Plumage & appearance
Adult males typically have blue-grey upperparts and head, with a white underside finely barred with dark grey. The wings often show rufous or brown tints on the flight feathers, and the long tail is dark with white spots.
Ecological significance
As a brood parasite, it plays a complex role in the population dynamics of host species. It also helps control insect populations, particularly hairy caterpillars that many other birds avoid.
Conservation status
Least Concern (Global), though some regional populations (like in the UK) are in decline.
Observation tips
Listen for the iconic two-note call during may and June. Look for them perched on fence posts or flying low over open heathland or reed beds. They are shy and often easier to hear than see.
