Desert Bound

I'm off birding to Arizona. I'll be posting words and photos again from mid-August.
Thanks for visiting.

Western Scrub-Jay along the River Ayr

I’ve just acquired a copy of a rather nice laminated leaflet describing the wildlife to be found along the River Ayr in southwest Scotland. It is produced by the Outdoor Access Unit at East Ayrshire Council and mentions Catrine Voes, East Ayrshire’s first Local Nature Reserve (shock – ground-breaking stuff!). Now, I’ve been along the River Ayr many times but have yet to observe a Western Scrub-Jay (Aphelocoma californica)! Yes, inside is a photograph of this species from the south-western states of the US. In fact, you can even ascribe it to the Pacific race from California. I’m not sure how this Nearctic exotic managed to find its way into the guide but I’m guessing it was inserted by someone googling for 'Jay'. At the foot of the second page is some text instructing the reader that “the welfare of wildlife and its natural habitat must come first and ensure that you leave the environment untouched”. Obviously this does not apply to Moorfield and it’s extirpated Grayling butterflies…

Scotch Argus at Changue

This weekend I was back in Ayrshire looking for the last two butterfly species of the season to emerge – Purple Hairstreak and Scotch Argus. Kirstie’s Trail through the glen at Changue, near Barr, provided Crossbill, Redpoll, Raven and Buzzard while searching for Scotch Argus. Just five freshly emerged individuals were found. In a week or two there may be hundreds flying in the area. The Fairy Knowe Trail is closed at the moment so we were not able to look for Black Darters along there but Kirstie’s Trail had at least 16 Common Hawkers and two Gold-ringed Dragonflies. Ringlets were fairly abundant along with fewer numbers of Common Blue, Meadow Brown, Green-veined White, Large Skipper, Sexton Beetle, and a Giant Wood Wasp.

Pinbain Burn in the Lendalfoot Hills offered 40+ Graylings and at least one Northern Brown Argus was still flying.

Down in Currarie Glen, conditions were less than ideal for observing Purple Hairstreaks (hot sun and no wind!). Scanning the low, scrubby oaks on the steep hillside of Shallochwreck Burn found no perched hairstreaks in the fairly strong wind. Then, during a brief period of direct sunlight, I watched with the naked eye for some to fly and almost immediately one zipped down hill and landed on the nearest oak, allowing nice views through the optics. A walk down to Currarie Port and around Donald Bowie resulted in 62 Graylings, two Painted Ladies, a single Dark Green Fritillary and a number of Green Tiger Beetles.

Back home on the edge of Kilmarnock, an Oystercatcher flew over the busy Irvine Road to Annandale Golf Course. Hanging from it’s bill was a long worm. This bird was nesting in the area last year as almost the same sight greeted me while driving in the opposite direction, almost a year to the date. Back in the garden, froglets have emerged from the water. For more photographs of these, have a look at my other (wordless) blog: http://luminousnature.blogspot.com/

(No) Graylings at Moorfield

Made a quick visit this evening to the inland Grayling butterfly colony at Moorfield, on the edge of Kilmarnock. This species is almost entirely restricted to the coast in Scotland, so it is quite special to find these butterflies inland. For years, several hundred of these insects emerged each July and August on the post-industrial acid-heath at Moorfield which they shared with Small Heath, Common Blue, orchids, Meadow Pipit, Yellowhammer, Skylark and Grey Partridge to name a few. On Saturday there were no Graylings. In fact there was no anything. This site was destroyed last year by a partnership between East Ayrshire Council (their next move is to destroy enough of Kay Park for a 100 space car park!) and Land Improvement Holdings. They felt it necessary to cap the old bing with a clay covering, thereby obliterating this unique local habitat. This won’t surprise residents of Kilmarnock though – they only have to walk through the soulless, disaster that is the town centre to see that the local authority has little interest in preserving anything, be it natural or man-made. None of the local and national conservation organisations appeared to care, and, worse still, even knew about it despite recording and monitoring at the site. Most people driving by would never realise they were passing a local wildlife treasure. Now they never will.

Arson catastrophe for Thursley Heath

Just heard the devastating news that Thursley Heath/Common NNR has been completely destroyed by the recent fire. I knew it had been bad but not this bad. The heartbreaking thing is that this appears to have resulted from a selfish act of environmental vandalism with a “52-year-old, from Thursley questioned on suspicion of arson after being arrested” (from the BBC). I imagine that it could take at least a decade for the habitat to recover. Whoever is responsible for this should be made to do backbreaking, unpaid conservation work for the rest of their shameful existence (preferably while being birched!).

Thursley Heath Dragonfly Safari

Took the train yesterday from London Waterloo to Milford in Surrey and walked the few miles to Thursley National Nature Reserve with the intention of seeing the Brilliant Emerald dragonfly. This species has a disjunct distribution in the British Isles with populations only in a restricted area of the Scottish Highlands and the south-east of England. The acid heathland of Thursley, together with the bogs pools and surrounding birch, oak, pine woodland and other lakes is well known for its dragonfly diversity and the fine weekend weather made for a fantastic trip. I visited Hammer Pond, Forked Pond, Pudmore Pond, The Moat as well as some of the streams and bog pools in the area and found 21 species! Yet, with all this food source, I didn’t see a single Hobby.

Beautiful Demoiselle Calopteryx virgo
Banded Demoiselle Calopteryx splendens
Emerald Damselfly Lestes sponsa
White-legged Damselfly Platycnemis pennipes
Large Red Damselfly Pyrrhosoma nymphula
Small Red Damselfly Ceriagrion tenellum
Azure Damselfly Coenagrion puella
Common Blue Damselfly Enallagma cyathigerum
Blue-tailed Damselfly Ischnura elegans
Red-eyed Damselfly Erythromma najas
Small Red-eyed Damselfly Erythromma viridulum
Southern Hawker Aeshna cyanea
Brown Hawker Aeshna grandis
Emperor Dragonfly Anax imperator
Downy Emerald Cordulia aena
Brilliant Emerald Somatochlora metallica
Four-spotted Chaser Libellula quadrimaculata
Black-tailed Skimmer Orthetrum cancellatum
Keeled Skimmer Orthetrum coerulescens
Common Darter Sympetrum striolatum
Black Darter Sympetrum danae

The area is pretty rich in other quality wildlife and when not observing dragons I found at least 11 Silver-washed Fritillaries, White Admiral, Silver-studded Blue, Grayling, Dartford Warbler, Woodlark, Tree Pipit, Crossbill and a couple of Green Sandpipers. The heathland is very dry at the moment and the local fire fighters were controlling areas of burning heather. One of the boardwalks, which I guess is meant to cross some wet bog (but was completely charred), was damaged by the fire and I saw none of the Common Lizards which are regularly seen basking here. The high temperatures meant that insects were very active and most would not rest long to be photographed.

Day Trip to Isle of May

Some photos from a couple of hours spent on the seabird island off Anstruther in the Firth of Forth...
