A walk along the Taff

On Friday, after I’d paid a visit to the tree I’m following, I enjoyed a stroll along the trail in Cardiff’s Bute Park that meanders through mature woodland alongside the River Taff. Despite this summer’s drought conditions, the recent rains have revived the local trees and plants so everything was looking wonderfully lush and vibrant.

A female Goosander sailing down river was a pleasant sight. Both males and females can often be seen on this part of the Taff from autumn through to spring.

Near the far river bank, a Grey heron stood tall on one of the many exposed rocks and boulders. The river is quite low at the moment.

There weren’t a lot of signs of autumn yet – only the leaves of the Horse chestnuts were yellowing and curling up and beginning to drop.

A Speckled wood was well camouflaged on the woodland floor. There weren’t many butterflies around, just half a dozen Speckled woods and a few Small whites.

A Mallard enjoyed a snooze near the river’s edge.

I liked the colours and patterns of the pebbles and the occasionally blue sky reflected in the river water.

This was one of two Mute swans feeding.

I’ve seen this particular Carrion crow many times before when I’ve walked this way. I know it’s the same crow, not because of how it looks but because it has virtually no voice. It tries to croak but hardly any sound comes out.

Most of the wildflowers have finished flowering but this Green alkanet was a pretty exception.

Just a few hints of autumn showing here. I love how this path meanders through these magnificent trees.

The woodland trail finishes just below Blackweir, where the current low water level means many rocks and boulders have been exposed. This was the perfect spot for a group of perhaps 20 Grey wagtails to fly-catch, and watching their aerial antics was the perfect end to my wander alongside the Taff.

Officially Mergus merganser – the name merganser is a hybrid eighteenth-century word obtained from the Latin root merg-, meaning ‘diving’, and anser, meaning ‘goose’, this beautiful bird is the Goosander. It used to be known as the Common merganser, and I’ve noticed some birders still call it that – old habits…. The bird has a ton of other vernacular names, like, from Sussex, dun diver; green-headed goosander, harle, and jacksaw, in Yorkshire; land cormorant (in Dublin); in Shropshire, pied wigeon; and, in Orkney, rantock. And then there are the understandable references to that long serrated ‘all the better to catch fish with’ bill: sawbill, in Stirlingshire; sawneb, from Aberdeenshire; and, from Suffolk, sawyer.

Their fish-catching habit is why Goosanders have often been persecuted, particularly by the fishermen who think the birds are theirs for the catching. Fortunately, the bird’s population has, thus far, not suffered unduly from this persecution and, from 1871, the year they were first known to have bred in Britain, the Goosander has gradually colonised most of Scotland and spread through much of England and Wales.

Britain has another merganser, Mergus serrator, the Red-breasted merganser, and the two species can be hard to tell apart. But the main thing to note is location – Goosanders are mostly freshwater birds and can be seen year round on rivers and lakes in many parts of Britain, whereas Red-breasted mergansers, although equally at home in fresh- and salt-water locations, are mostly seen in the winter months in coastal areas.

January on the Ely embankment

31 December 2017 I’m being a bit sneaky here as I managed to fit in one last walk along the embankment before the start of 2018 but after I’d written my December summary. So, on the last day of last year there were 5 Turnstones, 2 Redshanks, 2 Pied wagtails and 2 Grey wagtails, 1 Rock pipit and a couple of Crows.

1 January 2018 The very next day, New Year’s Day, I passed this way as part of a complete circuit of Cardiff Bay. It was a glorious blue-sky day but there were just 3 Turnstones present.

11 January This was another glorious day and another circuit of Cardiff Bay, though in the opposite direction. And it was a bumper day for the Ely embankment, with four Redshanks (including the ringed bird, shown above, which I’ve seen and written about previously), 6 Turnstones, 1 Pied and 4 Grey wagtails, and a Rock pipit.

16 January With 40-mph winds blasting down from snow-covered areas further north, the air temperature was hovering below zero when I walked along the embankment late morning. I wasn’t surprised, then, to find very few birds around – a single Turnstone that was wandering along half way up the embankment (not wanting to put its feet in the chilly water?), which was good for me as it was closer for photos, and just two Grey wagtails. There weren’t many birds on the river either, just a couple of coots, one Great crested grebe and several Black-headed gulls looking hopefully in my direction.

20 January I didn’t get out till late afternoon as it had rained most of the day, so the light was going as I strolled along the embankment path. But I was pleasantly surprised to see a few birds: my friends the Grey wagtails never disappoint (two of those); just one Turnstone poking away amongst the stones; and two Redshanks, including my little buddy the colour-ringed bird. Floating along the river were a Little grebe, a Great crested grebe and a pair of Goosanders – the latter were scared away by a boat cruising by and flew off towards the other side of Cardiff Bay, where I had seen a pair a week or so previously – perhaps the same birds.

25 January I detoured along the embankment on my return from a longer walk and was delighted to find six Turnstones (lovely to see so many), two Redshanks (but not my little ringed mate), two Grey and two Pied wagtails.

A tale of two goosanders

160328 goosander (2)

I watched a pair of goosanders (Mergus merganser) slowly making their way up one side of the River Taff today, frequently ducking their heads underwater in search of the fish, molluscs, crustaceans and amphibians that make up their diet. When they reached Blackweir, I expected them to drift back down the river but it seems they were determined to go further up steam.

That’s when it became apparent that the female can’t fly. Half of her right wing is missing. I doubt this is a birth defect and suspect a narrow escape from the mink that I have seen in recent weeks on the riverbanks in this vicinity.

The only way to cross the weir then was to walk as the flow of water, even though currently quite weak, was much too strong for swimming. The female had trouble getting out of the water up onto the rocks and then the concrete of the weir, but managed after a couple of tries. Her mate was very patient, and seemed very tender with her, touching her head with his beak, watching to see she was alright while also keeping a look out for danger. He would toddle a little way ahead, then turn and wait for her to catch up. Once he returned to her side as if to encourage her. It took perhaps 20 minutes but they made it and swam on up the river.

Trouble is, she is now very vulnerable to attack, especially from creatures like the mink but also from unleashed dogs (of which there are many in Cardiff). And the chances of these goosanders successfully breeding are also probably quite slim. My heart went out to these two little creatures, touched by the male’s gentleness with his disabled mate but saddened by their somewhat bleak future prospects.
