The mistletoebird (Dicaeum hirundinaceum), also known as the mistletoe flowerpecker,[2] is a species of flowerpecker native to most of Australia (though absent from Tasmania and the driest desert areas), and also to the eastern Maluku Islands of Indonesia in the Arafura Sea between Australia and New Guinea. They also must live where there are trees and shrubs, so that they can build their nests. The bird eats a variety of different foods such as berries and assorted types of insects.[3]

Taxonomy

Genetic analysis of mitochondrial DNA of 70% of flowerpecker species showed the mistletoebird and red-capped flowerpecker (D. geelvinkianum) to be each other's closest relative.[4]

Subspecies

There are four recognised subspecies, which differ in geographical location and plumage details, primarily of the males:[3]

Description

The mistletoebird is small, 9–10 cm long and 7.5–11 g weight. The male is glossy blue-black above, with a red chest and a slight red undertail, and a black centre stripe running down its white belly. The female is dark grey above, with a white throat, light grey underparts, and just a touch of pinkish-red under the tail. The eyes, bill and legs are black; the bill is just over a centimetre long, slender, slightly downcurved and sharply pointed. Immature birds are similar to the female, but have an orange-pink bill instead of black.[3]

Behaviour

Feeding

The mistletoebird eats a variety of different foods. It commonly eats the berries of mistletoes (hence the name) and other plants. The diet also includes nectar, pollen, spiders, and insects.

The species consumes the fruit of Amyema quandang (grey mistletoe)[5] and other mistletoe species. By eating the fruit of the parasitic mistletoe, this bird is able to spread the seeds. When the birds eat the berries, the seeds pass through them, which takes anywhere from 4–25 minutes. Then when the birds excrete the seeds, they are sticky and easily adhere to the branch or trunk of a tree where they soon sprout.

Breeding

The female mistletoebird builds the nest by herself with no help from the male. The nest is made of crushed plants and spider webs, which holds it together and holds it to the tree. She will lay three or four white eggs in the nest and look after them till they hatch. When they have hatched both parents will feed them.
