The Pacific koel (Eudynamys orientalis), also known as the eastern koel or formerly common koel, is a species of

Cuculidae. In Australia
, it is colloquially known as the rainbird or stormbird, as its call is usually more prevalent before or during stormy weather.

Taxonomy

The Pacific koel was

conspecific with the Asian koel (Eudynamys scolopaceus) and the black-billed koel (Eudynamys melanorhynchus).[4][6][7]

Eight subspecies are recognised:[5]

Description

The Pacific Koel can be identified by its black plumage, often tinted with blue and green, and red eyes. The species is sexually dimorphic: the female has brown plumage along the back with white spots and the underbelly is often cream coloured with fine black stripes. Young birds resemble the female but have dark eyes.

Distribution and habitat

It is found in forest, woodland, plantations and gardens from

Least Concern.[1]

Behaviour

The Pacific koel is a

frugivorous as adults.[9] A study of vocalization noted that the duetting behaviour may indicate the possibility of short-term pair-bonding in its otherwise polygynous mating system.[10]

In Australia, the presence of the species is regarded as a sign of the arrival of spring and the rainy season. It is also viewed as a nuisance due to the males' incessant calling throughout the day and night.[11][12] The calls indicate the start of breeding season and males would call repeatedly to mark their territory or communicate their availability to other females.[13]
