 Little Terns at Gronant

                                Little Terns at Gronant Damian Waters, drumimages.co.uk 

May sees the return of the Little Terns to Gronant having spent the winter off West Africa. Gronant is the only Little Tern colony in Wales and one of the largest and most productive in the UK, to a large extent this is due to the team of wardens and volunteers who protect the colony from predators in all weathers from May to August.  This is important conservation work and as usual we are appealing for volunteers to help us, just an hour or two per week would be a help, more even better. Please ring the Denbighshire Countryside Service (01745 356197) if you want to volunteer or need further details, or just turn up at Gronant during the breeding season to see what is involved - see the Gronant Site Guide for more details both of Gronant itself and the birds to be seen in the area.

         

Little Terns are said to be not particularly site faithful, but there has been little sign of that at Gronant over the years with a steady rise in breeding pairs and relatively little year to year variation in numbers indicating the same birds are returning year after year. What does vary is the number of young successfully fledged  which is typical of any Little Tern colony with weather, height of tides, predation and human disturbance all potentially having a negative effect on breeding success.  2011 was a more difficult season than most with a combination of bad weather and a pair of persistent Kestrels causing a large drop in young fledged compared to the record breaking year of 2010. But the past 10 years have been largely good ones with only two years where numbers fledged were significantly below an average of one per pair whereas for four years numbers fledged per pair were way over one (e.g. 1.9 in 2010). To sustain numbers it has been calculated by the RSPB that the average young fledged per pair has to be 0.66 whereas the long term average at Gronant is actually spot on 1.0, which means we can expect the numbers of pairs to carry on increasing for a long time yet.

Below is an interesting comparison of Little Tern colonies around the UK in 2011 with that at Gronant over the past three years, you can see that the better weather along the East Coast in the summer of 2011 led to good breeding success there, particularly for the colonies along the Cleveland coast. Lets hope that, with the help of the volunteers and wardens, the Little Terns at Gronant can have another record breaking year in 2012.

April Bird News


                             Ring Ouzel near Leasowe Lighthouse, April 11th -   Steve  Round.
With the weather being like it was April was fairly quiet but it certainly had a few highlights including this stunning photo of a male Ring Ouzel, one of six recorded this month. We had to wait until the last day of the month before we had a 'classic' spring migration day when we had over 70 Wheatears, 2 Redstarts, 10 Yellow Wagtails and 7 Whinchats in the Leasowe Lighthouse area - but it was certainly worth the wait! 
First dates of spring migration: 2012, 2011 and 2010
Species 2012 Location (2012) 2011 2010
Sand Martin 28th Feb Leasowe Lighthouse 12th March 18th March
White Wagtail 8th March Leasowe Lighthouse 11th March 12th March
Wheatear 9th March Leasowe Lighthouse 13th March 10th March
Swallow 17th March Red Rocks 20th March 18th March
Willow Warbler 20th March West Kirby 16th March 19th March
Whitethroat  1st April  Hoylake 8th April 7th April
House Martin  4th April  Burton Mere Wetlands 25th March 30th March
Cuckoo  14th April  Leasowe Lighthouse 20th April 10th May
Swift  26th April Leasowe, Burton, West Kirby and Hilbre 17th April 19th April
Other highlights include two rarity records, both of which have question marks over them, as follows:

The first is the 'Ashy-headed Wagtail' at Burton Mere Wetlands on the 18th and 19th. For those that don't realise this is one of several races of the continental from of Yellow Wagtail, most of which have dark heads, unlike the British race which has a yellow head. The 'Ashy-headed' is usually found in Italy. The problem is that there are many intermediates and much variation within the races so it is usually difficult to be certain which race a particular bird is from. Despite this particular bird being identical to 'Ashy-headed' (M flava cinereocapilla)  in my Collins Bird Guide and the experienced birders who actually saw the bird being certain of its ID expert opinion has it that it is not an 'Ashy-headed' but some intermediate form, although their opinion stems from looking at just one 'record shot'. I understand better photos of this bird were taken so it will be interesting to see what the final opinion of the rarity panel is. 


                       "Ashy-headed" Wagtail,  April 18th Paul Brady
 
The second record is of six White Storks. This is a pretty remarkable record, particularly for this side of the country, but they were obviously wild birds. They were probably the ones first seen on April 17th in Worcestershire. There was a report on Bird Guides put out on the 23rd of six in a field by Holywell the previous day (22nd), it must have been these which were subsequently seen and photographed flying over Llandudno on the 23rd by none other than Alan Davies (of the biggest twitch fame - see photos on www.thebiggesttwitch.com), these were flying west (i.e. away from Holywell direction) then flew NNW. Next I received an email late on the 25th from a birder saying that some non-birding friends of his had seen several large heron type birds in a field at Frankby on the 24th, which they subsequently confidently identified as White Storks (they had no knowledge of the possibility of these birds being in the area so no reason to be expecting them to be White Storks). Unfortunately these birds were not present the next day. Just out of interest six turned up in Oxfordshire in late April.

Migration was also taking place out to sea and included good movements  on the 17th with large numbers of auks (including at least 570 Guillemotts) with 100 Gannets and 150 Sandwich Terns off Hilbre the following day. The largest number of Little Gulls recorded were 65 past Hilbre on the 6th.

After disappointing spring tides since April last year we at last had a high tide covering the marsh on the 8th and 9th, the highlight being 8 Short-eared Owls on both dates. Other good birds included five records of single Ospreys overhead and the long staying Great White Egret and Spoonbill.

What to expect in May

May can be good for rarities with 'migration overshoots' - i.e. when birds on migration overshoot their normal breeding area. The last couple of years has brought in Red-Rumped Swallow, Broad-billed Sandpiper, Bluethroat and Nightingale, and we must be well overdue for a Hoopoe - so keep a sharp eye out!

The spring migration will continue well into May and we should see Cuckoos, Hobbies, Yellow Wagtails, Whinchats and Whimbrels among others, and hopefully a Wood Warbler or two. Last May we had exceptional numbers of migrating Dunlin and Ringed Plover along north Wirral shore, and any waders we see are likely to be in full summer plumage with Spotted Redshanks, Bar-tailed Godwits and Grey Plovers looking particularly gorgeous.

Any strong westerly will bring in good numbers of seabirds in to our coast, certainly terns and Gannets but also auks, Manx Shearwaters and may be an Arctic Skua or two.
