A lucky pair of Magpies brings me Little

I headed out with renewed optimism this morning that the time I'm putting in will eventually get it's rewards.  I walked on down the Bill.  But, after taking in Barleycrates Lane, Suckthumb Quarry, Avalanche Road Hump, Reap Lane, and the Admiralty Hedge, and only seeing a few Willow Warbler, 3 Wheatear, and a juvenile Sparrowhawk, my hopes started to fade.  My mood wasn't helped when I dropped my phone on the pavement, smashing the screen into a thousand pieces.  Rather incredibly, it still works fine, even the touchscreen!  Viewing images is now a little harder however.  The only amusement I could get from this walk, was a Horse farting.  I am fairly mature, honest.

I popped into the Obs, only to find that yet again, the guys sitting around there had seen much more than me!  I will try and resist taking this easy option as much as possible.  I'm a doer.

I was able though to look at the moths, and there were some beauties.  The only macro lifer was the top-notch immigrant, Bordered Straw, and a nice fresh one too.

 
Also among the highlights were one of two Jersey Tiger.
 
 
Only my second ever Small Wainscot (the first being last week at Alners).
 
 
And this quite rare micro, Aristotelia brizella, a Thrift-feeder.  Sorry for poor pic.




On the way back home, I took a route along the East Cliffs.  Here, the migrant monotony was at least broken a little by a Yellow Wagtail which flew over and seemed to come down in the Crown Estate Field.  I later heard it again, flying back north towards Southwell.  I also came across another 3 Wheatear here.

 
This area in the East Cliff quarries is very sheltered from the current westerlies, so butterflies were in profusion.  I was lucky enough to see two more Clouded Yellow, though sadly (and rather typically) they wouldn't land for pictures.  The other entertainment here was provided by a juvenile Rock Pipit attempting to subdue a Grasshopper.  The bird kept dropping it, and the Grasshopper still had hops in it!  It did eventually go down the hatch.
 
The main highlight for me though was spotting my first ever juvenile Little Owl, which was brought to my attention by the actions of a pair of Magpie.

 
Having had enough of the Magpies attention, he took cover.

 
A bit of a stand-off.



But they did eventually go away, leaving the little guy to sunbathe once again.


Isn't it about time we got a Melodious Warbler?

Black (neck) and White (death)

The last few days have been rather uneventful.  All I can really report on the bird front is the occasional Balearic Shearwater still off the Bill, plus a Whimbrel past yesterday, and a trickle of hirundines and Swifts moving south overhead.  Some of these are also starting to gather on fences before the big push.

 
 
The weedy field right next to these Swallows (in the Top Fields towards Southwell), was alive with House Sparrows, Meadow Pipits, Linnets, Greenfinches, and Goldfinches.  A delightfully large proportion of which (as well as the Swallows) were juveniles.  This area will certainly repay further scrutinisation (made up word?!) come the autumn proper.
 
Really, the last few days have been about the butterflies.  A couple of days ago, I nipped out to Blacknor Point to do my Big Butterfly Count (read about this important survey here: http://www.bigbutterflycount.org/ ).  A 15 minute walk later and I was so mesmerised with the numbers I'd seen, I had to estimate!  The highlights were loads of Chalkhill Blue (estimate: 25), at least 5 male Oak Eggar moths in flight, and an egg-laying Grayling on the precarious cliff-edge!
 
 
Earlier on at the Bill, I had also seen this fresh second-generation Wall.
 
 
 
Today, I decided to take an off-island excursion to the Butterfly Conservation reserve of Alners Gorse.  The place is very much in the middle of nowhere, but it's a little gem.  The open areas are carpeted with plants I would consider scarce, such as Dyer's Greenweed, Sneezewort, Devil's-bit Scabious, Saw-wort, and Burnet-saxifrage.  Unsurprisingly, the Lepidoptera is also excellent. 
 
 
 
They were having an open day with walks and moth trap opening.  Well, that was the first port of call for me!
 
I helped out with emptying the 5 traps, which took 3 hours! Heaven!  We didn't total them up at the time, but I'm expecting over 100 species, on what was not the best of nights weather-wise.  The only macros that were lifers for me, were a couple of Blackneck, and a presumed Small Wainscot.
 

 
Also among the highlights were at least 15 Double Kidney.


The stunning Blood-vein.


And a Mocha, which is pretty scarce, though I have seen several before in Surrey.

 
While I was busy up to my neck in July Highflyers and Agriphila selasella, one of the butterfly walks went off to look for the reserves Hairstreaks.  Four of the UKs five species occur here, with all but one (Green) flying now.  The weather all day was pretty hopeless quite frankly, with strong winds and barely a hint of sunshine.  Despite this, the first group came back with sightings of all the Hairstreaks, including one bloke who had managed to photograph all three together! Amazing!
 
 
After I'd finished with the traps, I went off on my own into the best area for the Hairstreaks.  I soon found a lovely spot, with some Bramble flowers blooming, that had several Silver-washed Fritillaries, plus a single Purple Hairstreak, though sadly, it was completely uncooperative when it came to photos.
 
 
I also found this pretty micro, Ancylis badiana.
 

I then came across a couple peering up into a bush. They said they had a Hairstreak, though they weren't sure which one.  It took some finding, but I eventually found the rascal, and ID'd it as a White-letter Hairstreak.  I sat and watched it for ages, but sadly, apart from having a wander up and down the twig, it would not fly into a more viewable position.  The drizzle by this point didn't help!

Once I got back, they were ready to do the second guided walk, and they ended up doing a very similar route to the one I'd just done, without the Hairstreaks!  The group did eventually see a Purple, though no Browns sadly, which was the one I was most hoping for, having only had a very poor view of one before at Pulborough Brooks.  We did find some interesting Bush-crickets, including an immature female Long-winged Conehead and Dark Bush-cricket.

The other interesting observation we made was first a Ringlet...


...then a Marbled White, both in the grasp of the crab spider Misumena vatia, sometimes known as White Death!

 
 

Meanwhile, back on Portland, I'm hopeful that the continuing strong-ish south-westerlies will bring one of the more unusual Shearwaters our way tomorrow.  Just one will do!
