First, there were two Goldeneyes in Cardiff Bay, probably females (though juvenile birds also resemble females, and I’m not sure when they get their adult plumage).

Then, a male turned up.

And they all fairly quickly found each other and mostly hung out together.

Then, in the blink of an eye, another one appeared, and so there were four little Goldeneyes cruising around Cardiff Bay.

They are very entertaining birds to watch, very active, so let’s hope they remain for a while yet (though, sadly, there is a great deal of human disturbance in the Bay, with power boats, kayakers and paddle-boarders all disturbing the local water birds).
