Otter spraints neatly deposited on a mooring bollard by the canal at the Bingley Arms, Horbury Bridge. I’ve yet to see one of the otters but I was told that they’d been picked up on security cameras near the river.

Writing in British Birds in 1952, G Warburg described some remarkable communal behaviour in breeding Redshanks when dogs and, once, an otter, Lutra lutra, approached;
‘up to 20 packed close round intruding mammal, following it carefully with bowing and bobbing movements (in the case if L. lutra, silently) when dog ran, birds hovered overhead, giving Chip-calls.’
Warbury 1952 and Grosskopf 1959, quoted in Birds of the Western Palaearctic, 1983
