Little Terns - review of 2017 season.

                                                       Bringing the food home Henry Cook


The Little Tern colony at Gronant had an excellent season in 2017 with a record number of breeding pairs (161) and the second highest fledgling count of 202.  

The increase in breeding pairs, up from 141 in 2016, was unexpected as we had five relative poor years from 2011 to 2015 with fledgling success and in the past that meant a subsequent dip in breeding pairs. For example, looking at the graph you can see two poor fledgling years in 1997 and 1998 resulted in fewer breeding pairs in 2002 whilst a very poor year in 2001 saw less breeding pairs in both 2004 and 2005. The increase in 2017 could be explained by high adult survival in the wintering grounds and on migration, and/or immigration of breeding birds to Gronant from other colonies because of ideal breeding habitat and good feeding. Or maybe the colony is still benefiting from the record breaking season of 2010.

According to the RSPB, Gronant was the largest Little Tern colony, in terms of breeding pairs, in the whole of the British Isles in 2017. But it wasn't the most productive with that accolade going to Kilcoole, just south of Dublin, with 141 pairs producing an estimated 255 successfully fledged young. Kilcoole is only 100 miles due west of Gronant and there appears to be quite a lot of inter-change between the two colonies. We know this because a big effort has been made to colour ring Little Terns over the past two or three years and there were no less than 56 records of birds ringed at Kilcoole at Gronant in 2017, including newly fledged young birds. Colour-ringing is going to revolutionise our understanding of these birds but a couple of fascinating facts have already emerged - a bird ringed as a chick with a black ring in 1991 was recorded at Gronant in 2017 which means it is 26 years old, a world longevity record for Little Tern (previous record was 23.8 years), and the other interesting finding was that several one year old birds, including five ringed at Gronant in 2016, were recorded as well as several two year old birds. Perceived wisdom had it that the first year birds all stayed in their wintering grounds off West Africa through the summer, as did most second year birds - well, it seem perceived wisdom was wrong! 

Although 2017 was undoubtedly a good year it wasn't without it's problems with some exceptional high tides, gales and not least a fox which got into the breeding pens. Quite a lot of eggs were lost to that fox but it was early in the season so the birds could re-lay but if the wardens hadn't stopped it's activities the whole colony could well have been destroyed. This just demonstrates how vitally important wardening is and, as always, a large proportion of these are volunteers. Anybody can volunteer so if you are interested please contact either  the North Wales Little Tern Group by emailing nwlittletern@gmail.com or ring Denbighshire Countryside Services 01745 356197.

This bird was recorded at Southport in April and October 2016, and again there in March 2017. It was at Crosby on 2nd September 2017.
So this bird has only been sighted in Spring and Autumn, where does it spend the winter?

Altcar Knot Catch - March 30th

Oflag(PK) G
Ringed near the Alt Estuary (Altcar) on 30th March 2018, photograph shows the bird just as it has been released after ringing. 
An excellent catch in good weather on Good Friday resulted in 496 Knots with new Orange flags and green rings. As I write this some of these have already been sighted on the Dee estuary by the Hilbre Bird Observatory. Several Bar-tailed Godwits and Grey Plovers were also fitted with Orange flags.

Colour-rings were also recorded by Steve Hinde, Matt Thomas, Les Hall, Steve Williams, Allan Hitchmough, Manu Santa-Cruz, Jason King and Charles Farnell.

March Bird News


                                              Scaup on West Kirby Marine Lake, March 4th Keith Scovell


The 'Beast from the East' was in full swing early in the month with the coldest prolonged spell since December 2010. Cold weather movements included 11 Shoveler at Hilbre (rare here), up to seven Scaup both at Hilbre and West Kirby Marine Lake (probably the same birds), movements of Redwings and Fieldfares were noted and there was a notable influx of Jack Snipes and Woodcocks. Although probably not related to the cold weather over 20 Brent Geese started feeding on West Kirby Marine Lake, these were often close to the Scaup making for an unusual spectacle - they certainly made for some nice photos.

Because of the cold weather everyone thought that the first spring migrants would be severely delayed but the first Wheatear was one of the earliest we've ever had, and, although later than 2017, the other species were not unusually late. Continuing poor weather did mean migration was very slow but that isn't unusual in March, lets hope for some better weather in April!

The table shows the first date each migrant species was seen.

Species 2018 Location 2017 2016
Wheatear 9th March Leasowe
Lighthouse
11th March 23rd March
White Wagtail 14th March Hilbre 4th March 15th March

  17th April 13th April
Swift     19th April 22nd April

  24th April 21st April

Out to sea the first Sandwich Tern of the year was spotted from Hilbre on the 30th and there was a small but steady passage of Little Gulls, max 24 on the 26th. The over-wintering flock of Eiders was present all month, reaching 12 on the 24th.  Common Scoters reached 15,000 on the 7th but didn't seem to stay long, when I saw them they were an awful long way out into Liverpool Bay. A Velvet Scoter was recorded from Leasowe Lighthouse on the 5th.

                     The Merlin in it's favourite tree at Burton Mere Wetlands, March 30th  Mark Woodhead

A female Merlin seemed to take up permanent residence in a tree next to the reception hide at Burton Mere Wetlands, with one or two recorded elsewhere on the estuary. 

Large numbers of Pink-footed Geese were seen including two counts of at least 10,000. Knot numbers were high during the cold spell with up to 30,000 early in the month but most had disappeared by the month-end, either flying east to the Waddensea or north to the Ribble. Avocet numbers were exceptional at Burton Mere Wetlands with reports of a record high number of 122 on the 18th.

Scarcer birds included regular reports of one or two Water Pipits at both Neston Old Quay and Burton Mere Wetlands, up to four Mediterranean Gulls at Burton Mere Wetlands, two reports of over-flying Red Kites, a Black Redstart at Hoylake andreports of Cetti's Warblers at various locations. 

Numbers of Twite at Connah's Quay and Flint haven't been quite as high this last winter but there were at least 60 at the end of the month. These days Great White Egrets are ever present with six the highest count on the 25th, we can but hope that they'll breed here this summer.

What to expect in April

The exciting thing about the spring migration, particularly April, is that we see species we just don't get at any other time of year or are otherwise very scarce. So we'll get White Wagtails, Yellow Wagtails, Ring Ouzels, Whinchats and Redstarts. Some mornings we'll go out and every field will seem to be full of Wheatears and every bush full of Willow Warblers. Grasshopper Warblers will be more likely to be heard rather than seen, but sometimes they sing in full view and surprisingly unbothered by  watching birders.
Take a second look at any large 'gull' overhead - it might just be an Osprey and we always see more in the spring than in the return migration. Out to sea Little Gulls will be flying towards the Sefton Coast from which they fly overland on their way to breed in the Baltic. Last year we had an exceptional passage of Black Terns and they can be either flying along the tide line or over fresh water sites such as Burton Mere Wetlands. On the sea we often get huge flocks of Common Scoters, 30,000+ have been recorded in the recent past.
Whimbrels will be passing through and can be seen anywhere along the coast but Heswall always seems to have more than any other site. I look forward to seeing Black-tailed Godwits in their glorious breeding plumage on their way to Iceland, at this time of year they use fresh water sites such as the lagoons at Connah's Quay Nature Reserve, Burton Mere Wetlands, Caldy Wildfowl Collection and even Gilroy Nature Park which at the time of writing has partially re-filled.  Dunlins will be coming through in their thousands, also in breeding plumage, and there will be good numbers of Avocets at Burton, lets hope they have another good breeding season.
Rarities are almost guaranteed, the last three Aprils have included: Lapland Bunting, Hooded Crow, Glaucous Gull, Iceland Gull, Common Crane, Hoopoe, Dotterel and Alpine Swift.
