BWI Cuskinny Marsh Nature Reserve is not a zoo or wildlife park so apart from having a great time with nature we cannot guarantee anything ahead of your visit. There is always something to see on a visit and the more you visit the more you will see. During the spring and summer look out for flowers and insects and also breeding birds such as the Mallard, Sedge Warbler, Willow Warbler. In the Autumn and Winter keep an eye out for winter visitors such as Wigeon and Gadwall on the lagoon and Great Northern Divers, Great Crested Grebes, Black Guillemots, Brent Geese and if you are lucky an Otter or Grey/Harbour Seal in the Bay area.
