Field notes
- During the peak breeding season, the bird's bill transforms from a dull yellow to a vivid cobalt blue with a black tip.
- It exhibits a dramatic visual 'transformation' when taking flight, as its streaked brown body is suddenly dominated by snowy white wings.
- The species is primarily crepuscular, being most active during dawn and dusk while remaining motionless in cover during the day.
- Courtship displays involve the raising of long, lanceolate plumes on the nape and back that are characteristic of the Ardeola genus.
- They are colonial nesters that often establish sites within mixed-species heronries located in dense reedbeds or trees over water.
Habitat
Freshwater marshes, swamps, lake margins with thick vegetation, and flooded rice paddies.

Southern Europe, Western Asia, and Africa, with Palearctic populations migrating to Sub-Saharan Africa for winter.
