British lichens, Cardiff Bay, Cardiff Bay Barrage, lichens on concrete

Cardiff Bay Barrage is a monument to concrete, 135,000 square metres of concrete – in fact, it received an award from The Concrete Society soon after it was completed. And lichens love having so much concrete to colonise!

According to that same Concrete Society, ‘As the concrete ages, the surface alkalinity is reduced by carbonation and the action of rainfall, thus providing a more suitable environment for biological growth.’ And, as lichens are sensitive to air pollution, the almost constant blasting of fresh air aids their lush growth, as you can see from these photos, taken during one of last week’s exercise walks.

341/366 Blooming on the Barrage

#winter10, British wildflowers, Cardiff Bay, Cardiff Bay Barrage, winter wildflowers

During Tuesday’s walk across the Barrage in Cardiff Bay, I searched for as many wildflowers in bloom as I could find. I spotted just ten species, but it’s quite a small area and the grounds are frequently cut and strimmed by the Council’s grounds staff, so I thought that was a good number for the time of year. And the list included a few species I don’t see elsewhere, like Viper’s-bugloss (very stunted from the too-frequent cutting), Black nightshade, and Common stork’s-bill.

The wildflowers in the video are Daisy (Bellis perennis), Dandelion (Taraxacum officinale agg.), Common stork’s-bill (Erodium cicutarium), Viper’s-bugloss (Echium vulgare), Groundsel (Senecio vulgaris), Nipplewort (Lapsana communis), Black nightshade (Solanum nigrum), Herb Robert (Geranium robertianum), Smooth sow-thistle (Sonchus oleraceus), and Hoary mustard (Hirschfeldia incana).

Mega: Lapland bunting!

I’m interrupting my series of posts about my long weekend birding in Portland because today I found a rather special bird, a Lapland bunting, quite a rare bird for Cardiff.

What first caught my eye was a Meadow pipit having a bath in the tiny pond on the Cardiff Bay Barrage and then, while watching and photographing that bird, I became aware that there was another bird very close by on the grass.

I took some photos but, as I’ve never seen a Lapland bunting before, I thought this bird was a very pale Reed bunting. It wasn’t until I got home and looked more closely at my photos that I realised I had something different. After consulting my bird guide, I sent a couple of images to our county bird recorder and he confirmed what I was thinking (and hoping).

As you might guess from its name, this little beauty is more at home in the Arctic than in Britain, though our recent chilly weather may well suit it. According to my RSPB Handbook of British Birds, only ‘about 700 birds are seen in Britain and Ireland most winters’ and it is ‘mostly an autumn and winter visitor, especially to the east coast of England and Scotland’. I guess the strong easterlies of recent days blew this one a little further than usual.

Unfortunately, the birders who went looking for it this evening weren’t able to re-find it but I’ll be up and out bright and early in the morning, hoping to see it again.
