Local resident Wren Gilgan heard a racket outside his door one day and realized a robin was frantically trying to keep a martin from its nest.
Martens are omnivorous animals related to wolverines, minks, badgers, ferrets, and weasels.
Their diet consists of squirrels, mice, rabbits, birds, fish, insects, and eggs. Martens are solitary animals, meeting only to breed in late spring or early summer.
