Taking a mini break in Weymouth in the winter was something of a gamble, particularly with the dismal weather we’ve been experiencing this year. I was reasonably lucky except on the Wednesday, when gale force winds saw huge waves rolling in along Weymouth Beach but, as the heaviest rain held off till the afternoon, I managed a quick stomp around Lodmoor, then walked back along the top of the beach to see what the weather had blown in.

First up were several of these egg cases, which have been confirmed as belonging to the Common whelk (Buccinum undatum) though, as the national recorder pointed out on IRecord, the vacant spawn balls float and get blown long distances from where they were laid, so their presence is not evidence of where the Common whelks live.

Next, I spotted this pale-coloured egg case, which I believe is from a catshark, though I’m not sure if it was produced by a Nursehound (Scyliorhinus stellaris) or a Small-spotted catshark (Scyliorhinus canicula). Unfortunately, I didn’t measure the egg case, and it seems the case colour can be variable. The Dorset Wildlife Trust website entry for Nursehound states that ‘Nursehounds [and presumably other catsharks] lay their eggs amongst seaweed. The egg cases have curly tendrils that wrap around the seaweed to prevent the egg case from floating away’.

This last find is proving the most difficult to identify, as there are many similar-looking egg cases – the Shark Trust has an excellent downloadable chart but, once again, I don’t know the exact size of the case. The egg case seems to have been produced by a species of ray and, looking at which rays are found in the waters off the Dorset coast, it may be a Spotted ray egg case (Raja montagui), but that is pure speculation. Suffice to say, I have learned my lesson when it comes to trying to identify beachcombing finds – I will definitely be measuring what I find, and taking more detailed photos as well.

Breaking news!

I’m interrupting the series of blogs on sightings from last week’s mini break in Dorset to bring the best possible news … we have butterflies!!!

Yesterday the temperature in Cardiff reached around 14ºC, warm enough for butterflies to emerge, and, during a walk around Cardiff Bay, I saw my first four Brimstones of the year, two at the wetlands reserve and two more – the two shown here – at the adjacent Hamadryad Park. I find it difficult to express how I feel when I see butterflies in flight; their magic makes my heart sing. If you haven’t seen your first butterflies yet, I hope you do soon!

Wigeon

Like Lapwing, the Wigeon (Anas penelope) is another bird I don’t see very often in my home environment. We get a few occasional Wigeon drop in at Cosmeston Lakes Country Park but they don’t usually remain very long. And, having seen them spending a lot of time grazing in very shallow water and on low grassy areas adjacent to the water at RSPB Lodmoor, I can understand why – Cosmeston simply doesn’t have undisturbed areas where the hundreds of local dogs wouldn’t be able to get to them.

So, as with the Lapwing, it was a real treat to see so many of these handsome birds at Lodmoor. The rich chestnut head and grey upper body of the male Wigeon is a particularly attractive colour combination.

I don’t recall hearing them make any noise (though that may be because their sound was drowned out by the other birds) but the name Wigeon is thought to have been derived from their whistling call. Other vernacular names – whew duck (Northumberland); whewer, whim, whistler (eastern England) – are also imitative of their call, according to Buczacki in Fauna Britannica. Here’s a link to their call on the RSPB website, if you fancy a listen.

Very occasionally small numbers of Lapwing (Vanellus vanellus) are seen alighting briefly in local farm fields or are spotted passing overhead by keen-eyed birders but, generally speaking, Lapwings are a rarity in my part of south Wales. Which is a great shame because they are stunning looking birds, and their evocative call, the Peewit sound that has given them one of their many common names, is wonderful to hear.

So, you can probably imagine my delight when, on the first afternoon of my most recent Dorset trip, I made my first visit to RSPB Lodmoor and immediately saw and heard large numbers of Lapwings. Sporting the largest crest of any British bird and plumage that flashes with a metallic sheen in the sunshine, Lapwings are very handsome birds.

Somewhat surprisingly, it wasn’t the harvesting of their feathers that caused the Lapwing population to crash in previous centuries; according to Fauna Britannica, the declines were caused by people plundering Lapwing nests for their eggs, which were considered a delicacy. The book cites an example where ‘280 dozen lapwing eggs were taken annually in the 1860s’ from just one estate near Thetford.

Lapwings recovered well after this practice was made illegal in the Lapwing Act of 1926 but numbers are once again declining, this time due to changes in agricultural practices; the birds require fallow fields in which to feed during the winter but the majority of farmers now sow their fields twice each year, in spring and again in autumn. According to the British Trust for Ornithology’s publication Into the Red, the Lapwing population in Wales and southern England has declined by 80 per cent since the 1970s meaning the species is now classified as red-listed. It was a privilege to spend time watching these beautiful birds during my four visits to Lodmoor last week.

Scallop shells

In the absence of any new wildflower finds from my break in Dorset, I thought I’d feature seashells this week, in particular the various beautiful Scallop shells I found during a wander along the high tide line. In my ignorance I thought a Scallop was a Scallop, i.e. just one species, but I soon discovered I was very wrong and that I may have seen the shells of at least three different species on Weymouth beach, and that they can be tricky to tell apart.
[** Thanks to a comment from one of my much more knowledgeable followers, I now know that only 3 of the shells shown here (photos 3, 5 and 6) are Scallop species. Obviously, I have a very steep learning curve to climb when it comes to identifying finds at the seaside!**]

I had just thought I would take and share some pretty photos, so I didn’t measure the lengths of the shells, or count their radiating ridges, or examine the size and symmetry of the ‘wings’ on the bottom edge, or even check whether the bowl-shaped shells were attached to other bowl-shaped shells or to flat shells, all features which might have helped with their identification.

From what I’ve read online, the three most likely species of Scallop in this location are Variegated scallop (Chlamys varia), Queen scallop (Aequipecten opercularis), and Great (or King) scallop (Pecten maximus). I’m fairly sure at least two of the shells are the latter species, Great scallop, as they seem to be the only local species that has a bowl-shaped shell attached to a flat shell, and I found a couple of flat shells.

On the Dorset Wildlife Trust website I read one particularly interesting fact about the Variegated scallop that I did not previously know: ‘In common with many other shellfish, the variegated scallop starts life off as a male and changes sex several times during its lifetime.’ Reading about these and the other mollusc shells I noticed but didn’t photograph has definitely piqued my interest in learning more so I’ve just been looking at potential guide books to help with future identification. If you have any personal recommendations, please do share their details in the comments.

I’ve just returned from my first little holiday since last September, a four-night break in Weymouth, a location that’s now a firm favourite of mine. As has become my habit, after checking in to my guest house, I headed east along the seafront to walk off five hours of train travel with a circuit of Lodmoor Nature Reserve. Though the wetlands were more full of water than usual due to all the recent rain and the paths were, as a result, quite muddy, the birdlife was a delight, and, as expected, the species were quite different from what I’d seen in the summer months. Now, there was an abundance of Teal and Shoveler, Lapwing and Wigeon, the latter two not species I see very often and both new additions to my birding year list. The other new species was a real treat and totally unexpected, this gorgeous Avocet (Recurvirostra avosetta). The Avocet is such an elegant bird, crisply clad in classic black and white, with the upwardly curved beak that makes it instantly recognisable. I was entranced and lingered until dusk watching this bird feeding and preening; it was the perfect start to my holiday!

First large spider

As you can perhaps see from the background of my photograph, I spotted this, my first large spider of the year, in the same location as My first moth of the year, described in Wednesday’s blog, on the fencing panels that surround a nearby building site. And I’ve blogged about this species before, when I first found one last April. This is the spider Larinioides cornutus and, though the location might seem a bit odd, as I wrote in that earlier blog, this is a species that prefers living on vegetation in damp places but can also be found on built structures in those areas, hence its presence on these fencing panels alongside a path opposite the vegetation edging the River Taff.

If you’ve been here a while, you’ll know about this beautiful bird from my previous posts but, if you’re new, meet local celebrity Peter Redshank! Celebrity because it’s the only ringed Redshank in the area, Peter because it was ringed as an adult on 22 February 2016 at Peterstone Great Wharf, on the coast of the Bristol Channel just north of Cardiff. Peter has been re-sighted many times each year since 2016 and is now well known to those of us who bird the local area, but it’s always a joy to see him/her (we don’t actually know what gender the bird is) in and around Cardiff Bay. I caught up with Peter and took this portrait one day last week.

My first moth of the year

Those moth-ers who run nightly moth traps have been reporting, on social media and despite the often detrimental weather, that small numbers of moths have begun appearing in their traps during the past couple of weeks. As I don’t trap, I’ve just been keeping an eye out in the places I sometimes see moths, usually on walls near where outside lights are on at night. And, finally, last Thursday, I spotted my first moth of the year, a new species for me, an Early moth (Theria primaria). As you might guess from its name, this is one of the first species to be seen each year, appearing in January and February. Though the UK Moths website says it’s usually found in woodland margins and hedgerows, this one was on the panelling around a building site, though the opposite side of the path is full of trees and scrub.

Three Common sandpipers

During the past few winters those of us who bird Cardiff Bay have been privileged to enjoy regular sightings of two Common sandpipers that are spending the winter foraging those areas around the water’s edge that might provide the tiny creatures they like to eat: insects, spiders, and small crustaceans.

This year the number of wintering Common sandpipers has increased to three.

As most Common sandpipers simply pass through the Cardiff Bay area, moving to their breeding grounds in the spring, and to over-wintering locations further south in the autumn, I like to think that this third bird is the offspring of the original two, introduced to the concept of spending the winter in our area by its parents … but this is pure speculation.
