Previously considered a subspecies of the Asian koel, Australian koels are also known as Stormbirds or Rainbirds due to there propensity for singing more before rain.
As most members of the cuckoo family, they are considered "brood parasites" meaning they lay their eggs in other birds nests, rather than build their own. They usually choose honeyeaters, noisy friarbirds and red wattlebirds as the surrogate family.
The male Australian koel is mostly black with a red eye and grey bill. The females are a buff-cream colour on the belly and glossy brown above with white spots.
They mainly eat fruit and are often seen high in the trees feeding on ficus and other fruit.
