WWT & Oxford-Bucks Border Country

Saturday 3rd & Sunday 4th August 2013
Silver-spotted Skipper, Aston Rowant NNR, Oxon
I spent much of the day Saturday at WWT Slimbridge, including going on the morning safari. The Spoonbill was on South Lake, asleep on a post, and was still there a few hours later when I checked after the safari. It awoke for just a couple of fleeting moment. Also on South Lake two female Ruffs, a Green Sandpiper and a Dunlin in addition to the Redshanks, Black-tailed Godwits etc. A Wood Sandpiper was on the Rushy along with four Green Sandpipers, an Oystercatcher and a juvenile Redshank. On the Tack Piece, another Green Sandpiper and two GCP Common Cranes. Fairly quiet bird-wise on the safari, though it was nice to see the 100-acre again after access via Green Lane had been stopped; apparently an announcement about access once again being available is imminent. It was a bit breezy, so not too many dragons either, but we did see a Migrant Hawker, a Brown Hawker, an Emperor, Common Darter and Common Blue Damselfly. Back in the grounds I saw my first Painted Lady of the year, on the Buddleias between Wader Shore and South Lake, and watched female Leaf-cutter Bees (Megachile sp.)collecting nectar and pollen near the centre.

On Sunday, the weather looked favourable to the east, despite the forecast locally. I wanted another butterfly tick and Aston Rowant in the far east of Oxfordshire was in my sights. With Linda for company again, as we progressed along the A40 the weather indeed got clearer, until by the time we hit the Witney bypass it was positively sunny and 21 degrees. Aston Rowant straddles the M40 just west of Stokenchurch and I had unknowingly passed through it before on countless occasions. Silver-spotted Skipper turned out to be by far the most straightforward of my recent butterfly ticks. We opted for the northern, Beacon Hill, half of the reserve. Once onto the steep grassland slope walking along one of several small paths, we were soon almost stepping on the Skippers every few yards. We must have seen getting on for 50, and not only were they very numerous but Chalkhill Blues were also out in force. With scattered clouds and temperatures here around 21 to 22 degrees, both species were obliging. The skippers tend to jump into the air very rapidly when disturbed, almost grasshopper-like, before whirring along quite low, and were quite hard to follow at first. As I got my eye in a bit more I was able to track them to their new resting place, often on a flower after having been surprised from the path. Here they revealed better their intricate under-wing pattern. Other butterflies here included Brown Argus, Ringlet, Large White and Small Skipper. Also Six-spot Burnet, Woodland Grasshopper and Meadow Grasshopper.

We visited West Wycome park afterwards, a National Trust property in neighbouring Buckinghamshire. Beside the architectural and cultural interest, the local Red Kites provided additional entertainment; I counted at least six.

Gran Canaria

Saturday 1st - Saturday 8th October 2016 Hoopoe - Maspalomas A week in the hot sunshine of Gran Canaria at the start of October produced some good birds despite this island not getting much representation in the available range of published bird guides. This isn't surprising since it doesn't hold any populations of the endemic Canary pigeon species which can be found on Tenerife and La Gomera, and Blue Chaffich is much easier to find on Tenerife; next to impossible on Gran Canaria.  Based in Maspalomas at the southern tip of the island, my birding was incidental, or confined to the occasional short solo exploration on foot, in between simply being on holiday. A brackish lagoon, La Charca, stretches behind the beach at Maspalomas, cut off the sea by the beach, and with the dunes along one side. La Charca was always interesting to visit and turned up some good birds. The highlights included (no particular order): Canary Island Chiffchaff - common and vocal virtually ever

Cotswold Orchids and a Garden Hobby

Image
Monday 7th - Tuesday 15th May 2018 Sword-leaved Helleborine, Cephalanthera longifolia Recently I have caught up with Fly Orchids and Sword-leaved Helleborines in the Cotswolds, the latter being a threatened and particularly scarce species in the UK. I have only previously seen Sword-leaved Helleborine, also known as Narrow-leaved Helleborine, in Switzerland, where it more common. Fly Orchid, a close relative of the Bee Orchid, are more widespread but with a localised distribution and not one I have seen before. Both are exquisitely beautiful and very special plants. Fly Orchid, Ophrys insectifera       On 7th I had a Hobby fly over the garden and managed a couple of hurried record shots of this garden tick. A Coal Tit was a surprise garden visitor on 15th as I haven't seen one in the garden since the early spring. Flyover garden Hobby, 7th May Coal Tit, garden, 15th May

Todd's Canada Goose

Image
Saturday 16th January 2010 The Canada Goose showing characteristics of the race Branta canadensis interior , commonly known as Todd's Canada Goose , was in the Rushy Pen at Slimbridge WWT this morning (photos in poor light above and below) , before flying off with other Canada's at 9:40am. This is a very interesting bird, showing several features which together set it apart from its feral counterparts. My observations of the differences are: it is slightly smaller with a more slender neck; shorter bill; narrower white cheek patch; the black on the chin is linked to the black of the neck; at the bottom of the neck at the back, the black joins the brown of the mantle, with no white in between; the pale fringing on the scapulars etc. is much less distinct; the tertials are more contrastingly paler, giving the effect of a pale wing panel; it has a pale eye-ring; and if these features don't help - it has a limp! Other sightings this morning included: Sharpness Docks A female/imm
