Birds visiting the area include Brent goose Branta bernicla, common eider Somateria mollissima, red-breasted merganser Mergus serrator, pomarine skua Stercorarius pomarinus, Arctic skua Stercorarius parasiticus, Arctic tern Sterna paradisaea and Brünnich's guillemot Uria lomvia.

Notable exceptions to food resource generalism are lemming predators (e.g., least weasels – Mustela nivalis, and several owls – Asio, Nyctea spp., raptors – Buteo spp., and skuas – Stercorarius spp.) and a number of host-specific phytophagous insects (e.g., aphids – Acyrthosiphon spp. and sawflies – Symphyta).
