Natural History Diary : May 2019
Thursday 16th May
I returned to field east of Barton Fields in Abingdon this afternoon, looking for a reported family of Stonechat, but there was no sign of them. As it was mostly cloudy there were few butterflies about (just two Peacocks and a Small Copper), but there were some Banded Demoiselles, and quite a few Azure and Common Blue Damselflies. I also found what I think is a Variable Damselfly (dark form of the female). I found a female Muslin Moth and a Drinker larva. I saw a Blackcap, and there were two Common Terns over the river. I heard Chiffchaff, Cetti's Warbler and Cuckoo.

Just one Peacock and one Holly Blue at the allotment this morning. The first juvenile Starling of the year appeared in the garden, and there were several visitations by a Holly Blue.
Tuesday 14th May
I had a trip out to Pewsey Downs NNR in Wiltshire today. With a mostly clear blue sky and an agreeable temperature it was almost the perfect day for some butterflying, but the rather brisk easterly wind was a bit annoying. I started out by walking up Knap Hill. There wasn't a great deal to see initially, just some Skylarks. Because of the wind I went straight up to the top, where some gorse bushes provided shelter from the wind. I found some Wall Browns almost immediately. As usual they were quite flighty, not staying settled for long before rising up to battle other males. I counted about eighteen individuals, but there were probably more. I also saw a Green Hairstreak, a Small Copper and a Yellowhammer.
I walked round the west side of Knap Hill, to keep out of the wind. But it wasn't until I got to the south side that I started to see Marsh Fritillaries. Because of the wind they were either down in the grass basking, or fluttering low over the vegetation. I saw about thirty, of which three were females. There were some more Green Hairstreaks here as well.
After lunch I headed the other way towards Walkers Hill. Once I'd got out of the wind Marsh Fritillaries started appearing, and I saw about fifty. Again, most were males. I saw my first Common Blue and Narrow-bordered Five-spot Burnet of the year. As I descended the valley there were lots of butterflies engaged in aerial battles with their own and different species: Small Heath, Brown Argus, Dingy Skippers, Grizzled Skippers, Common Blues and Marsh Fritillaries. While not fighting they were either feeding or basking. In total I'd seen at least 150 butterflies from 12 species, which is pretty good for mid-May.

Monday 13th May
I went to Farmoor this afternoon, mainly to look for dragonflies. The reservoirs resembled their summer state, with just the usual residents present. There were three Common Terns out in the middle of F2. On the way to Pinkhill I saw the first of eight Orange-tips. Blackcap, Chiffchaff, Reed Warbler and Sedge Warbler were singing. Round the back of Pinkhill, where it was more sheltered, I started seeing Banded Demoiselles, and Large Red, Common Blue and Azure Damselflies. Near Shrike Meadow I saw two Whitethroat. There were some Brimstones and Peacocks about too.

Sunday 12th May
I went over to Ivinghoe Beacon to join the Upper Thames Branch field meeting today. The weather was fine and the car park was full. We set off and I found a Duke of Burgundy quite quickly. A couple of Willow Warblers were singing, but I didn't see either of them. I then found what is probably a Sawfly, but I haven't identified it yet. A few Green Hairstreaks were found in various hawthorn bushes as we went down the slope. On the north-facing slope we found more Dukes, Grizzled Skippers, Dingy Skippers and Brown Argus. A Yellowhammer and a Whitethroat were singing.
I then drove down to Pitstone and parked by the church. I spotted a Small Blue as soon as I got into the pit, and I saw about twenty in an hour. The most numerous species was the Dingy Skipper, with at least thirty seen. I also saw a dozen Green Hairstreaks, three Grizzled Skippers, four Small Heath and several teneral Common Blue Damselflies.

Saturday 11th May
This afternoon I walked along the Thames from east of Barton Field in Abingdon through to Orchard Lake. The first species I came across was a Red-headed Cardinal beetle. This was followed by a couple of Banded Demoiselles. Orange-tips, Green-veined Whites, Brimstones and Holly Blues were quite numerous. Chiffchaffs and Blackcaps were singing; I saw one of each. A Hobby flew along the river towards Abingdon. Once off the path I started to see teneral Azure and Common Blue Damselflies. Along the track to the west of Orchard Lake I saw a Garden Warbler and more damselflies. I spotted a dark dragonfly fluttering around a bush, before it landed right in front of me. It turned out to be a pristine female Downy Emerald, which is always a hard species to find, let alone photograph. On Orchard Lake I saw a pair of Canada Geese with three goslings, and a pair of Mute Swans with seven cygnets. I also heard a Cetti's Warbler and a Willow Warbler.

Friday 10th May
A lot of cloud today, but in sunny intervals I saw two Small Whites and a Small Tortoiseshell at the allotment, and a Small White and three Holly Blues in the garden.
Thursday 9th May
A poor day weatherwise, with frequent showers and a cold wind. I visited Farmoor in the late afternoon. There were many Swifts about (walking across the causeway with Swifts zipping past at head height is one of my highlights of the year), and also a good number of House Martins, which are later than usual this year. There were also some Sand Martins, but I only spotted one Swallow. The only other birds of note were two Common Terns, four Dunlin (looking very smart in their breeding plumage) and four Yellow Wagtails (one male and three females). A party of 32 Greylag Geese flew in as I was walking back to the car in the rain.

A female Small White made a brief appearance in the garden at midday today.
Tuesday 7th May
A better day today, with some hazy sunshine, although it was still quite chilly. I went over to Farmoor. A group of about 27 Black Terns were flying low over F2, but as usual they didn't come into camera range. There were sone Arctic and Common Terns as well. There were only a few Swifts and only one Swallow. A bit further on I came across two Sanderling on the causeway. Down at Pinkhill the usual warblers were singing, but it was still too cold for most insects (apart from a male Orange-tip). On the way back across the causeway I heard a Cuckoo, and then I spotted two Whimbrel, which were calling loudly. They flew a wide circuit of F1, then one landed on the wave wall not far from where I was standing. It didn't stay for long, though. Both birds departed to the north.
At home I saw two juvenile House Sparrows and two Holly Blues.

Pretty cold again this morning. As it was sunny I went down to the Elan valley after checking out of the hotel. I found a Treecreeper and a Siskin in the trees on the river bank. Up in the oak woodland I had a close encounter with a Wood Warbler, which was flying around a small clearing, and didn't seem bothered by me taking photos. I also spotted a couple of male Redstarts. The sun had disappeared behind cloud by 11am, so I headed for home.

Saturday 4th May
A pretty chilly morning, but at least it was sunny. I visited the Gilfach reserve north of Rhayader. I saw a pair of Ravens and heard a Cuckoo as I got out of the car. It took some time before a female Redstart showed up. I saw two Dippers near the waterfall. After half an hour in the hide without seeing anything I walked up the hill to the farm. On the way a Garden Warbler was singing in an oak tree. I found a solitary Wood Warbler in the Oak woodland. There was another Garden Warbler near the farm. I walked back on the south side of the river but didn't find much at all. When I got back to the car park an Orange-tip flew across the road. After lunch I walked along the path on the north (south-facing) side of the valley. Here I saw a pair of Stonechats. I was surprised to find a Green Hairstreak in a sheltered spot, followed by a Peacock, a Common Heath and several Green Tiger Beetles. I walked back to the car park along the road. I was looking at a plant in a sheltered hollow off the road when I saw another two Green Hairstreaks and a Small Copper. I then upset a Meadow Pipit by getting too close to its nest, and flushed a pair of Tree Pipits.

Next stop was the Red Kite feeding station at Gigrin Farm. There were small-bird feeders there, which had attracted some Siskins and a Lesser Redpoll. But the main action occurred when food was put out for the Red Kites. Suddenly there were dozens of them (I estimated that there were over 200), all wheeling around in a fairly tight space, and diving down to grab food. There was a leucistic individual among them. A brave Buzzard landed, and found itself ducking out of the way of diving Kites, before grabbing some food and fleeing the field. This is an experience not to be missed!

Today I visited the Elan Valley in Powys. Conditions were not good to begin with, as it rained a bit and was quite cold. There was a bit of sunshine later in the morning. As I walked into the oak woodland I found two of my target species, Pied Flycatcher and Wood Warbler, quite quickly. I then spotted target 3, a Siskin perched at the top of a dead Larch tree. My fourth target species was Redstart, which I also found. Otherwise there were Blackcaps and Willow Warblers singing, a couple of Song Thrushes, a Treecreeper, two Nuthatches, two Goldcrests and a Coal Tit. Overhead I saw a Raven, two of Red Kites and two Buzzards. On the way back to the visitor centre I spotted a female Goosander in the river. After lunch I drove along the shores of the reservoirs, which turned up a few more Pied Flycatchers and Redstarts.

I visited Cors y Llyn NNR in Powys this afternoon. It was cloudy and not very warm. I was surprised to see some Sand Martins near the farm buildings. My target species here was Tree Pipit, and I saw one, but it didn't come into camera range. I also saw Chiffchaff and Willow Warbler.
Wednesday 1st May
A reasonable morning weather-wise. I headed to Farmoor again. The reservoirs were surprisingly devoid of anything of interest, other than a few Common Terns on F2. No hirundines or Swifts! When I got down to Pinkhill I started hearing warblers: Blackcap (4 seen), Chiffchaff, Sedge Warbler (2 seen), Willow Warbler, Cetti's Warbler (1 seen), Reed Warbler, Whitethroat (1 seen), and a Grasshopper Warbler, which I spotted in the reeds at the back of Pinkhill. I found two Banded Demoiselles and three Large Red Damselflies. As I was going back over the causeway I saw two Dunlin, two White Wagtails and heard a Cuckoo.
