Varied and plentiful wildlife can be found in the environs of the river. In Wicklow, herds of deer can be seen, as well as swans, dippers, wild ducks, herons and kingfishers. At dusk, bats, owls and otters may be seen, while the mudflats of the estuary are favoured by black-headed gulls, redshanks and oystercatchers.[5] The rare goosander can be seen on the Slaney at Kildavin.
