Eurasian hobby
Three areas of Haldon have been designated as Sites of Special Scientific Interest (SSSIs). The largest is Haldon Forest which covers most of the high woodland north of the A380 road as far as the Haldon Belvedere. This area is primarily designated because of its bird life. It is a nationally significant habitat for the European nightjar (Caprimulgus europaeus) with about 80 pairs breeding here. In addition six bird of prey species breed here: the nationally rare European honey buzzard (Pernis apivorus), the nationally scarce goshawk (Accipiter gentilis), the Eurasian hobby (Falco subbuteo), Eurasian sparrowhawk (Accipiter nisus), common buzzard (Buteo buteo) and common kestrel (Falco tinnunculus). In addition, there have been a total of 35 species of butterflies recorded, including the nationally rare high brown fritillary ("Fabriciana adippe") and pearl-bordered fritillary ("Boloria euphrosyne"). Many moth and dragonfly species are also present.
