Species overview
About the Yellow-crowned Night-Heron
This sturdy heron often hunts crabs and other crustaceans around coastal wetlands. Adults have a dark face, pale cheek stripe and creamy crown above a gray body. Young birds are brown and spotted. Despite the common name, individuals may feed by day or night, depending on local conditions and food availability.

Habitat & range
Scan shallow water, quiet mangrove channels and vegetated wetland margins from an established viewpoint. Follow a local guide’s directions around estuaries.
Local observations
Both lowland slopes, especially mangroves and larger rivers. Usually less numerous away from coastal feeding habitat; resident birds are joined by nonbreeding visitors. Oceanic Pacific: casual visitor in the official Isla del Coco checklist, rather than ordinary year-round habitat.
When to observe
Often active near dusk or at night, although daytime observations occur. Respect park opening hours and observe resting birds quietly; do not use flash, playback or a night search to disturb them.
Conservation & care
Give feeding and resting birds space. If a bird stops feeding, repeatedly looks at you or moves away, increase your distance. Keep dogs away from flocks, avoid playback and feeding, and leave nests and natural shoreline debris undisturbed.
Observation activity
Watch from a fixed spot and record whether a bird is resting, walking or searching. A name does not replace observation.
