Jays
There are five species of jays in Costa Rica: the white-throated magpie-jay, brown jay, black-chested jay, silvery-throated jay, and the azure-hooded jay. All of them display shades of blue except for the brown jay. They are typically noisy foragers, save for the black-chested jay, and omnivores. The white-throated magpie-jay is perhaps the most well-recognized.
