Firstly, is a colour-ringed bird that I saw at the start of January on the flooded river Severn in Worcester.
Mute Swan
This bird, was, as I said, part of a large flock of Mute Swans (100+), that can be found year round on the River Severn in the centre of Worcester. A good number of these birds are colour ringed, and this one, 95G, was seen on Sunday 3rd January 2016. I reported the bird to the BTO (link here), and heard back that it had originally been ringed, as a cygnet, in July 2013, about 1 km away from where I saw it! It was first reported in the "Worcester flock" on 16th March 2014, and hasn't been reported anywhere else.....yet.
The second interesting Mute Swan, is one that I saw last Sunday, whilst walking around Clumber Park with Jayne. At the time I didn't think much about it, just that it was sitting on the tree trunk and looked quite photogenic! I took a picture, and posted it here, and on Twitter. I received a reply to my tweet, saying that it was a "polish" Mute Swan! I didn't think much about this again, until I read an interesting article in the BTO's Bird News tonight, asking for sightings of "polish" Mute Swans!
Mute Swan
Apparently, this is the name given to a leucistic version of Mute Swan, which is caused by a recessive gene. The birds are white as cygnets, and, when adults, have greyish-pink legs, instead of the usual black ones. Most birds have been recorded in the south of England, mainly in Kent, Essex, Suffolk and Norfolk, so, if this is such a bird, it might be quite a good record. Anyway, I've sent the details off, and will update when I hear back.
Perhaps Mute Swans are interesting after all!!
