Manx Shearwaters - April to June 2013


                                    Manx Shearwater off New Brighton  Steve Round.


So far 2013 has been an excellent one for Manx Shearwaters. As you can see from the graph below even before the record breaking weekend of June 22nd/23rd this April to June has seen significantly more birds on more days than the previous four years.

The second half of June is often a peak time for Manx Shearwaters as it is at this time that they are incubating eggs and the partner which isn't on the nest typically is away three to five days - ample time for them to reach Liverpool Bay from their breeding colonies. So when the wind went round to WSW and blowing force 6 to 7 on Saturday June 22nd I knew there was a good chance of lots of 'Manxies'. I wasn't disappointed and nearly 1,000 were counted from Hoylake shore, a very high count for Wirral. The next day the wind had increased to force 7 to 8 and, perhaps significantly, the direction had moved to WNW. The birds were streaming past in large numbers all day, the vast majority from east to west, and the total counted was over 5,000 from Hilbre and 3,000 from Hoylake, the count from Hilbre being the highest ever recorded from Hilbre/Wirral. With their fast flight and up and down glides they are an exciting bird to see at any time, but to see so many was just fantastic!

Very large numbers of Manx Shearwaters breed in the Irish Sea with well over 50% of the world's population. Our nearest breeding colony is at Bardsey Island (off the Lleyn Peninsula in North Wales), a rapid increase in breeding birds at the end of the 20th century means there are currently around 12,500 pairs there, with possibly as many as 15,000 pairs. Across the Irish Sea, just south of Belfast Lough, 3,000 pairs breed on the Copeland Islands. But by far the largest colonies are on the Pembrokeshire islands of Skomer and Skokholm, a recent count on Skomer shows that numbers on this island are increasing with an enormous 316,000 pairs, plus there are about 50,000 pairs on Skokholm.

Work by Ronald Lockley in the mid 20th century suggested that, at that time, most birds from Skomer and Skokholm flew south to forage off Brittany and in the Bay of Biscay rather than north into the Irish Sea. However, some fascinating recent research, involving fitting Skomer birds with GPS tracking devices, has found that they must have changed their foraging area as the Irish Sea now appears to be their favourite feeding location. There is something called the Western Irish Sea Front (an area just to the west and south of the Isle of Man where two areas of water meet) which is rich in fish and many of the tracked birds visited here. None of them reached Liverpool Bay but apparently there is sometimes one of these fish rich Sea Fronts here as well and may be that is what is bringing the large numbers here this year. It seems more than likely that we see birds from all four colonies and with breeding birds still increasing we can expect to continue to see good size numbers, but the wind strength and direction no doubt plays a large part in determining exactly how close the huge Irish Sea flocks come to the coast. Interestingly, a year ago on June 22nd 2012, there was a Force 8 gale blowing from WSW, yet only 81 Manx Shearwaters were recorded that day - so there are definitely more around our part of the Irish Sea this year for whatever reason. The bar for 2013 in the graph above is, of course, for this year so far. July is often quite quiet but by August numbers should pick up again. It would be remarkable if that record count in June was exceeded this summer, but you never know!

June Bird News



          Summer plumaged Spotted Redshanks at Burton Mere Wetlands,June 26th Austin Morley.
Gales on the weekend of the 22nd and 23rd certainly brought in large numbers of Manx Shearwaters as described in the above article. Other highlights that weekend were 38 Fulmars off Hoylake, three Arctic Skuas at both  Hoylake and New Brighton and three Great Skuas flying over Little Eye, but only one Storm Petrel seen.  A Black Guillemot was recorded off both Hilbre and Red Rocks early in the month. Numbers of terns and gulls had not yet built up by the end of the month but four Mediterranean Gulls at Heswall on the 24th was a sign of things to come. A rare Roseate Tern was at New Brighton on the 24th. Over 500 Common Scoters off Red Rocks was an unexpected record for June, they were a long way out but I'm not surprised as whenever I'm at Gronant in the summer I have always seen a lot flying past there in flocks of around 50. These will be non-breeding birds, of course, but they are only rarely recorded off north Wirral in the summer.

Talking of terns there was some good news at the Shotton Common Tern colony where about 300 pairs are breeding for the first time since 2008. The Little Terns at Gronant were hard hit by the gales mentioned above, it wasn't so much the strong wind but rather the coincident spring tides pushed in by the gales which flooded some nests. Hopefully they can still have a good breeeding season and I'll let you have the news on this next month. An unexpected visitor to Gronant this month was a Short-eared Owl seen on several days.

There were several Red Kite records, including two over Dungeon Woods, Thurstaston, on the 21st plus several sighting of one near Ness Gardens. A Marsh Harrier was at Burton Mere Wetlands on the 18th.

                              Stonechat near Leasowe Ligthouse, June 8th Jeremy Bradshaw.

Stonechats bred succesfully near Leasowe Lightouse, male photographed above. A Pectoral Sandpiper was recorded on several dates mid-month at Burton Mere Wetlands and there were up to six Spotted Redshanks there, plus a Greenshank at Thurstaston on the 16th. 450 Black-tailed Godwits on Donkey Stand Flash, Parkgate, on Jun 20th was a nice high count of this over-summering flock.

Presumably due to the cold weather earlier on this year there have been fewer Great White Egrets compared with 2012, but one was on Heswall Marsh on the 18th. A Corn Bunting was at Sealand, a good record for this increasingly rare bird.

What to expect in July

I always look forward to July as it sees the return of Sandwich Terns to the estuary in large numbers. They are the first tern species to finish breeding and come here with this year's fledglings for a few weeks before heading south, they fill the estuary with their raucous cries. Common Terns will also be present in good numbers but they don't usually peak until August, whilst the Little Tern breeding season won't be over until early next month.

Gull numbers will increase dramatically and will include a few Mediterranean Gulls looking stunning in their breeding plumage. Out to sea will be Arctic Skuas harrasing all those terns, as well as good numbers of Gannets and, if we get strong winds, many Manx Shearwaters and hopefully some Storm Petrels.

Waders also return this month, specially the fresh water loving species such as Common Sandpiper, Green Sandpiper, Wood Sandpiper, Greenshank and Spotted Redshank. Rare waders which have been recorded this month over the past few years have included a Lesser Yellowlegs and Terek Sandpiper.
