Just spotted this little guy at Thornes Park in Wakefield. Didn't know we had any in these parts apart from Lotherton Hall and the likes? Are there a lot in the area? Could only spot him and no females, looked a lonely little guy!
Couple of feral populations of Mandarins. One based around Adel Dam in North Leeds and one on the Wharfe between Adingham and Bolton Abbey. Max numbers Ive seen 14 birds at Adel and c30 birds at Bolton Abbey. Not aware of any other groups in the area
They are regular in Harewood Park (source of the local birds?) with a build-up each autumn, peaking at just over 100 birds in some years. It's still odd to see ducks perching in trees, as they do along the streams and around the lake.
Egyptian Geese have bred there for the last couple of years, so expect that population to increase locally as well.
