The Pacific kingfisher is characterized by its vibrant blue and green plumage with a distinctive white throat and belly, creating a stark contrast with its more colourful parts. The back and wings are a deep blue, which may shimmer in sunlight, while the head and nape feature a darker blue shade, providing a stark backdrop for their black eyes and minimalistic facial markings. They have a long, slim, pointed beak, perfectly adapted for catching prey, and sturdy short legs that are typically a dull grey.
