Autumn migration increases at Staines Moor

A lot more migrants in evidence at the patch today, including: 2 Greenshank that flew off east from the Colne early morning, 5 Whinchat and 3 Northern Wheatear ranging widely at the north end, 4 Yellow Wagtail around the livestock, 1 Common Snipe along the Colne, 1 1st yr Red Kite N, 1-2 Common Buzzard, 1 House Martin N, 1 Sand Martin NW, 32 Barn Swallow, and 1 Pied Wagtail over (H). Also, 1+ Hobby, 1 Common Whitethroat and 1 Reed Warbler still (Butt's Pond), and c400 Starling, c60 Goldfinch, 3 Grey Heron, 5+ Linnet, 1+ Sparrowhawk, 2+ Kestrel, 9 Meadow Pipit, and 1m and 1f Common Pheasant noted.

1st winter Whinchat - one of five today

Fewer butterflies around now with 3 Small Copper, 3 Small Heath, 1 Large White, and still a fair number of Meadow Browns. Also still several Migrant Hawkers Aeshna mixta about. Photographed some flowering Tasteless Water-pepper Persicaria mitis along one of the iris channels - a fairly scarce plant in Britain (many thanks to Rob Innes for the tip-off).

Migrant meagerness

So yet again autumn migration is well underway everywhere in the northern hemisphere except at Staines Moor. Seemingly every other London site has decent migrants turning up. But at Staines Moor there is hardly a single bird, let alone any migrants! Three hours this morning (26th) logged just 1-2 Garden Warbler, 5 Blackcap (3H), 4 Chiffchaff (3H) and 16+ Barn Swallow. 3 Hobby (not migrants so these don't count) and 2-3 Collared Dove were about the only other birds seen. Spirits are in desperate need of raising.

Butterflies put on a better show with a Clouded Yellow that belted past and refused to settle, 1 tatty Brown Argus, 1 Small Copper, 1 Comma, and 1 Small Tortoiseshell, several Small Heath (second brood?), 1 Large White, several Green-veined Whites, Small Whites and Gatekeepers and lots of Meadow Browns. Also 4 Silver Ys (including 2 actively feeding) and 1 Straw Dot noted.

First garden moth trap session

Finally got around to trying out my new moth trap - a Ranger Capio Actonic - last night (23rd). I originally planned a mothing session at the patch, but I've been ill over the last week so instead had a trial run in the garden with Rachel, Andrew Proudfoot and Peter Alfrey. We ran the trap from 20:30 to 00:15 in fairly good weather - warm, humid, overcast and no wind. Species caught and identified include:

2-3 Red Underwing Catocala nupta
2 Tree-lichen Beauty Cryphia algae
1 Marbled Beauty Cryphia domestica
1 Oak Hook-tip Watsonalla binaria
3 Maiden's Blush Cyclophora punctaria
1 Cypress Pug Eupithecia phoeniceata
4 Double-striped Pug Gymnoscelis rufifasciata
5 Lesser Broad-bordered Yellow Underwing Noctua janthe
1 Large Yellow Underwing Noctua pronuba
1 Straw Underwing Thalpophila matura
5 Willow Beauty Peribatodes rhomboidaria
2 Flame Shoulder Ochropleura plecta
1 Vine's Rustic Hoplodrina ambigua
2 Square-spot Rustic Xestia xanthographa
1 Common Rustic Mesapamea secalis
1 Barred Rivulet Perizoma bifaciata
1 Yellow Shell Camptogramma bilineata
1 Brimstone Moth Opisthograptis luteolata
2 Straw Dot Rivula sericealis
Also, 1 Convolvulus Hawkmoth Agrius convolvuli flew around a few times but avoided the trap and evaded capture!

Micros included:
1 Carcina quercana
1 Mother of Pearl Pleuroptya ruralis
1 Catoptria falsella
1 Diamond-back Moth Plutella xylostella
1 Common Plume Emmelina monodactyla
1 Brown House-moth Hofmannophila pseudospretella

A moth that plays dead!

Never seen a moth play dead before, but that's exactly what this Spectacle Abrostola tripartita moth did a couple of times. Last night as I put it in a container, it flipped over and assumed it's 'I've been swatted' position, then this afternoon while I was getting it out of a container to take some photos it did the same again. I could pick it up, roll it over, and it still didn't flinch! After a while it flipped back over and flew strongly around before coming to rest.

The Spectacle Abrostola tripartita - resting normally one minute...

...playing dead the next...

...then resting normally again.

Here are a few other moths caught and photographed last night at home.

Birdfair 2013

Back from another very successful Birdfair. For Rachel and I it was the seventh year we have organised a stand at the Birdfair for REGUA, but only the second year where we have have not shared a stand. The stand this year was better than ever, down to Rachel's hard work, and as usual attracted a lot of interest. Alan Martin, Rachel and Sue Healey did a wonderful job telling people about REGUA, but a nasty and perfectly timed cold wiped me out for all three days! I lost my voice so was of no real use on the stand on Saturday and Sunday, but it was nice to see many past guests from the lodge, as well as catch up with lots of friends and attend a few talks. Many thanks to everyone who came by the stand to say hello.

One of the highlights for me this year were the several species of caterpillars and moths on display on the Butterfly Conservation stand. Spent a little time watching the ringing demonstration on Sunday, with a juvenile Reed Warbler, Blue Tit and Great Tit all seen processed, and on Friday (16th) a Magpie Moth at our B&B at Stamford, Lincs did its best to take my mind off my streaming nose.
