The mistletoebird (Dicaeum hirundinaceum), also known as the mistletoe flowerpecker, 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. The mistletoebird eats mainly the berries of the parasitic mistletoe and is a vector for the spread of the mistletoe's seeds through its digestive system. The male is glossy blue-black above, with a red chest and a slight red under-tail, and a black center 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 centimeter long, slender, slightly down-curved and sharply pointed. Immature birds are similar to the female, but have an orange-pink bill instead of black. There is a variance in size and color across their distribution. The adult mistletoebird is smaller in the north of its distribution and females in the north have lighter colored underparts compared to darker ones in the south.
