Little Egret

"Little egret" by Karthik Easvur - Own work. Licensed under CC BY-SA 3.0 via Commons

So here is the 365th post for 2015. I have scratched my head about which species to make the last. All the species I have photos of have been included already and I didn't get out today to find a new one. 
The choice of Little Egret, Egretta garzetta, was made because birds were the first 'wildlife' I began to take notice of and their establishment as a breeding bird in the UK is a relatively recent phenomenon which many consider evidence of climate change. Their big cousin, the Great Egret, is soon to follow in its footsteps.
And it is its feet that are worth noticing. Usually you can't see them as they are wading about in shallow water, but they are bizarrely yellow. Perhaps because on light muddy or sandy shores it disguises them better? Not a strategy shared by other birds with similar feeding habits.

Will I post again tomorrow?

I have decided to stop posting 'daily' but to continue to post when I encounter a new species. It has been a great thing to do over the last twelve months and the aim, to enhance my appreciation of other living things, has been amply met. I have learnt a lot and developed an appetite to learn more. It feels like a proper beginning of something; it's not quite clear what.

Azure Damselflies


A pair of Azure Damselflies, Coenagrion puella, flying in tandem and laying eggs in the pond back in June.

Iris Rust


This Iris foetidissima leaf is infected by the Iris Rust, Puccinia iridis. It is the sort of life one overlooks, even as someone with an expressed interest in natural history. The Rusts are all in the genus Puccinia. They are all obligate parasites of other plants and part of the Fungus kingdom, in the Basidiomycota phylum. There are over 4000 species worldwide, many of the them significant economic pests.

Labyrinth Spider


You have to look carefully but when you do you can just make out the palps of a labyrinth spider, Agelena labyrinthica,  waiting patiently at the end its tunnel.
It is common in the south of the country and is often referred to, inaccurately, as a 'funnel web' spider. 

As usual, there is an impressive amount of information out there on the web, in particular the Spider and Harvestman Recording Scheme.

Neat Feather-moss


Another moss, this time collected on our Boxing Day walk across the Downs from Firle Beacon and back along the old coach road for a warming pint of Harveys in the Ram's snug. It is Neat Feather-moss, Pseudoscleropodium purum, and this is a terrible photo of one of the branches of it taken through the stereomicroscope. Through the hand lens it appears to have succulent overlapping leaves that completely obscure the stem, each with a small recurved mucronate point.
It is common throughout the British Isles.

Dangling Marsh-lover


Yes, another find from Ashdown. I think it's the first hoverfly (Diptera order, Syrphidae family) on the blog. I was looking at the excellent Hoverfly Recording site and according to them 106 hoverfly species have been recorded in my postcode (BN7)! This is Helophilus pendulus, one of the commonest species in the UK. Besides being important pollinators, hoverfly larvae are big aphid-eaters, making them a valuable friend in the garden.

The Streakt Cloudy Hog


Having done the Streaked Golden Hog (aka Small Skipper) I realised I hadn't done this beauty, photographed during my extremely productive sojourn to Ashdown Forest back in July. It is the Large Skipper, Ochlodes sylvanus, the commonest of our eight Skipper family (Hesperiidae) butterflies. It used to be known as The Chequered Hog or Streakt Cloudy Hog - much better names if you ask me, especially the latter.

Roesel's Bush-cricket


Found on the same day as the Mottled Grasshopper, this is a bush-cricket: Roesel's Bush-cricket, Metrioptera roeselii. You can tell a bush-cricket from a grasshopper easily: the latter have long antennae, usually longer than their bodies. Also the females have long, scythe-like ovipositors. Roesel's Bush-cricket has a cream edge to the prothorax. It is also an organism that is spreading in the UK as a result of global warming.

Small Purple-barred


Another find from the Ashdown haul. This is a Small Purple-barred, Phytometra viridaria, whose larva feed on Common and Heath Mildwort which is plentiful around where it was found.

Goldenrod




Having re-discovered my photos taken on the camera (or possibly Ian's camera) there are lots of things from our trip to Ashdown Forest that I didn't use nearer the time. This is one - a rather striking member of the Daisy family, about 70cm tall, with delicate flowers in a tight raceme. It's Goldenrod, Solidago virgaurea and at the time I didn't recognise it. The upper leaves are quite distinctive and differ from the basal rosette of long obovate slightly toothed leaves.
It is found in a range of habitats: dry woodland (where it can be an Ancient Woodland Indicator), grasslands (as here), cliffs and dunes.

Mottled Grasshopper

You will have to zoom in or take my word for it, but this is a Mottled Grasshopper, Myrmeleotettix maculata. You can tell because of the distinctive club-tipped antennae (lacking a white tip). This was take up on the heath in Ashdown Forest back in July.

Great Cormorant

Crossley ID Guide
Plenty of these in the Ouse Valley. They nest colonially on a tiny island in a small lake made by the owner of a local farm. The vegetation has been ruined through shear numbers. The Great Cormorant, Phalacrocorax carbo, is not to be confused (but often is) with the Shag, most notably by Christopher Isherwood in his poem The Common Cormorant.

Creeping Feather-moss

Amblystegium serpens (Creeping Feather Moss)

The problem with mosses is that it's very difficult to show them well in photographs. I was going to take a photo through the microscope but it didn't come out well and wouldn't be that instructive. This is a moss collected growing on the site of a WWI sea-plane hangar at Newhaven. (Well it's not the actual moss but the same species.) This time keying it out was a bit simpler - Creeping Feather-moss, Amblystegium serpens. It's very common and usually found on living or dead wood, but also on soil and stones, the bases of walls and tarmac.

Rook

"Corvus frugilegus -Dartmoor" by Brian Snelson Licensed under CC BY 2.0 via Commons
I've noticed that some Rooks, Corvus frugilegus, are already nest building and possibly even sitting on eggs. It's such a mild winter that this can happen, although a cold snap can be catastrophic for the young if it is prolonged after hatching.


Black-Headed Gull

"Black-headed Gull from the Crossley ID Guide Britain and Ireland" by Richard Crossley - The Crossley ID Guide Britain and Ireland. Licensed under CC BY-SA 3.0 via Commons
There were plenty of these around today down at Newhaven and roosting on the Lewes Brooks RSPB reserve earlier in the week. The 'black' heads of the Black-Headed Gull, Chroicocephalus ridibundus, is in fact chocolate brown and only seen in the breeding season. They have black wing tips which distinguishes them from the similar Mediterranean Gull. The latter also has a heavier bill without the black tip and a truly black hood which extends further down the nape.

Purple Sandpiper

"Calidris maritima" by Andreas Trepte - Own work. Licensed under CC BY-SA 2.5 via Commons
Saw about eight of these little chaps milling about on the lowest parts of the east arm of Newhaven harbour. They are funny to look at with their short legs and dumpy bodies. The slightly down turned beak and beady eye gives them a somewhat shifty appearance. There's something incongruous about their habit of pootling about where the mighty ocean crashes into the land right next to them. The Purple Sandpiper, Calidris maritima, isn't particularly purple even in its breeding plumage. It breeds on Arctic islands and most don't come as far south as Sussex. Their loss from this county is possible with continued global warming, although some regularly overwinter in Portugal.

Pointed Spear-moss

Ciarán Byrne @kiwibyrne  

This grows (abundantly) in my lawn and I've tried a couple of times before to identify it. The last time was probably February, which was probably the last time I'd got the moss book out. It was a eureka moment to finally pin it down but not before I'd arsed about in the acrocarp keys: what an idiot! It's a pleurocarp of course. That's what happens when you don't know what you're doing and you don't start at the beginning.
Anyway, having dissected it under the stereomicroscope and looked at the cellular structure of the leaf under the compound microscope, I could have identified it without either if I'd just followed the key.
It is Pointed Spear-moss, Calliergonella cuspidata. I've nicked the photo from Ciaran Byrne's twitter feed. Ciaran is an amazing ecologist and prolific tweeter. I would urge anyone with Twitter access to follow him.

Floating Sweet-Grass

This is Floating Sweet-Grass, Glyceria fluitans, doing what it says on the tin. It is common in slightly nutrient enriched fresh water ditches where it forms rafts, as seen here.

Watercress

This is Water-cress, Rorippa nasturtium-aquaticum, which is common in the ditches around the reserve. The Latin name gives away its culinary comparison with nasturtium - a peppery flavour. Care should be taken if eating wild Water-cress as it can harbour the cyst stage of liver-fluke, a parasite of sheep and cattle. Only take it from a stream with running water where there are no grazing animals.

Broad-leaved Pondweed


It's been so mild that there is quite a bit of growing going on out there. This is Broad-leaved Pondweed, Potamogeton natans, growing in one of the many ditches. It's only in this ditch that I've come across it, unlike the ubiquitous Lemma minuta. The pondweeds are a tricky group with around twelve species. This is fairly easy to identify because the leaves float and there is often a discoloured joint at the end of the long leaf-stalk.


















Black-Tailed Godwit

By Richard Crossley (Richard Crossley) CC BY-SA 3.0 via Wikimedia Commons
I was doing the WeBS survey down on Lewes Brooks RSPB reserve this morning. There was no wind and it was cold but not crisp. Still few wildfowl, just mallards and a handful of wigeon and teal. But the lapwing were there in numbers, around 200 or so, and when the flock was in the air I noticed another bird flying with them. It looked like an oversized snipe but the trailing feet, clear black terminal band on the tail and white trailing edge of the wings showed it to be a Black-Tailed Godwit, Limosa limosa. It is unusual to see a solitary bird and I think this was the first time I'd seen one on the Brooks. The birds in the UK are of the Icelandic race, L. l. islandica. It calls repetitively in flight.
The similar Bar-Tailed Godwit has a barred tail (no, really) and an equally long beak which has a slight curve upwards. The Black-Tailed Godwit has been Red-Listed since 1996 but the numbers overwintering in Sussex have been increasing over the last 20 years with Pagham and Chichester harbours holding around 3% of the national total.

Red Campion

"Red campion". Licensed under CC BY-SA 3.0 via Commons
Bizarrely I didn't take a picture of Red Campion, Silene dioica, so this is from the amazing resource that is Wikipedia. Red Campion is a bit more widespread than White Campion, growing up to 1000m altitude whereas White Campion is confined to lowland areas, especially those with calcareous soils. It grows at the back of the pond in the garden.

White Campion



Another plant I can't believe didn't get blogged before. The campions, Silene, are a familiar genus. Red Campion is probably best known, but White Campion, Silene latifolia, is also widespread. It can be confused with Bladder Campion and, by the sea, Sea Campion, which both have white flowers. White Campion is usually very hairy. It is also dioecious - having separate male and female plants.

Japanese Knotweed

This is the dreaded Japanese Knotweed, Fallopia japonica, introduced from Japan in 1825 and causing problems ever since. In my native Swansea it was a spectacular problem. Entering the city by train you passed through seemingly endless groves of it. It is listed by the World Conservation Union as one of the world's worst invasive species. In Australia it is actually illegal to have it growing on your property. This was growing on the edge of Amberley Brooks in West Sussex.

Grove snail













This is a common snail which can have be found with a wider variety of patterns. Cepaea nemoralis is known as a Grove snail or Brown-lipped snail and is a terrestrial, pulmonate, gastropod mollusc. Nice.

Cinnamon Bug

This is a hemipteran bug from the Rhopalidae family: the Cinnamon or Black & Red Squash bug, Corizus hyoscyami. It is pretty common but can be confused with other red and black bugs like Firebugs, which are rare here but common on the continent.

Straw Foxglove




This appeared in our front lawn back in June. It looked like a foxglove but not like any foxglove I'd seen before. I did have a cursory look in the books to see if I could find it but failed to find it. Reviewing the year's photos I came across it again and this time I've found it. It's Straw Foxglove, Digitalis lutea, an introduced species that has naturalised in the south of the country. It's actually rather rare, as this BSBI map indicates, and there hasn't been a record in Sussex since 2010 when it was noted in Brighton.
The flowers are distinctly those of the Figwort family, Scrophulariaceae. The most striking feature is the extremely hairy corolla.

Common Spotted-Orchid




















Here's another common plant: the Common Spotted-Orchid, Dactylorhiza fuchsii. It has transversely elongated spots on its leaves (hence the name) which help distinguish it from Early Purple-Orchid, which has longitudinally elongated spots, and Heath Spotted-Orchid, which has circular spots. These plants were found on the same day, not far from each other,  illustrating the range of colours and patterns found within this species.


Burnet Companion

This day-flying moth was spotted enjoying the nectar from Horseshoe vetch up on the Downs. It's Burnet Companion, Euclidia glyphica, and is reasonably common down south, especially on chalk grassland.

Woodbine

I didn't realise that Woodbine was a synonym for Common Honeysucke, Lonicera periclymenum. I was also suprised I hadn't already blogged this as it's a lovely and common plant. There turn out to be lots of photos of plants taken in the middle of the year when there was an abundance in flower which I didn't have 'room' for at the time. 
Honeysuckle is famous for its scent, which is strongest at night to attract the long-tongued moths that pollinate it. They can detect it from quarter of a mile away (how is that known?).

Heath Spotted-Orchid




















Although similar to the commoner Common Spotted-Orchid, this is Heath Spotted-Orchid, Dactylorhiza maculata, growing in fairly boggy ground in a ghyll in Ashdown Forest just next to the Lesser Skullcap posted recently. All orchids seem exciting. There's something exotic about them despite their abundance.

Giant Bellflower




















Giant Bellflower is not common down south. This is the white form, Campanula latifolia var alba, which is often grown in gardens. Indeed this is likely to have escaped from a garden. It was found back in early July on the Downs near Lewes.

Lesser Skullcap




















This is Lesser Skullcap, Scutellaria minor. It is not as common as Skullcap, which has toothed leaves and curved blue-violet flowers. 
I came across this by a stream when I did my National Plant Monitoring Scheme surveys in July. It took me a while to identify!

Common Chameleon

Common Chameleon, Chamaeleo chamaeleon, (and to a far lesser degree the African Chameleon, Chamaeleo africanus) is found in many Mediterranean countries. This one was picked up (literally) in Morocco where they are associated with the devil and a great deal of folklore

Butcher's Broom

I came across this growing at the base of a hedge bordering a driveway to some old cottages and the church at Compton Beauchamp. It's Butcher's Broom or Ruscus aculeatus. It is a peculiar plant. The 'leaves' are actually flattened modified stems (cladodes) in the middle of which the small whitish flowers appear. The red fruit look almost artificial in colour.
In many areas of the country it is an ancient woodland indicator. It used to be part of the Lily family but this has now been re-named the Asparagaceae family.

Red Kite

"Red Kite - Gigrin Farm" by Tim Felce (Airwolfhound) - Red Kite - Gigrin Farm. Licensed under CC BY-SA 2.0 via Commons
I had to finish off my trio of birds from my recent trip to the Wessex Downs with the Red Kite, Milvus milvus. This magnificent bird is recolonising the country after near extinction save for a small area of central Wales centred around Gigrin Farm where this bird was photographed (and no doubt fed).
They remind me a little of Marsh Harriers with their striking wing markings and gliding habit of tail-twisting. In medieval times they kept the streets clean of carrion, helping to reduce the risk of water pollution and other sequelae of putrefaction.

Yellowhammer

"Emberiza citrinella -New Zealand" by Alan Vernon - originally posted to Flickr as Yellowhammer (Emberiza citrinella) in New Zealand, North Island. Licensed under CC BY 2.0 via Commons
A rather grey and occasionally drizzly walk today. The wildlife highlights were the prodigious numbers of spindle trees in the hedgerows (almost as many as the hawthorns) and the flock of yellowhammers, Umberiza citronella.
There were around twenty birds with half as many Chaffinch and a pair of Bullfinch. Certainly the largest flock I've seen to date. The intensity of the yellow male plumage is shocking when you first see it, making you think that this must be an escaped exotic such as a Canary.
They have a distinctive song which is usually rendered in the books as "a little bit of bread and chee-eese."

Fieldfare

"Turdus pilaris" by Arnstein Rønning - Own work. Licensed under CC BY-SA 3.0 via Commons
I saw my first fieldfare, Turdus pilaris, of the season today whilst walking along the Ridgeway above the white horse at Uffington. In fact I saw about 300, more than I've ever seen before in a flock. They made an impressive sight, outnumbering the starlings nearby.
