Thursday December 27

A cloudy mild morning.

 I visited Ipsley Alders where I didn't see a soul, but didn't see any unusual birds either. The best was a Pheasant and a handful of Siskins.

So I went to Arrow Valley Lake where I saw hundreds of people and a good many birders twitching the Black-throated Diver, Among them were Paul Hyde and Des Jennings, so it was very nice to have a catch-up chat with them.

The Black-throated Diver was still showing well.


Goldeneye
Tufted Duck
The Goldeneye has been joined by three Tufted Ducks. I learned, from chatting to various birders, that I had missed some Pochard on a frosty day last winter, and a Pink-footed Goose this week.


The site has never been so popular.

Monday December 24

Sunny with hardly a breeze.

A rare event: Lyn came birding with me. We were of course twitching the Black-throated Diver, and it was late afternoon. The bird couldn't have been more co-operative. It was swimming around off the visitor centre and we were able to view from the opposite bank.

Black-throated Diver
It was diving frequently but on one occasion popped up right in front of us.

A nice by-product of twitches is that you often get to see birders you know. This afternoon, Nick Barlow from Marsh Lane Gravel Pit had been unable to resist making his second ever visit to Arrow Valley Lake. It was good to catch up.

Saturday December 22 - Black-throated Diver

Earlier today I got a text to say there was a Black-throated Diver at Lower Bittell, a very rare bird in a Worcs context. By midday I was wondering whether I might persuade Lyn that we could go to Hillers via Bittell (ten miles in the wrong direction), so I checked t'internet and found the message that it had flown south early afternoon. Well it was only 12.25 when I saw the message, so I thought I had missed it.

Then I thought I could just check Arrow Valley Lake before we went to Hillers. So I arrived to see a familiar shape striding ahead of me, Gavin Peplow. He had obviously had the same idea. I caught up with him as he was scanning. He turned to me and said "its here!"

Neither of us could believe our luck.

Black-throated Diver


Looking into the sun (with Cormorant)

Wing-flapping

Needless to say, the first for the locality.

Much phoning and texting followed, and others soon arrived to enjoy the spectacle.

Just wow.

I didn't take much notice of the other birds on the lake, but did see that the Goldeneye was still present.

One last thing. Back from the shops in the afternoon I found a small Ichneumon wasp sp on its last legs on the draining board in the kitchen. It soon expired and I photographed it in the hope I can find an expert who can identify it.

Tromatoria lineata

I know there are a very great number of possible species and it may require a microscope (which I don't possess). I have retained the specimen. If I do find out what it was, I will update the blog.

This is the update. An expert has identified it as the 44th British record of Tromatoria lineata an obscure ichneumon wasp.

Friday December 14

I decided to take advantage of the brief cold snap hoping that Arrow Valley Lake might be partly frozen. In fact it was ice free, but sunny and cold.

So no new diving ducks, but there was an increase in dabblers. A pair of Teal were new, and there are now 34 Shovelers feeding around the two islands.

Teal
Any fishermen present today would have been dismayed at the sight of 26 Cormorants arriving for their breakfast, while three Grey Herons, a drake Goosander, and the female Goldeneye were no doubt accounting for the smaller fish.

Cormorants in flight, fishermen's fright
A Kingfisher was also present, but although I heard it several times I failed to see it.

Meanwhile back at the ranch, a Fieldfare has started to strip the berries on our cotoneaster, while at least one Redwing has joined the Blackbirds chomping on the apples in the back garden.

Fieldfare

Monday December 10

Sunny intervals and a light north-westerly. Still fairly mild.

I decided on a stroll around Arrow Valley Lake. This produced pretty much the same as always, the only noteworthy bird being a Little Egret, my first since the spring.

Little Egret
Other than that, the Goldeneye was still present, Shoveler numbers have dropped to 11, and there were about eight Siskins and a few Redwings representing winter.

Back home I had a brief view of a male Blackcap on fat balls in the garden. I didn't see any last autumn.

Thursday 6 December 2018

Thursday 6 December

The recent run of mild nights encouraged me to put the trap out, maybe for the last time this year. It was starting to irk me that I hadn't recorded a particular species in the garden. Happily this morning, despite the gloom and rain, a single Winter Moth was sitting on the fence. Job done.

Winter Moth
Not the most spectacular moth, and worryingly similar to a species called Northern Winter Moth which I think would show a white underwing poking out from the skirt of its upper wing. I used to see what I took to be Winter Moths regularly on the front door of the flats Lyn and I lived in in Birmingham 15 years ago (the foyer had a light on all night). But I had never seen one here before......correction, I recorded one in 2009 according to some previous notes I had made.

I also attracted three Light Brown Apple Moths, the first for about two months. This adventive species seems to breed throughout the year, and was not too much of a surprise.

Friday 30 November 2018

Friday November 30

On what the weathermen tell us is the last day of autumn, I found time for a quick circuit of Arrow Valley Lake. The weather was sunny and fairly mild, the breeze gentle and south-westerly.

I am getting used to seeing the same old birds there, and in the main that happened again. The Goldeneye is still present while Shovelers have increased in number to an impressive 28. Not bad considering the only other duck species present is Mallard.

Some of the Shovelers
Just past the bend I did hear a familiar species which was nevertheless the highlight of the visit. A Chiffchaff was audible from the other side of the lake. It always amazes me how the "hweet" of this species can be heard from over 100 metres away.

By the time I had reached the spot it seemed to have shut up. But after a short wait it started up again, and I eventually located it in the lakeside vegetation.

Chiffchaff
It took several minutes of stalking before I got a shot where you could actually make out the bird. Presumably it will try to over-winter here.

My moth trap is out as I am typing this, but with the temperature at eight degrees and falling and rain due before dawn, I may struggle to catch anything. I'll add to this posting when the results are in.

Stop Press: I caught four December Moths, and while I was emptying the trap on the morning of December 1, all the birds in the garden erupted into flight as a male Sparrowhawk flew in and landed on the fence.

December Moth
Sparrowhawk
A Sparrowhawk with red eyes. Hmmm.

Thursday November 22

After a hard overnight frost I resolved to have a walk around Arrow Valley Lake, unfortunately delaying my start until late morning, by which time the bright sunshine and blue sky had been replaced by mist.

In the end I only got about a quarter of the way round before a party of garrulous pensioners was the last straw (I was failing to photograph a Kingfisher at the time) and I resignedly returned to the car park.

In fact the lake did contain quite a lot of waterfowl; 17 Cormorants, 15 Shovelers, the female Goldeneye, seven Coots, numerous Black-headed Gulls and Mallard, and the first Goosander of the autumn.

Goosander
It's interesting that Little Egrets, so regular last year, seem to have vacated the area. It may simply be that I need to get up earlier or go more regularly though.

Passerines were represented by a handful of Siskins and a decent sized tit flock.

Thursday November 15

The recent mild weather has encouraged me to put the moth-trap out for two nights running. Tuesday night was a bit of a disappointment; no moths, one caddis-fly. Last night however was much more productive.

Initially all I could see in the trap was two caddis-flies, but two of the egg boxes turned up three moths. The highlight was my first December Moth, a much more attractive moth than its rather dull name might suggest.

December Moth
It was sharing its egg box with a Brick. This one was worn, but not as badly as the one last week. Another box contained a rather worn Barred Sallow.

Brick
Barred Sallow
Interestingly, the Brick became quite active within ten minutes of the egg box being removed from the trap, just like the last one did. This is not typical noctuid behaviour as most seem to remain fast asleep for hours, so assuming I've correctly identified this tricky species I wonder if this could be an "identification feature".

Some time after I put the trap away I went out to prune the buddleia and noticed I had overlooked a moth clinging to the fence. It was my third Red-green Carpet of the year.

Red-green Carpet
So four moths in one session is the best return since September. The forecast suggests colder weather is on the way, but if mild conditions return it would be tempting to give it another go.

Friday 9 November 2018

Friday November 9

A cloudy day with a moderate south-westerly.

Overnight I gave the moth trap another outing in temperatures which dropped to six degrees. The following morning it contained a Blowfly sp, a Cranefly sp, and a very worn moth.

Brick

The jury is very much out on this one. I wondered about Yellow-line Quaker, while JS said it reminded him of a Sallow, which would be a garden tick. In view of the uncertainty I have posted a photo on the Facebook site which came up with a name for the micro a few days earlier.

If I get any suggestions I will post them.

A walk around Arrow Valley Lake this afternoon was equally disappointing. The Goldeneye and Kestrel were still present along with five Shovelers. Three Redwing flew over. Not much of a return.

PS with a resounding silence from the moth group I emailed a photograph to David Brown (aka the Guru) and he has pointed me to a moth called the Brick. Another tick.

Wednesday 7 November 2018

Wednesday November 7

Its a bit ironic, but I seem to have finally captured a good moth, albeit a micro, without actually deploying the moth trap.

I came home from work yesterday evening and found it resting on the outside of the front bedroom window. I opened the window, extended an arm, and caught it easily enough in a pot. It was a very pale Tortrix moth, and my immediate reaction was pale = worn. Nevertheless I couldn't get it to fit anything, so posted a picture on the Warwickshire Moths Facebook group site I have joined. I was expecting to be either ignored, or be told to stop wasting their time with manky old micros. But no, a Martin Phillip replied in no time at all with the news it wasn't a worn moth, just a very pale one. Moreover he could narrow it down to two species, Acleris kochiella or Acleris logiana.



By now I had released it, but it was still on the window. I measured it as one averages larger than the other. Unfortunately a forewing of 8mm was great for kochiella, but still didn't rule out logiana.

An hour later I thought I should perhaps re-pot it. Sadly (not for the moth) it had gone. So by the time I was being told they would both represent a good record, it was too late.

Also; I saw a Herald on the side of Selfridges in town. My first. Yes I am definitely a novice.

Saturday 3 November 2018

Saturday November 3

Oh Ye of little faith! My pessimistic forecast of no moths was proved wrong this morning when I discovered that my trap contained two moths, and they were both lifers.

The temperature overnight dipped to around 4 degrees, and the egg-boxes were mothless as expected. But on the sides of the trap I noticed first a rather attractive streaky grey moth, and then a less impressive fawn-coloured moth.

At first I assumed the grey one would be a Blair's Shoulder-knot (only because I knew JS had caught one a couple of weeks ago so I'd looked it up), but on closer inspection I concluded it was a Sprawler.

Sprawler
The flight period is given as late October to early December, and apparently it is quite infrequently caught because it mainly flies after midnight.

The fawn one was one I had been half-expecting based on JS's captures. It was a slightly worn Yellow-line Quaker.

Yellow-line Quaker
The books say it flies from September to November, which probably explains why it was a bit tatty. Interestingly the Warwickshire Moth book says it is less plentiful than the Red-line Quaker (which I have yet to see)!

Perhaps its a bit too early to give up on moths.

PS I recently ordered the third edition of Waring and Townsend, which arrived today. As I had suspected the taxonomists have got to work and have changed the Latin names of many moths and have changed the taxonomic order. So I'm going to have to overhaul my gallery and my year list. Oh joy.

Friday 2 November 2018

Friday November 2

As the month changes from October to November, so the emphasis of my recording effort switches from moths to birds. I decided to take a stroll around Arrow Valley Lake for the first time since September.

It was a sunny morning, there had been a loud bonfire night fireworks event overnight and half-term meant numerous families joining the ever present dog-walkers.

Against this backdrop I was astonished to find myself adding two species to my year list, and seeing several other interesting ones to boot.

The big surprise was a female or immature Goldeneye. Initially found sleeping on a raft, it was later seen to be actively feeding. With no regular recording lodged with the WMBC recorder, beyond recent Wildfowl Counts for the WWT, I cannot say how rare they are here. All I can say is that I haven't seen one before.

Goldeneye
Also present in the same arm of the lake, on the next raft in fact, were two female Teal. My last record here was during the beast from the east period last winter.

Teal
The duck tally was completed by four Shovelers, and the usual Mallard. Feeling rather pleased with this turnout I continued my circuit, noting four Cormorants, and single fly-over Skylark and Siskin.

An impressive tit flock included about ten Long-tailed Tits, while a Grey Wagtail flew in and landed in the tiny stream next to the lake. A Kingfisher sat in the foliage on the smaller of the two islands.

I was almost back to my starting point when I noticed a Kestrel perched at the top of a pine tree, seemingly intent on following the progress of some prey item in the close cropped grass below him.

Kestrel
This species has proved to be surprisingly scarce on the patch over the last couple of years. I generally end up hoping to see one perched on the streetlights lining the Coventry Highway, so it was a bonus to see a bird at Arrow Valley Lake for the first time.

One final oddity was a swimming Grey Heron.

Grey Heron
I have witnessed this behaviour before, but probably less than a handful of times in the last forty years of birding. This particular bird took off shortly after I took the photo.

Regarding moths; I have put the trap out tonight, but the forecast cloud cover seems to be late arriving, and I am expecting my first nil return since I started.

Thursday 25 October 2018

Thursday October 25

I fluffed my lines this morning.

The moth trap went out, and I noticed a Light Brown Apple Moth and a geometer sp last night. This morning cloud had rolled in and two Wasps were running along the actinic strip lights at the top of the trap until I turned the light off. The Geometer sp was still present resting on the side of the box. I had three options: a. photograph it in poor light, b. get the book to work out what it was, or c. pot it and photograph it and identify it in better light. Unfortunately I chose c and it escaped before I could get the lid back on the pot. It was some kind of dark carpet moth, but beyond that I cannot say. Stupid!

Anyway inside the trap I found a November Moth ag (which I tried to photograph before attempting to pot it and watching it fly off mid process), and a Shuttle-shaped Dart. That at least was co-operative.

Shuttle-shaped Dart
Also in the trap were three Wasps and a caddis-fly.

Thursday October 18

A sunny morning with very little breeze was good for witnessing overhead movements, a fairly casual look at the sky revealed about 150 Woodpigeons and 70 Starlings heading west, while several Siskins called overhead.

But I was looking at moths. I had put the moth-trap out for the first time since our Cornish holiday, and the first part of last night had suggested it could be a waste of time. Too cold? I had just seen one Light Brown Apple Moth on the trap.

This morning my mood improved by the second as I first found a November Moth ag clinging the the electrical supply pipe, and then discovered no fewer than four Merveille du Jour in and around the trap. This beautiful species is one I had been hoping for, having seen images posted of other people's captures. Neither of these moths appears particularly uncommon, but as we never leave the bathroom window open after September, I have never seen them before.

November Moth ag - Epirrita ag
Merveille du Jour - Dichonia aprilina
The reason November Moths are called November Moth ag is that there are four very similar species which can only be safely identified through dissection and examination of their genitalia. They are November Moth, Light November Moth, Autumnal Moth, and Small Autumnal Moth.

I then noticed a Red-green Carpet (moth) clinging to the brickwork. But only spotted my last "tick" when I showed the egg-box containing one of the Merveille du Jour to Lyn. On turning it over I discovered that in my excitement I had completely overlooked another unfamiliar moth. This turned out to be a Green-brindled Crescent.

Green-brindled Crescent
Again, this seems to be a fairly common moth in the county.

My only other moth was a dowdy Large Yellow Underwing. The light also attracted two species of caddisfly, a Daddy Long-legs sp, and a Harlequin Ladybird.

Thursday 4 October 2018

Thursday October 4

A rather cool night, initially clear, but cloudy when I got up.

Inevitably as the nights get longer the moth lists get shorter. Including a couple of micros I caught on the windows last night my grand total was a paltry 16 moths of 10 species.

At least one of them was new for the year, a Snout. This is a species I have caught in the bathroom during the last few years though.

Snout
It was smaller than the main illustration in Waring, but they have a smaller second generation which this moth fits nicely.

The full list was: one Clepsis consimilana, one Carcina quercana, one Codling Moth, one Light Brown Apple Moth, six Large Yellow Underwings, one Lunar Underwing, two Shuttle-shaped Darts, one Square-spot Rustic, one Snout, and two Lesser Yellow Underwings.

The Light Brown Apple Moth looked different to most I have caught, but I eventually decided it could only be that species.

Light Brown Apple Moth
They are very variable.

Thursday 27 September 2018

Thursday September 27

For the first time in about four weeks I was able to put the moth-trap out following a rise in temperature. The night was still largely cloudless, but I was optimistic, and I was not to be disappointed.

It quickly became apparent that there were more moths about than recently, and this encouraged me to poach a few from the windows rather than just wait until the morning. This did mean that I missed one geometer which I suspected was something like a Spruce Carpet when it was resting on the perspex in the trap, but my attempts to pot it were so ham-fisted that it escaped into the night.

However, it is also true to say that of the 62 moths of 24 species eventually recorded, the seven I detained overnight turned out to involve five new species for the garden year-list (the other captures both being of Common Marbled Carpets). Perhaps I have been a bit too laid back in my approach.

So the first new species (and it was completely new to me) actually flew into our utility room and was caught there. It was a Barred Sallow, a very attractive moth. I released it to take its chances, which meant that in the morning I had to assume that the two Barred Sallows in the trap included the original moth.

Barred Sallow
I next potted what turned out to be another tick, a Brindled Green which was fluttering against the window of the utility room. Like the Barred Sallow my research into the status of the moth locally shows nothing to suggest it was an unusual capture.

Brindled Green
A couple of micro moths were next to be nabbed. The first was a rather non-descript tortrix which remained unidentified until mid-morning when I finally concluded it was a Rhomboid Tortrix. I should say that I haven't had any of the night's records verified by JS yet, and I would say this is in the highest danger of rejection. But they are supposed to fly in September, and I will be disappointed if it gets the boot....Which it did. JS reckons its a male Clepsis consimilana. Oh well, that's what mentors are for.

Clepsis consimilana - male
I actually caught several micro-moths, mostly tortricidae, overnight. This bucked the recent trend which had seen micros all but disappear.

Another micro caught on the window looked extremely non-descript. But come the morning it proved surprisingly easy to identify as a Lesser Wax Moth. Once again this was a lifer.

Lesser Wax Moth
It may be grey and boring, but there was nothing else like it in the book.

Finally, a loo break in the early hours found me potting another pyralid, this time in the bathroom. It reminded me of a Pyrausta aurata (I was half asleep and not wearing my glasses), so I was thrilled to find it was actually even more attractive than I had thought, and was a Gold Triangle.

Gold Triangle
Who says micros are boring? As far as I know, all the micros caught are common moths locally. Just new to me.

So I was well ahead on points by the time I finally got around to checking the trap. And it wasn't long before I was finding more garden year-ticks. The first was a Red-green Carpet. This was a first for the garden, but not for this blog because last year I disturbed and photographed another while I was birding in Winyates Green.

Red-green Carpet
The second was not a first for the garden (I saw one last year), and I recall seeing plenty of them when I went on a moth-trapping session in Coughton Park in 2016. It was a Straw Dot. In my attempt to photograph it on the inner wall of the trap I accidentally disturbed it and ended up pursuing it across the garden where I finally managed some kind of record shot.

Straw Dot
This is a pretty small moth, technically a macro, but not much larger than the Gold Triangle.

The rest of the catch comprised the usual suspects, the bulk being 18 Large Yellow Underwings, and nine Lunar Underwings. Four Marbled Carpets varied in looks as only Common Marbled Carpets can, only one being the easy form with a large panel of orange across the forewing. The others looked like this:

Common Marbled Carpet
Surprising finds were two Carcina quercana, my first for months. They apparently sometimes have a second generation, and the two in the trap looked pretty fresh. A Clepsis consimilana looked worryingly similar to the Rhomboid Tortrix, but seemed slimmer in shape. I have asked JS to verify it.

Clepsis consimilana
Four Light Brown Apple Moths represented a return to form, as did single Celypha lacunana, and Codling Moth. I also photographed what I thought could be a second Codling Moth, but the photo is too bad to show, and does not support the identification. So I don't know what that was.

Many of the noctuids were very worn; a Copper Underwing, a Broad-bordered Yellow Underwing, and a couple of Lesser Yellow Underwings. I also identified a worn Lesser Broad-bordered Yellow Underwing, about a month since the last one. It escaped while I was trying to photograph it, but I think the identification is correct.

Lesser Broad-bordered Yellow Underwing
The glimpses of its underwing certainly show a broad black edge.

Other insects attracted to the light included three Common Wasps, a couple of large Daddy Long-legs', an Ichneumon Wasp of some sort, a small May-fly sp, and two Caddis-fly.

A single Red Admiral was the only butterfly seen, while birds were just the usual garden species.

PS I have adjusted the figures upwards this morning (28/9/18) due to find three more moths in the house last night, all of which must have arrived the night before. Another Lesser Yellow Underwing, a Small Dusty Wave, and a Twenty-plume Moth.

Saturday 22 September 2018

Saturday September 22

A cloudy morning with hardly a breathe of wind, which I must say makes a pleasant change. The last few days and nights have been wild, windy, and wet. This meant constant frustration as I kept considering and rejecting the idea of putting the trap out even though I knew the temperature was due to drop as the week progressed.

Yesterday I even went birding! Admittedly this was just a walk around Arrow Valley Lake which failed to produce anything remotely resembling a storm-blown seabird. The highlights were a pair of Ravens, 20 House Martins, and a trickle of Meadow Pipits heading south.

One reason I was keen to get the trap out is that I have noticed that moths are attracted to the Selfridges building in town and among a lot of Angle Shades and Large Yellow Underwings I found a moth which was new to me. I photographed it on my phone and shared it with JS. He immediately replied with Lunar Underwing which is apparently very common at this time of the year. He expressed surprise I hadn't caught any yet. Now there's a challenge.

So this morning I was delighted that the very first box I turned over contained a Lunar Underwing. In fact I eventually found 11 in the trap plus 15 Large Yellow Underwings, two Lesser Yellow Underwings, a Broad-bordered Yellow Underwing, a Small Blood-vein, a Small Dusty Wave, and a rather small Pale Mottled Willow (the first for a couple of months). I had also trapped a Brimstone Moth on the window during the evening. At least two species of caddis-fly completed the haul.

Lunar Underwing (typical)
Lunar Underwing (pale)
Small Blood-vein
Lesser Yellow Underwing
Pale Mottled Willow
Still no Angle Shades, but I was pleased with the catch as I had half expected single figures.

Finally, my first Siskin of the autumn flew over, while Chiffchaff and Great Spotted Woodpecker called from trees in our around the garden.
