MOUSE MURDERER

Although I might have had a better view of the nest by stepping on the bank, 1 didn't do so, because bird-nesting boys study the signs in the hedgerow grass as much.as anything else, and the nest would have been plundered before long.

One often lists predators, thinking of jays, crows, owls, rats, stoats and weasels, etc., but forgetting the smaller creatures every bit as eager for blood.
