Glenarm has a range of habitats to find birds including the Glenarm river and wood as well as the rich Antrim coastline, all of which have specialist species to see and enjoy.
Glenarm wood is the largest remaining semi-natural wood in the Antrim region. The soil type is a wide ranging from base-rich to strongly acid, creating diverse flora (plant life) which feed a variety of invertebrate, mammal and birdlife. Common species such as coal, blue, great and long tailed tit are joined by summer visitors such as Chiff-chaff, Willow Warbler and the increasingly scarce Wood Warbler, which is the highlight of the wood.
The wood boarders the Glenarm river which itself supports a mix of water invertebrates, fish and bird species. Birds include the Kingfisher and Dipper, both are indicators species of clean, healthy river systems.
The Antrim coastline is one of Northern Irelands great wildlife assets, being home to significant populations of Europe's seabirds. During Spring and Autumn migration the coast line acts as a highway for bird navigation. Species such as Whimbrel, Dunlin and Brent Geese move along the coastline, stopping to feed along our shores, estuaries and fields such as Carnlough beach or Glenarm hills. A highlight species of winter are the diver species such a Great Northern Diver and Red-Throated Diver which typically are seen far from the coastline during migration however during rough seas they shelter within Glenarm Bay. These normally wary, elusive and secretive birds can be seen incredibly close, even entering Glenarm Harbour which is comparatively quiet compared to other nearby busier ports which the birds avoid.
Another highlight of the bay and indeed Ireland is the Black Guillemot, a costal dwelling species of Auk, related to the Common Guillemot, Razorbill and Puffins that can be seen nesting at RSPB reserve on Rathlin Island. Black Guillemots unlike their relatives choose not to nest in huge colonies but in more isolated pairings. They nest within rocky holes along the shoreline and occasionally in holes within man-made structures such as Bangor and Glenarm marinas. Glenarm has established a significant colony which affords excellent views as they nest in the wall of the marina and feed along the tranquil coastline on benthic (sea bottom) fish such as Blennies, particularly the Butterfish.
