Copeland Islands lapwing and snipe may be found further inland. Here the taller vegetation, interspersed with open areas, provides an ideal breeding habitat. Birds of prey favour the islands when the breeding season is over. Hen harrier, sparrowhawk, buzzard, kestrel, merlin and peregrine falcon are all seen regularly. Mammals, such as the grey seal, common seal, harbour porpoise ("Phocoena phocoena"), bottlenose dolphin ("Tursiops truncates"), minke whale ("Balaenoptera acutorostrata"), harbor seal ("Phoca vitulina"), common dolphin ("Delphinus delphis") and otter ("Lutra lutra") have been reported from the Copeland Islands.

A nova was discovered by amateur astronomer Koichi Itagaki, Nova Delphini 2013. Giants within our galaxy in Delphinus aside from Delta, Gamma and Epsilon include: Its rich Milky Way star field means many modestly deep-sky objects. NGC 6891 is a planetary nebula of magnitude 10.5; another is NGC 6905 or the Blue Flash nebula. NGC 6934 is a globular cluster of magnitude 9.75. At a distance of about 185,000 light-years, the globular cluster NGC 7006 is at the outer reaches of
