It’s all about the birds at the moment, with autumn migration in full swing and with my local area fortunate to be enjoying visits by some stunning birds, like this one.

The day I saw the three phalaropes there was another cracking bird at Cardiff’s northern reservoirs but it was a bit overshadowed by the three rarities, and I doubt many birders bothered to walk to the far end of the adjacent Llanishen Reservoir to see this one, a beautiful juvenile Garganey (Anas querquedula).

An explanation is necessary here; I actually visited the reservoirs the day before I saw the Grey and Red-necked phalaropes, as one Grey phalarope had been reported that day. But it was literally blowing a gale so I had difficulty staying upright, let alone trying to scan the choppy waters with my binoculars to find a small grey bird. In fact, it was so windy that a marquee, which had been pegged close to the visitor centre, had come loose from its pegs and blown across the path to the reservoir where the phalarope had been reported, so the path had been closed off for safety reasons. Seeing that, I gave up looking but, enjoying the fresh air and wanting the exercise, I stomped briskly around Llanishen Reservoir. And, during that walk, I spotted the Garganey (the photo below was taken that first day) but, as I’m a bit hopeless with female/eclipse/juvenile ducks, I didn’t initially trust my identification skills. Amazingly, I’d got it right this time.

A second Black-necked grebe for 2024

This little beauty first appeared on Cardiff’s northern reservoirs, with another of its kind, on 31 August. As I’d already seen a Black-necked grebe (Podiceps nigricollis) this year in Cardiff Bay (Another rare grebe, 24 January) and because I’m not keen on the crowds of school holiday visitors, I put off visiting – and crossed my fingers that they would stay a while – until this week.

One of the grebes only stayed a day or two but the other is still present, despite being frequently disturbed by the human water traffic on Llanishen Reservoir. I was lucky to get close, though fleeting views before the bird was scared much further away by a trio of your paddleboarders.

Red-necked grebe

This handsome bird, a Red-necked grebe (Podiceps grisegena), was first sighted on north Cardiff’s reservoirs last Thursday 11 January by our county bird recorder, who lives very near this location. He says this bird is only his ninth ever at the site and the first since September 2001 – by anyone’s definition, a local rarity.

The reservoirs are just a train ride and a half mile walk from where I live so I headed up on Thursday to see if I could spot it. I did, firstly on the much larger Llanishen Reservoir from where it flew across to neighbouring Lisvane Reservoir but, at least while I was there, it remained very distant. As is the way with birding, later that day the grebe moved very close to the reservoir edge nearest the café, so afternoon visitors got very good views of the bird.

As I needed to go to north Cardiff again this past Monday on another matter, I thought I’d visit the reservoirs for a second look. And this time my luck was in, both with the sunny, less windy weather and with the grebe, which had returned to Llanishen Reservoir but, fortunately, was cruising around much closer to the western edge.

According to the RSPB website, ‘Less than 20 individuals spend the summer in the UK each year, with numbers increasing slightly in the winter when birds move here from colder Europe’, so I feel particularly privileged to have spent time observing and photographing this Red-necked grebe. Oh, and if you think its neck doesn’t look very red, it’s because the bird is in its winter plumage. Take a look at the RSPB website for photos of how stunning this bird is in breeding plumage.

A lovely Loon

Finally, on Thursday, we had a break in the almost constant procession of wet and windy weather that made miserable many of my winter walks in December. To make the most of this, I caught the train to north Cardiff and enjoyed a wonderful walk around the recently reopened Llanishen and Lisvane Reservoirs, through the still muddy Nant Fawr woodland, and on down to Roath Park Lake. The highlight for me of this walk was getting relatively close views of the Great northern diver (Gavia immer) (what my American viewers would call a Common loon) that has been overwintering in Llanishen Reservoir. The bird was still some distance from me so my photos don’t do justice to how beautifully patterned this bird is but it was a pleasure to watch its constant diving.
