Pūkeko is theNew Zealandname for the purple swamphen (Porphyrio porphyrio).
Pūkeko are:
· a member of the rail family of birds, which also includesthe takahe (the two birdslook very similar, although takahe are much heavier)
· around 51 centimetres long
· a deep blue colour, with a black head and upperparts, white feathers under their tail, and a red bill and legs
· laboured and reluctant flyers, but good waders, swimmers and runners
· aggressive and territorial
· mostly vegetarian, but also eat invertebrates, eggs, frogs, small fish, chicks and mammals, especially in breeding season where chicks are fedprotein-rich animals
· widespread. They have adapted well to urbanisation and are as at home inpasture and farmland as they are in wetlands
· cooperative breeders, with multiple male and female birdsoften sharing a nest and responsibility for incubation of eggs and the guarding and feeding of chicks
· protected but can be shot for sport during the shooting season.
· New Zealand status: Native
· In many areas, pukeko live in permanent social groups and defend a shared territory that is used for both feeding and breeding.
· All eggs are laid in a single nest and the group offspring are raised by all group members.
· Females are smaller than males, but similarly coloured. Juveniles are similar to adults but duller, with black eyes and black bill and shield that turn to red around 3 months of age.
· Territorial ‘crowing’ is the loudest and most frequently heard call.
· A variety of contact calls including ‘’n’yip’, ‘hiccup’ and ‘squawk’ are used between adults, and between adults and chicks. The defence call is a loud, shrill screech used when a harrier is nearby. A similar, but deeper and hoarser, call is made during aggressive interactions between individuals.
· Pukeko are found throughout New Zealand. They are typically found near sheltered fresh or brackish water (e.g. vegetated swamps, streams or lagoons), especially adjacent to open grassy areas and pastures.
· Pukeko are regularly seen near roadside and drainage ditches and along the margins of scrub or forested areas, from sea level up to 2300 m.
· Clutch size is typically 4-6 eggs per females and when multiple females contribute to a single nest the total clutch size can be as high as 18 eggs.
· Incubation is predominantly by breeding males, with some assistance from breeding females. All group members contribute to chick care.
· Chicks begin leaving the nest after 4-5 days, but are fed by adults for c. 2 months.
· In the North Island, laying can occur in any month, with a peak in August to November. In theSouth Island, breeding normally takes place between September and January.
· Pukeko are primarily vegetarian, but animal foods make up a small proportion of the diet. Most common foods are the stems, shoots, leaves and seeds of grasses sedges rushes clover and bullrush.
· They also eat garden vegetables and crop plants.
· Animal foods consist mostly of insects, spiders and earthworms however there are rare reports of pukeko taking larger prey such as frogs, lizards, fish and nestling birds.
