A Bar-headed Goose is hard to find at Lydney boating lake, in fact, it's hard to find outside of the Himalayas. This one must have flown here from Slimbridge (an escapee). It is a really high flyer, the highest known of all birds.
The Coal Tit lives in the trees, mostly coniferous. It eats insects and seeds. In the winter it is commonly seen in gardens, when it takes away seeds from the feeders and will go and hide it.
