Oyster Catcher?

Oyster Catcher?

Observation - Oyster Catcher? - Global. Description: This bird has a white band on its throat which I can't say I've noticed before on other Oyster Catchers. I've looked on the web and seen a few birds with the same thing but can't find an explanation as to why. Is it a jeuvenile? Does anyone know please
