Huia

Huia, or New Zealand Wood Crow (Heteroloeha derdirostris), a rare New Zealand bird, by some authorities classed as an aberrant crow, and by others as a starling. It is remarkable for the fact that the bills in the two sexes differ in shape and size; hence the male and the female were formerly reckoned as distinct species. The former uses his strong wedge-shaped bill to chisel away decayed wood, while the female, whose bill is slender and curved, picks out the larvae, on which they feed, from their holes.
