The Guadalupe Storm-Petrel is a small, entirely dark seabird that was endemic to Guadalupe Island, Mexico. It is critically endangered and possibly extinct, having not been definitively seen since 1912.
Where to spot
Historically bred on Guadalupe Island, off Baja California, Mexico. Any potential future sightings would be extremely rare in the waters surrounding this island.
How to spot
Identification would be based on its entirely dark plumage, relatively long wings, and subtly forked tail. Given its precarious status, any observation would be a momentous event requiring expert confirmation and luck during specialized expeditions to Guadalupe Island's waters.
When to spot
If it still exists, observation would be highly opportunistic and incredibly rare, potentially during the breeding season from spring to fall.

This species is a stark reminder of the devastating impact introduced predators, like feral cats, can have on island-nesting seabirds, leading to rapid declines and potential extinction.
