Had an early morning walk along the Union Canal and Water of Leith to greet the new year. Lovely crisp, clear day with fresh snow underfoot. Photo'd this heron perched on the roof of the local Booker Store above the river, having a break from fishing duties.
Also saw two female goosanders diving throughout a stretch of the water further down, which set me thinking about a chat I had with an ecologist from the Scottish Environmental Protection Agency last year. He told me they'd surveyed a city stretch of the river recently and found literally hundreds of the non-native bullhead, against only a few brown trout. Bullheads seem to be generally bad news for at least some native species but no doubt they provide food for fish eating birds and mammals.
