Southern boobook

Description

The morepork (Ninox novaeseelandiae),also called the ruru or Tasmanian spotted owl,is a small brown owl found throughout New Zealand and Tasmania.Described by Johann Friedrich Gmelin in 1788,it was for many years considered to be the same species (conspecific) as the southern boobook of mainland Australia until 1999.Its name is derived from its two-tone call.Four subspecies of the morepork are recognized,one of which has become extinct and another exists only as a hybrid population.The bird has almost 20 alternative common names,including mopoke and boobook – many of these names are onomatopoeic,as they emulate the bird's distinctive two-pitched call.It has dark brown plumage with prominent pale spots,and golden-yellow eyes.It is generally nocturnal,though is sometimes active at dawn and dusk,retiring to roost in secluded spots in the foliage of trees.The morepork feeds on insects and small vertebrates,hunting by pouncing on them from tree perches.The International Union for Conservation of Nature (IUCN) has assessed the southern boobook as being of least concern on account of its large range and apparently stable population.
