Appearance
Males are olive green with a dark purplish sheen on their head and black outer wing and tail. While females are a duller olive brown with a blue sheen on the head and yellowish-white curving from the base of the bill to below the eye. Both have a notably red eye. They are about 17–20 cm from the tip of their beak to the end of their tail. Females weigh about 25 g and males 32 g. Juvenile females have brown eyes and a light yellow cheek stripe. Juvenile males have dull brown-black outer wing and tail feathers.Distribution
The bellbird is found throughout both the main islands of New Zealand apart from the north of the North Island. Its population and distribution had been seriously affected by the introduction of European-style farming, which has led to the removal of native forests . Another important factor is the introduction of predatory species such as cats, weasels, stoats, ferrets, rats and food-robbing species like wasps. Predators either eat the birds or consume eggs, while food robbers compete with the bellbird for its natural food sources of nectar, honeydew and insects. The decline occurred around the same time as many other New Zealand species, but for unknown reasons was reversed and the species is still common across much of New Zealand.Reproduction
Breeding occurs from September to January where two broods can be produced. Their nesting habits are similar to the tui in respect to colour of eggs, clutch size and incubation. They generally lay three to four eggs with pinkish brown spots and blotches.Food
Bellbirds feed on nectar, fruit and insects. Insects are important for females and their chicks during the breeding season. As honeyeaters they play an important part pollinating numerous native plants such as mistletoe, fuchsia and kowhai.References:
