Any of the headlands are worth searching for tired migrants, as well as offering sea watching for birds. In summer, head for the offshore islands. Kerry is the world headquarters for breeding Storm Petrels, and has big colonies of Gannets, Manx Shearwaters, Puffins and most other seabirds. Many of the islands are readily accessible to day-trippers, the most famous being Great Skellig. Watch out for Ring Ouzels, Choughs, Ravens, Peregrines and Rock Doves, particularly around the Gap of Dunloe.
Autumn is the time for the estuaries and headlands.
Tralee Bay and the Shannon estuary all have large numbers of ducks geese and waders. Light-bellied Brent Geese and Wigeon are common around Castlemaine harbor and Tralee Bay. Of the three estuaries, Tralee is probably the best for a good mix of species, many in large numbers. Tralee also has a habit of pulling in rarities at any time of year, and is an area well worth working. To the north lies Akeragh lough, famous as a beacon for American migrants, particularly waders.
