Williamson pays close attention to the calls and cries of birds and animals, and here he distinguishes between the mutual call of a dog and a bitch otter. I found the description of White-tip’s cry extraordinary.
‘White-tip answered him. Her cry was like wet fingers drawn over a pane of glass. Tarka’s cry was deeper, more rounded, and musical.’
