Species overview
About the Black-bellied Plover
This large plover breeds in the far north and uses coasts outside breeding. Nonbreeding birds are grayish above and pale below, while breeding adults develop much darker underparts. Its short sturdy bill and upright stop-and-look posture help distinguish it from many sandpipers. Dark armpit feathers are a flight clue in every plumage, best seen when a bird moves naturally.

Habitat & range
Scan exposed shoreline feeding areas and nearby resting places with binoculars. The tide changes which flats are available; remain on a safe established route.
Local observations
Mostly Pacific coastal flats and estuaries, especially the gulfs of Nicoya and Dulce; fewer birds occur on the Caribbean. Northern Plains records include Caño Negro. Inland occurrence is more local than the main coastal distribution. Oceanic Pacific: accidental visitor in the official Isla del Coco checklist, rather than ordinary year-round habitat.
When to observe
For migratory shorebirds, November–March is the broad nonbreeding observation window in Costa Rica, with southbound passage mainly August–October and northbound passage April–May. Individual species and sites vary; some birds remain outside these months. Check current local observations and the tide.
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
Compare its short bill with the whimbrel’s long curved one. Sketch both without changing their scale relative to the head.
