The consolation prize

Tags

, , , , ,

Do I give the impression that I always find what I go searching for? If I do, then I apologise because I don’t but, rather than letting that get me down, I’ve learnt to appreciate what I find along the way.

Yesterday was one of those days. Three Firecrests had been reported the previous day, in trees around the edge of a local recreation ground; I couldn’t find them. A female Goldeneye had been seen in Cardiff Bay over several days and, though I’d had a fleeting glimpse, I wanted to try for photos; I couldn’t find her. And, though, as you’ve seen, I have already taken photos of the Red-throated diver that’s still feeding in the channel off the Barrage, I was hoping for closer views; it stayed distant.

But there was a consolation prize from my seven-mile walk: the one bird that did pose well for me, allowing a close look at its stunning plumage and some reasonable photos as I watched it drying its wings, this handsome young Cormorant.

Lingering Chiffchaffs

During my most recent circuit of Cardiff Bay, one day last week, I counted at least nine Chiffchaffs, and I’m sure there were probably more.

Most of those Chiffchaffs that intended to migrate should have moved through by now so it’s likely that these remaining birds will linger a while longer, possibly right through the winter, if the weather doesn’t get too cold. It’s lovely to see and hear them still dotting about the trees.

Autumn trees: Hawthorn

Tags

, , , , , , , ,

The Hawthorn (Crataegus monogyna) is not really a tree we notice for its foliage, though its leaves were, apparently, one of the models for the foliage that wreathes the faces of Green Men seen in carvings in churches.

And, according to Richard Mabey’s Flora Britannica, Bread-and-cheese is a vernacular name given to the leaves of the Hawthorn in some places around Britain. He says: ‘This is usually explained as referring to their rudimentary culinary qualities’ but then quotes a correspondent who writes:

We would pick the red berries and green leaves in the autumn. These were known as “bread and cheese” – the leaf the bread, the berry the cheese.

In the autumn, though the leaves of the Hawthorn do, of course, change colour, the hues are mostly yellow and brown, with just the merest hint of red. So it’s the stunning red berries rather than the tree’s leaves that makes the Hawthorn stand out in the autumnal landscape. I’ve never tried eating the berries but Mabey notes that the ‘flesh is a little like overripe avocado pear or, more fancifully, a whey cheese.’ That doesn’t sounds very appetising to me so I think I’ll continue to admire, not to eat them.

Red-throated diver

The identity of this bird, which was first spotted in the sea off Cardiff Bay’s Barrage on Wednesday the 29th, caused a lot of discussion among local birders, which made for an excellent learning experience for me, as I’d only ever seen this species once before. It seems that Black-throated divers (known as Arctic loons in North America) and Red-throated divers (also known as Red-throated loons) can be tricky to tell apart when they’re not in breeding plumage.

The white flank patch on this bird would normally indicate Black-throated but that species, when not in full breeding plumage, almost always has a throat that is mostly black around the back but has a white strip down the front (see this image on Cornell’s All About Birds website). The bills of these species can also be diagnostic; the bill of the Red-throated diver often looks slightly more upswept at the tip, while the Black-throated’s bill looks heavier and straighter; though some birders queried the shape of this bird’s bill, it seems to be within acceptable parameters.

The final decision was that this is a Red-throated diver (Gavia stellata), an adult bird that is still moulting from its stunning breeding plumage into its full winter plumage. Apparently, the white speckling/fringes to the back feathers indicate it’s an adult bird not a juvenile, which would usually have a black back. Cornell’s Macaulay Library has a photo of a similar-looking bird, a much clearer photo that my camera was able to produce at distance and in poor light.

Ghostly fungi

, , ,

‘Tis All Hallows’ Eve and all round the globe
the spirits are rising to roam and to probe,
to spook and to scare,
while you wonder ‘Who’s there?’

With their white colour and partial resemblance to the classic ‘white sheet over the head with holes for eyes’ ghost imitation, these fungi I found on Wednesday in a local park seem particularly appropriate for Halloween. These are White saddle (Helvella crispa), fungi that grow at this time of year in damp soil in deciduous woodland, often alongside paths, which is exactly where I found these.

An Egyptian goose comes to town

Tags

, , , , , , ,

The BTO (British Trust for Ornithology) website reckons that the Egyptian goose (Alopochen aegyptiaca) was introduced to England in the 17th century, presumably to enhance the parks and gardens of the rich with an exotic species – not quite a Peacock, but you get the idea.

Like many other introduced species, these geese have since spread their wings and flown to pastures new or, in this case, more likely lakes, though that colonisation has been quite gradual. The BTO site states:

In 1991 the population was estimated at c.900 individuals, 91% of which were in Norfolk. Since then, the species has colonised the rest of East Anglia, much of London and parts of the Home Counties.

And, from further down the page, by 2013-2017 the UK breeding population size had grown to 1850 pairs.

Sightings of these birds in south Wales have been relatively rare but do seem to have been increasing over the past couple of years. An Egyptian goose – possibly this same bird but there’s no way to be sure – spent several months on a local lake earlier in the year; it was first reported in the WhatsApp group on 23 March (though, of course, it may have been there before that, just not reported by any local birders) and then intermittently through April, May and June. Reports then stopped until ten days ago, when a birder posted that an ‘Egyptian goose set up residency a couple of weeks ago’, which would have been in early October.

As I’d not seen one of these geese since I was last in London six years ago, I decided to go take a look at this local bird. The lake it’s calling home is on the other side of Cardiff and I didn’t fancy the six mile walk through a very industrial area on busy roads so it was a bit of a trek by train and bus to get there … but definitely worth it.

With feathers in multiple shades of brown, with rich rust and bottle green highlights, Egyptian geese are very handsome birds, and this one’s no exception. It looked very settled amongst the other waterfowl, though the Coots were keeping a close eye on it. It was certainly not bothered by the presence of people and, though it turned its nose (beak?) up at my offering of suet pellets, which the other birds were happy to scoff, it happily grabbed the white bread thrown in the water by other visitors, so has presumably lived in a public park setting previously. I was very pleased I’d made the effort to go and see this exotic visitor.

Pretty in Porcelain

Tags

, , , ,

It’s been ages since I’ve seen Porcelain fungus (Oudemansiella mucida) so, though it was a bit sad to see an enormous old Beech tree had lost one of its huge branches, it was a real treat for me to see tiny bulb-shaped fungi emerging all over the wood.

There were hundreds of them, and I’ve just read on the First Nature website that this is due to the fact that ‘Oudemansiella mucida releases a powerful fungicide that deters or even annihilates competitors’, giving Porcelain fungus exclusive access to the nutrients of the fallen Beech.

Porcelain fungus is found exclusively on Beech, usually on dead or dying fallen branches on the ground but sometimes on dead branches high up in the canopy of an old tree.

The mucida in its scientific name refers to the slimy mucus that covers the upper sides of the caps of this fungus. And, though the idea of mucus might give a negative impression, these are stunning fungi, especially when the fruiting bodies are fully open. Their pure white colour and the translucence of their caps is where the common name Porcelain comes from.

Spider: Larinioides sclopetarius

Meet my latest new spider find, Larinioides sclopetarius, also known as the Bridge orbweb spider. So, where did I find it? Why, under a bridge, of course! I must quickly add that I didn’t know what it was when I spotted it.

The railings, that make safe the riverside edge of the footpath that runs under a road bridge over the River Taff, were covered in spiders’ webs so I couldn’t resist having a peek to see what had created them. Most of the makers were hiding, as spiders often do in the daytime, but this one was sitting half in half out of its refuge, so I was able to get a couple of photos to post on social media. I was lucky to get a fairly quick identification from the British Arachnological Society, and the find has been attracting quite a lot of interest from arachnophiles. I’ll have to return to see what else I can find there.

Parasite of Bedellia somnulentella

, , , , , ,

The two Field bindweed leaves I brought home from my coastal walk nearly two weeks ago, on the 14th, are the leaves that just keep on giving. As well as the three moth pupae I found on them – the reason I brought them home in the first place (see my blog Bedellia somnulentella revisited, 20 October), there was another pupa that looked to me to be that of a wasp, probably one that had parasitised another B. somnulentella larva.

That tiny wasp has now hatched. As is often the case with these miniscule creatures, I have no way of determining which exact species of parasitic wasp it is, and I do realise that the whole concept of a wasp larva eating a moth larva from the inside while it’s still alive is a bit gory (perhaps I should’ve posted this on Halloween!), but I find it fascinating, both the process of parasitism and also bringing the occasional things home to see what emerges. The little wasp, a male, has been released to live its best life.

Autumn trees: Norway maple

Tags

, , , ,

Today’s tree is not a British native – it was introduced as an ornamental, has been planted throughout Britain in parks and gardens, and from there has become naturalised, seeded by the wind, birds and critters, making itself at home in hedgerows, on scrubby waste ground and even in woodlands – I can see one from my living room window, growing on the edge of a small slice of regenerating ancient woodland.

The Norway maple (Acer platanoides) is handsome at all times of the year but, for me, the highlight of this tree, as with many maples, is its leaves in autumn. Their vibrant colours range from yellow through to the deepest red, and everything in between, sometimes all in one leaf.
