Antarctic Petrel vs Pintado Petrel

In short

The Antarctic Petrel and Pintado Petrel are both medium-sized seabirds found in the Southern Ocean, but they can be distinguished by their distinct plumage patterns. The Antarctic Petrel has a more uniform brown and white pattern, while the Pintado Petrel is notable for its striking black and white 'checkerboard' appearance.

Identification tips

Habitat

Both species are pelagic and are typically found in the Southern Ocean. They often overlap in range, especially around Antarctic waters.

Voice

Vocalizations are not typically used to differentiate these species in the field, as both are generally silent at sea.
