You can tell that I took this photograph in an area popular with walkers because the coots have incorporated a walking pole into their nesting platform, here by the dam head at Newmillerdam Country Park.
The juvenile coot in the foreground hasn’t yet developed the bulging forehead of its parents, nor has the colour in its legs begun to show.
But its flanged feet match the adults in size; ideal for trotting over mud and floating vegetation and almost as useful for swimming.
