (24th), while 5 Knot were at the Alaw estuary (24th) and a further 2 birds at Cemlyn (25th).  Sightings of Sanderling included 2 birds at Rhoscolyn (27th) and 1 at Cemlyn (25th).  39 Turnstones at Cemlyn (25th) was further evidence of the southward bound return passage of birds being very much underway.  Up to 3 Common Sandpiper were at the Alaw estuary (24th), with single records at the Inland Sea (24th), Traeth Dulas (26th, 30th) and Rhoscolyn (27th).  There are still only modest numbers of Dunlin about with 18 seen on the Alaw estuary (24th), 19 at the Inland Sea (24th), 4 at Cemlyn (28th) and 3 at Traeth Dulas (26th).  The Alaw estuary held 152 Curlew (25th) and 158 Oystercatcher (25th).  To round off the 18 species, sightings of Lapwing included a bird at the Cefni estuary (28th), Common Ringed Plover at Cemlyn (29th) and a Common Snipe at RSPB Cors Ddyga (28th).  Any late submissions for Grey Plover, European Golden Plover, Purple Sandpiper, Little Ringed Plover or Green Sandpiper?

Gulls and Terns:

The Elegant Tern was still at Cemlyn throughout the week and has held on whilst the number of Sandwich Terns had fallen to a mere 100 or so.  Will it hold on until the 1st August?  The last report of a Roseate Tern was at Cemlyn (27th).  There were up to 8 Mediterranean Gulls at Beddmanarch Bay (8 on 27th, 5 on 24th) and 4 (including 3 juveniles) at Cemlyn (25th).  One of the 5 birds seen at Beddmanarch Bay (24th) had a yellow darvic ring (AKAT).  The bird had been ringed at Pionierinsel Lühe, Steinkirchen, Stade, Niedersachsen Germany on the 29th May 2021 and had traveled 940 kms before being sighted at Beddmanarch Bay.

Seabirds:

20+ Puffin were seen around Puffin Island (26th), with 3 birds seen off Cemlyn (25th).

Passerines:

A juvenile Cuckoo was seen at Beddmanarch Bay (24th) and a Common Redstart was seen off the minor road between Llanfaelog and Rhosneigr (29th).  A Hooded Crow was at Hen Borth (25th).  There was a first report of a Green Woodpecker for the year, with a bird seen just inland of the Newborough beach car park (28th).

Raptors:

An Osprey was seen over the Inland Sea (24th), with another seen fishing at the Malltraeth Cob pool (28th).  A Hobby flew over Penysarn (26th).

Herons, Egrets and allies:

A Great Egret was at RSPB Cors Ddyga (26th) and up to 10 Little Egret at the Alaw estuary (25th).

Swans, Geese & Ducks:

3 Teal were on the Inland Sea (24th) and 78 Common Scoter flew past Cemlyn (25th).

Divers & Grebes:

No records of note.

 

The forthcoming week 31st July – 6th August?

It is still a good time for rare and scarce terns with a Whiskered Tern at Llyn Maelog (3rd) in 2002, a Caspian Tern at Cemlyn (5th) in 1988 and a White-winged Black Tern at Ynys Feurig, Rhosneigr (6th) in 1977.  A Black Stork was at the Alaw estuary (31st) in 2007, while sea-watching produced 2 records of Cory’s Shearwater – both at South Stack (6th) in 1981 and 1987.

Friday 23 July 2021

Saturday 17th July – Friday 23rd July.

Intro:

Scorching temperatures led to a rather settled week …

Gulls and Terns:

The Elegant Tern continues to delight visitors to Cemlyn and was seen throughout the week (17th-23rd), although it has been spending an increasing amount of time away from the tern colony.  This week has seen a marked reduction in the number of terns at Cemlyn and as noted in last week’s blog, the history of long staying rare terns at Cemlyn suggest that it is likely to depart in the next few days (Bridled Tern, 1988, last day 23rd July; Sooty Tern, 2005, last day 26th July).  Colour ringed Sandwich Terns read at Cemlyn are starting to appear at other North Wales sites (e.g. Rhos Point) so there is still a good chance that the Elegant Tern will be picked up elsewhere once it decides to leave Cemlyn.  It is understood that over 1700 birders have been to Cemlyn to see the Elegant Tern.  Some have donated generously to the North Wales Wildlife Trust who manage the site.  If you didn’t have any cash on the day, or just wish to make a general donation, then please see the North Wales Wildlife Trust appeal page which details their efforts to raise £30,000 towards the cost of wardening in 2020 and 2021.  

At least 1 Roseate Tern – a ringed bird – was still being seen in the early part of the week (18th – 20th).  Just offshore on The Skerries, 1372 Arctic/Common tern fledglings were counted (17th).  8 Mediterranean Gulls were at the Inland Sea (23rd), 1 at the Alaw estuary (23rd) and 1 was seen over a Rhoscolyn garden provided a useful garden tick for the observer (17th).

Waders:

A continuing trickle of waders, but still nothing out of the ordinary.  Sightings of Common Sandpiper included 7 birds at Cemlyn (18th), up to 4 birds at the Alaw estuary (4 on 18th, 2 on 19th, 3 on 23rd) and 1 at Llyn Maelog (19th).  There were 2 Bar-tailed Godwit at the Alaw estuary (19th) and up to 2 Black-tailed Godwit at Cemlyn (2 on 18th, 1 on 17th). 

Up to 13 Greenshank were at the Alaw estuary (13 between 18th-19th, 9 on 23rd), with single birds at the Braint estuary (19th) and at Cemlyn (23rd).  The Alaw estuary (19th) held 17 Redshank (19th), up to 4 Whimbrel (4 on 19th, 3 on 23rd), up to 158 Curlew (158 on 23rd, 114 on 19th), and up to 262 Oystercatcher (262 on 23rd, 186 on 19th).  The number of small waders remains low with few reports.  The highest counts came from the Braint estuary (19th), which had 42 Dunlin, 8 Ringed Plover and 16 Sanderling.  There were 5 Sanderling at Cemlyn (20th).

Seabirds:

An Arctic Skua flew past the Trwyn, Cemlyn (21st).  Up to 37 Puffin were seen off the Trwyn, Cemlyn (37 on 17th, 26 on 18th, 5 on 23rd) with up to 29 adult Puffins seen on the sea at South Stack (29 on 20th, 22 on 23rd).  Up to 3 Black Guillemots were in the bay at Cemlyn (22nd), while in excess of 2000 Manx Shearwaters flew past Amlwch Port during a 1 hour sea-watch (21st).

Passerines:

A juvenile Cuckoo was at Cemlyn (17th), with another not too far away near the marshy field at Pen Carreg (23rd).  The 1st Wheatear of the summer / autumn passage was at South Stack (20th).  A Hooded Crow continues to be reported around South Stack (17th, 21st).

Raptors:

A juvenile Marsh Harrier seen over Tyn Llan fields, Cemlyn (17th) was away from their normal strongholds, while a Red Kites were seen over Cemlyn (21st) and Pentre Berw (23rd).  An Osprey was seen over Beaumaris (22nd).

There was a report of a female / juvenile Montague’s Harrier at Cemlyn (19th).  As a bird that occurs less than 5 times per annum in Wales, the record will need to be considered by the Welsh Bird Rarity Panel.  The observer is encouraged to make contact with Steve Culley, Anglesey County recorder at: SteCul10@aol.com so that a report might be compiled.  Photographs on social media appear to show a bird with too broad a wing structure for Montague’s, so a fully account of the sighting would be most helpful.

Herons, Egrets and allies:

A Great Egret was at RSPB Cors Ddyga (19th) and up to 21 Little Egret at the Alaw estuary (21 on 23rd, 14 on 19th).

Swans, Geese & Ducks:

A Shoveler was at Cemlyn (18th) and 20 Common Scoter were seen to fly past Cemlyn (23rd).

Divers & Grebes:

No records of note.


The forthcoming week 24th July – 30th July?

Still a quiet time of year with just a Pectoral Sandpiper at Llyn Alaw (24th) in 1980, a Rose-coloured Starling at Moelfre (26th) in 1994, a Rose-coloured Starling at Cemaes Bay (29th) in 2020 and a Spotted Crake at Malltraeth (30th) in 2014.

Friday 16 July 2021

Saturday 10th July – Friday 16th July

Intro:

Cemlyn turns up a Phalarope for the 2nd year running …

Waders:

Phalaropes are by no means annual on Anglesey, so Cemlyn has had a bit of a purple patch in turning up a Red-necked Phalarope (21st) in 2020 and now a Grey Phalarope (16th).  Regretably, neither stayed long enough for would be admirers to arrive on site.

One of the notable absences of the spring wader migration was that there weren’t any sightings of Wood Sandpiper, whereas many parts of northern England seemed to get good numbers.  That gap in the year list was filled by one being found at RSPB Cors Ddyga (12th-13th), which also had up to 2 Green Sandpipers (2 on 13th, 1 on 12th).  Up to 6 Common Sandpiper were on the Alaw estuary (6 on 10th, 4 on 11th).

The first returning Red Knot was on the Alaw estuary (11th).  The Alaw estuary also held up to 12 Bar-tailed Godwit (12 on 10th, 4 on 11th, 2 on 14th), while 6 summer plumaged Black-tailed Godwit were at Traeth Dulas (16th).  Up to 15 Greenshank were on the Alaw estuary (15 on 14th, 13 on 10th, 11 on 11th) with just the 1 bird at Traeth Dulas (12th).  Redshank numbers continue to build with 8 Redshank at the Alaw estuary (11th) and 1 at Traeth Dulas (11th,16th).  Up to 3 Whimbrel were on the Alaw estuary (3 on 14th, 2 on 11th, 1 on 10th).  222 Curlew were counted at the Alaw estuary (10th) and 53 birds were counted from Penrhos Coastal Park (15th).  Dunlin numbers remain quite low, with just the 10 birds being reported at the Alaw estuary (10th).  8 Northern Lapwing were on the Alaw estuary (14th).

Gulls and Terns:

The number of Mediterranean Gulls continues to grow with 19 birds at the Inland Sea (10th), 14 at Beddmanarch Bay (14th), 4 birds at Penrhos Coastal Park (15th) and up to 3 birds at Traeth Dulas (3 on 12th, 1 on 16th).  Will we see 100+ birds around the Alaw estuary as happened last year or even surpass last year’s maximum of 136 birds at the Alaw estuary on the 14th August?

The Elegant Tern continues its stay at Cemlyn (10th – 16th) and is now there for its 13th day.  As the young Sandwich Terns start to fledge, birds will start to move away from the security of the island and later disperse more widely.  It is interesting to note that the Bridled Tern in 1988 stayed from the 1st-23rd July and the Sooty Tern in 2005 from the 5th (Rhosneigr) until a last sighting on the 26th July.  How long will the Elegant stay? 

Aside from the Elegant Tern, up to 4 Roseate Terns were noted (10th).  Given a new high in the number of pairs breeding at Rockabill, it has to be hoped that birds might prospect for other potential sites; they would be assured a warm welcome back as breeding birds at Cemlyn.  Reporting of darvic colour ringed Sandwich Terns and locally flagged Common and Arctic Terns continues to turn up some interesting histories.

Seabirds:

Continuing with a ringing theme, 12 European Storm Petrels caught and ringed near Point Lynas (10th-11th) including 2 UK controls – 1 from the Calf of Man and 1 from Bardsey.  A further 2 birds were caught and ringed at Cemlyn (12th).

18 Puffin were seen to fly past Cemlyn (10th) and up to 5 Black Guillemots were in the bay at Cemlyn (5 on 15th, 3 on the 10th).

Passerines:

The Rose-coloured Starling at Moelfre was seen again on overhead wires (10th).  Sightings of single Hooded Crows were reported from South Stack (10th) and from a field south of Amlwch (10th).  22 Chough were seen on fields and at a roost near South Stack (14th).  2 Grey Wagtail that were seen to fly over South Stack (14th) were the observer’s first sighting of this species on passage this summer / autumn.

Raptors:

An Osprey was seen at RSPB Cors Ddyga (12th). 

Herons, Egrets and allies:

2 Great Egret were seen at RSPB Cors Ddyga (12th).

Swans, Geese & Ducks:

Nothing of particular note.

Divers & Grebes:

Nothing of particular note.

 

The forthcoming week 17th July – 23rd  July?

A very quiet time for past records, with just a Corncrake at Tregele (19th) in 2012 and the aforementioned Red-necked Phalarope at Cemlyn (21st) in 2020. 

Friday 9 July 2021

Saturday 3rd July – 9th July

Intro:

16 out of 19 Tern species grace Anglesey ….

Gulls and Terns:

19 species of tern have been accepted on to the British List and 15 of them had been seen previously on Anglesey.  Sunday 4th bumped that number up to 16 when Mark Sutton @keelebirder discovered an orange-billed tern on the main island at Cemlyn.  Whilst it initially proved a little difficult to see amongst the vegetation on the main island, the bird later showed well and the consensus reached was that it was an Elegant Tern – a 1st for Anglesey and a 2nd for Wales after a bird at Black Rock Sands on the 23rd July 2002.  Over subsequent days it was seen displaying to Sandwich Terns and would often fly out to sea from the tern colony for prolonged periods to feed.  Nonetheless, most if not all birders with a little patient waiting managed to see the bird well.  The bird was still present on the 9th.

The 3 species missing for a full house are Least Tern (if only that Dublin bird would take a little jaunt across the Irish Sea), Aleutian Tern (who knows with climatic change) and Cabot’s Tern (still a pity that the 2006 Cemlyn Bird wasn’t able to be assigned confidently to a species).

Aside from the Elegant Tern, Cemlyn also had up to 2 Roseate Terns across the week; the ringed bird that has paired with a Common Tern and an un-ringed bird.  Cemlyn also produced a good haul of colour-ringed terns, including a dozen or so colour-ringed Sandwich Terns.  Most were part of the Lady’s Island Lake, Wexford study with other birds from the Mid-Wales Ringing Group which rings birds caught on autumn passage at the Ynyslas NNR.  Reports of ring readings have shown just how far the Sandwich Terns we enjoy each summer travel, with birds being recorded as far away as the Western Cape, South Africa.  If you are waiting for the Elegant Tern to come back in from a feeding trip, try reading some colour rings.

Turning to gulls, there were up to 7 Mediterranean Gulls at Traeth Dulas (7 on 3rd, 5 on 7th), 7 at the Inland Sea (5th), 1 at Cemlyn (4th) and 1 over Beddmanarch Bay (7th).

Waders:

The return wader passage is very much underway, with a notable increase in a number of species.  There were several reports of Black-tailed Godwits, of the Icelandic race, with 5 birds at Red Wharf Bay (3rd), 1 at Penmon pool (5th), 2 on the Alaw estuary (5th), 2 at Traeth Dulas (8th) and 5 at the Inland Sea (9th).


 Black-tailed Godwit, Traeth Dulas, 7th July.  Photo: J Martin Jones

The Alaw estuary is one of the best places to see Bar-tailed Godwit on the island and up to 11 birds were seen during the week (11 on 6th & 8th, 7 on 5th).  The Alaw estuary also held up to 9 Greenshank (9 on 8th, 6 on 5th), while 1 was on the old brickworks pool, Traeth Dulas (8th).  Up to 4 Whimbrel were at the Alaw estuary (6th, 8th), with 1 at the Inland Sea (5th) and 2 at Traeth Dulas (6th).  Curlew numbers continue to build up with 111 birds at Traeth Dulas (9th) and 90 at the Alaw estuary (8th).  140 Oystercatchers were counted at the Alaw estuary (8th).

There was a noticeable increase in reports of Common Sandpiper with up to 5 birds on the Alaw estuary (5 on 8th, 3 on 5th), 4 birds at Rhoscolyn (7th) and 3 birds at Traeth Dulas (3 on 8th).  There was just the 1 report of a Green Sandpiper, a bird at RSPB Cors Ddyga (4th).  The number of Dunlin is just starting to build with up to 25 birds in the Alaw estuary / Beddmanarch Bay area (25 on 7th, 19 on 6th, 15 on 5th).  It will be interesting to learn what effect high temperatures at northern latitudes may have had on breeding success.  High temperature over parts of NW USA & Canada have been well reported, but perhaps record temperatures in Nordic countries has had less coverage - Lapland recorded its hottest day since 1914.

Herons, Egrets and allies:

Up to 2 Great White Egret were at RSPB Cors Ddyga (2 on 6th, 1 on 4th)

Passerines:

An adult Rose-coloured Starling was seen and photographed at Moelfre (5th) and a Hooded Crow was at RSPB South Stack (7th).  A Rose-ringed Parakeet was seen and photographed at Benllech (7th) and was the 1st report this year of this species.

Swans, Geese & Ducks:

There were several reports of Common Scoter off the coast with 15 offshore from Red Wharf Bay (3rd), 11 flew past Penmon Point (5th), 17 flew past Fedw Fawr (6th) and 48 flew past Cemlyn (9th).  A drake Wigeon, now in eclipse plumage, was still at Valley wetlands RSPB (6th).

Raptors:

A late report of an Eagle Owl last week at Amlwch Port, which presumably is the same bird that has been seen over the past 18 months at Red Wharf Bay and Pentraeth.  Whilst almost certainly of captive origin, it would nonetheless have been a good bird to see.

Seabirds:

It seems that many birds visiting Anglesey for the Elegant Tern also took the opportunity to catch up with the likes of Black Guillemot which locally we perhaps take a little for granted.  Reports of Black Guillemot included up to 10 birds at Holyhead Harbour (8th), 8 birds at Porth Eilian (6th), 7 birds at Fedw Fawr (6th) and 2 birds at Cemlyn (8th).  There were a number of reports of Puffin passing Point Lynas (5 on the 6th) and 3 flew past Cemlyn (9th).  99 Manx Shearwater were counted passing Penmon Point (5th).

Divers & Grebes:

8 Great Crested Grebe were offshore at Red Wharf Bay (3rd).

 

The forthcoming week 10th July – 16th July?

A European Bee-eater was at South Stack (11th) in 1987 and a Woodchat Shrike was at Cemlyn (12th) in 2012.  And perhaps it is not too late to hold out hope for another rare tern, with previous years turning up Britain’s first Lesser-crested Tern at Cymyran Bay (13th) in 1982, a White-winged Black Tern at Llyn Trafwll (16th) in 1977 and a Gull-billed Tern at Point Lynas (16th) in 1978.

Friday 2 July 2021

Saturday 26th June – Friday 2nd July.

Intro:

Return passage of waders gathers momentum …

Waders:

The main highlight of the week was that of returning waders.  Redshank leave the island in late spring with the first birds returning in late June.  7 birds were on the Alaw estuary (26th, 30th, 2nd), with 1 at Traeth Dulas (26th).  The return date matches up well with that of last year, when the first was seen on the Inland Sea (23rd).

Likewise, the first returning Greenshank were seen with 2 on the Alaw estuary (26th), with numbers increasing to 8 (8 on 2nd, 7 on 30th).  Elsewhere, 2 returning Greenshank were at Traeth Dulas (29th).  Again, a good match for the date of last year’s returning birds when the first was at the Alaw estuary (25th).

Both species of Godwit were seen with 10 Bar-tailed Godwit at the mouth of the Alaw estuary (30th) and sightings of Black-tailed Godwit included 1 at the Alaw estuary (26th) and up to 5 birds at RSPB Cors Ddyga (5 on 26th & 1st, 2 on 27th).

Whimbrel and Curlew numbers are starting to build up, with 5 Whimbrel at Treath Cymyran (26th) and up to 2 were at Traeth Dulas (2 on 1st, 1 on 26th, 30th).  33 Curlew were counted on the bend in the river at Traeth Dulas (29th).

There were reports of both Common and Green Sandpiper.  The Alaw estuary had 2 Common Sandpiper (29th), 1 was at Llyn Maelog (1st), 1 was at Holyhead Harbour (2nd) and 1 was on the Alaw estuary (2nd).  A Green Sandpiper was at the Alaw estuary (30th), with another was at RSPB Cors Ddyga (1st).

3 Sanderling were seen on the beach at Rhosneigr (30th), while a Little Ringed Plover (with chicks) was seen again at RSPB Cors Ddyga (27th).

There was a belated, unconfirmed and unattributable, report of a Collared Pratincole at Rhosneigr (25th).

Notable by their absence from reports are both Dunlin and Common Ringed Plover.  The 2nd week of July should see more birds returning. 

Gulls and Terns:

As with returning waders, there was evidence of a movement in gulls.  10 2nd calendar Common Gulls were at Treath Dulas (26th); any early date for that number of birds.  A 2nd calendar year Mediterranean Gull was at Traeth Dulas (26th) and an adult bird was at Cemlyn (26th, 2nd).  At least 1 Roseate Tern – the bird seemingly paired with a Common Tern – was reported on the main island at Cemlyn on most days (26th-2nd), with 1 off the headland at Cemlyn (2nd).

Herons, Egrets and allies:

A Cattle Egret was at RSPB Cors Ddyga (30th-1st), while Great White Egrets were seen at RSPB Cors Ddyga (27th,1st), Cemlyn (29th) and Llyn Llywenan (1st).  There was a further report of a calling Quail at Aberffraw (29th).

Passerines:

A Grasshopper Warbler was still reeling at Cors Efail Newydd, Benllech (27th) and a male Common Cuckoo was at the former Octel site, Amlwch (27th).  A Common Kingfisher was on the old brickworks pool, Traeth Dulas (29th), 40 Swifts were over Llyn Trafwll (30th) and a Hooded Crow was on a ploughed field at Henborth (29th).

Swans, Geese & Ducks:

An unseasonal Pale-bellied Brent Goose was at Traeth Dulas (26th-29th), but was found to be injured and later died.  730 Greylag Geese were moulting at Llyn Trafwll (30th), while 27 Mute Swans were counted at Llyn Maelog (1st).  A female Common Eider was off Beaumaris (26th) and 2 were in the bay at Cemlyn (2nd). 

Raptors:

An Osprey was seen over the Alaw estuary (2nd).

Seabirds:

26 Puffin were seen off the headland at Cemlyn (2nd), albeit distantly.

Divers & Grebes:

No reports of note.

 

The forthcoming week 3rd July – 9th July?

Waders have included a Red-necked Phalarope at Cemlyn (3rd) in 1970 and a Black-winged Pratincole at Mona airfield (4th) in 2001.  Two very good seabirds were a Sooty Tern at Rhosneigr - then Skerries & Cemlyn (5th) and a Cory’s Shearwater at South Stack (6th) in 1991.  Raptors have included a Black Kite at South Stack (6th) and the 2018 Snowy Owl was relocated again at South Stack (7th).  Passerines have included a Turkenstan Shrike at Cemlyn (7th) in 1998, a Common Rosefinch at South Stack (7th) in 2009 and a Rose-coloured Starling at Cemlyn (9th) in 2019.
