Pico expects every Little Blue Heron to be blue. Tati discovers that young birds tell a different color story.
Species overview
About the Little Blue Heron
Adults have slate-blue bodies and purplish heads and necks. Young Little Blue Herons are white, later passing through a patchy blue-and-white stage. These herons usually search quietly for small aquatic prey. Age can change identification clues, so an all-white bird should not automatically be called an egret.

Juveniles are white, unlike the illustrated adult
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
Widespread in lowland wet habitats on both slopes, with small numbers reaching the Central Valley. Mostly migrants and nonbreeding visitors, with limited local breeding. Oceanic Pacific: rare visitor in the official Isla del Coco checklist, rather than ordinary year-round habitat.
When to observe
Numbers and locations can change with water levels, feeding opportunities and seasonal movement. Check recent local observations; a regional record does not promise a bird on a particular visit.
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
Draw two simple outlines labeled adult and juvenile. Use different colors to show why age matters.
