Butterfly tour comes up trumps

Today the CFBW Bird Group had its first butterfly and plant walk, led by Steve Gale and Paul Goodman. I came along to lend a hand and it was a great success, with 24 species of butterfly recorded and a specimen of the very rare Cut-leaved Germander being found. The undoubted highlight was the Clouded Yellow at Hither Field, most unexpected. This is the first known report of this species for the patch recording area and even better because it was of the washed-out form helice. Nearby, a Painted Lady showed well and was only the second record of the year, following one yesterday. Three Silver-washed Fritillaries were seen, including one showing well at Fames Rough. Another star species, although not quite as obliging as the rest was a Purple Hairstreak by the pond while strong numbers of Chalkhill Blues were still on the east slopes.

Painted Lady. Only the second sighting at the patch this year

Chalkhill Blue. I took this photo a week or so ago but there were still plenty during the tour

Brown Argus. It's not been a great year for these, though a couple have been on the patch in recent days

Common Blue. Relatively scarce this year but numbers on the tour were optimistic following a recent new emergence

Birds did get a look in, with a single Crossbill flying over that most people managed to see. Steve also heard one calling on the other side of the road that marks the patch boundary, just before the walk began.

Summer ice

Sparrowhawk

A rather casual and relaxed day. I made a change this morning by starting at Banstead Woods. There wasn't much around but it was a nice walk, with a handful of interesting moments to make it worthwhile. Birdwise, a male Sparrowhawk perching nearby in a pine for a couple of minutes allowed a relatively uncommon photo opportunity. In terms of butterflies, I was pleased to see my first Grizzled Skipper, Small Copper (one of my favourites) and Common Blue of the year, plus Holly Blue, Speckled Wood, Brimstone etc.

Small Copper

Later in the day, I paid a brief late afternoon visit to Beddington, where the second calendar-year Iceland Gull showed well. A bit strange seeing it in the heat with flowers, butterflies and young birds all around. The Cetti's Warbler and a Reed Warbler sang close to the hide but didn't show.

Batty

Popped to Epsom Common this afternoon to look for Mandarins (of which I found five drakes and four females) and was amazed to see this bat flying around - guessing at Pipistrelle but haven't researched visual bat ID, ideas?

This drake Mandarin seemed to be dropping water or something from the water on the female's back. Female did several rushes in water, snapping at air (catching insects?) when male following her

 
Also notable, this morning as I drove from Canons Farm to college was an Egyptian Goose flying over the A217 at Banstead Downs, in loose association with another goose that was probably also an Egyptian but I didn't get an detail on this other bird.

Chat hedge

CFBW pulled its fifth (or possibly sixth) Whinchat of the year, and first of the autumn, today. It was in the same hedge in which three of the others stopped off this spring. The very same hedge has been fruitful in terms of other chats, too, with Black Redstart, Common Redstart and multiple Wheatears using it this year. Today's bird was accompanied by a juvenile Stonechat, which was nice.

Purple Hairstreak

Dingy Skipper

On Tuesday I spent a day butterflying (with nets and pots) at CFBW with Ian Magness which proved a success. Our most unusual find was probably a Dingy Skipper; a species which 'sometimes' has a smaller second brood around now and is generally pretty scarce anyway. I particularly enjoyed seeing a male Purple Hairstreak and a Small Copper, both butterfly year ticks (if I kept a butterfly year list) for me. We got a quick look at something which I'm almost certain was a male Chalkhill Blue - it certainly wasn't one of those bright female Common Blues - but it was too quick for the nets and was never seen again. Another highlight was even more of a surprise, and also not a butterfly: a Hummingbird Hawkmoth appeared out of nowhere and started feeding but vanished as hastily as it materialised.

Not every day has a Silver-wash

Silver-washed Fritillary

Over the summer I have been looking for Crossbills at the patch, this has now been achieved. Meanwhile, I have been pursuing a butterfly there: Silver-washed Fritillary. I have been looking for these almost as hard as I have been for Crossbills and today it paid off.

I seldom visit Fames Rough seeing as visiting it involves negotiating a very steep decent; I've lost my footing there a couple of times. That's something you don't want to do when there's a large quantity of big and jagged flint specimens lying around. Also, I don't find climbing back up notable gradients particularly easy. I did it today, though, in the hope of a frit. A Brown Argus raised my hopes but the sun subsequently went in, to my disgruntlement. However, after pausing at the west end for just a couple of minutes I noticed a large orange thing land a few few away - it was indeed a Silver-washed Fritillary! I actually ticked this species off a couple of weeks ago when one circled close around me for ages, but never settled. However, this is the first time that I've acquired satisfactory views of a settled example. Photo attached. Purple Emperor next . . .

Brown Argus

The bird highlight today was very unexpected: just as I was heading home I caught sight of a juvenile Peregrine flushing Woodpigeons from the north end of Broadfield. I also heard a female Tawny Owl calling near Piddly Pond (they're often heard there in the daytime). I pinpointed which tree the sound was coming from and grilled it. Nothing. I give up.

Wildlife treats

Roe Deer

Today, if I had the energy and time, I could have taken my first ever chance to go to the post office and apply for a provisional driving license, seeing as I am now seventeen. Instead, I slowly got ready and went out for a stroll around the patch. I didn't see too much bird-wise, the highlights being a migrant Willow Warbler and a showy juvenile Goldcrest.

Today was memorable for one of the first things I saw when I arrived at Tattenham Meadow. For about ten minutes I watched a doe Roe Deer and her fawn frolick through the now flowering linseed crop. I also managed to get a couple of pics of my favourite butterfly, the Marbled White, which was present in increased numbers at the butterfly hotspot that is the north end of the Legal & General playing field. There were a few small Skippers kicking about too, but only one was obliging enough for me to be able to observe the pattern at the end of its antenna, confirming it as a Small Skipper. Other butterflies present included singles of Comma, Red Admiral and Large Skipper as well as five Small Tortoiseshells and lots of cabbage whites (mainly in Broadfield).

I also finally managed to catch up with a Roesel's Bush Cricket; a species that is rather rare nationally but apparently common in the Sutton area.
