Rat, West Park. Pre-pandemic, any rat spotting someone nearby would immediately head for the cover of some undergrowth.
This one just carried on wandering around, pausing two or three times to face me directly, trying to stare me out.
When coot chicks hatch there is a red patch in the down above their beaks, presumably a trigger for their parents to feed them.
As the young get bigger and more independent, this red patch is replaced by down the same colour as covering the rest of the bird – the stage this year’s first broods have now reached. These pictures from West Park
