The Wedge-rumped Storm-Petrel has a large range, estimated globally at 50,000 to 100,000 square kilometers. Native to Chile, Colombia, Peru, Ecuador, and Mexico, this bird prefers neritic, oceanic, coastal, or intertidal marine ecosystems. The global population of this bird is estimated at 400,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Wedge-rumped Storm-Petrel is Least Concern. More

although the Wedge-rumped Storm-petrels nesting in the Galapagos Islands are the exception to this rule and attend their nesting sites during the day. Storm-petrels display high levels of philopatry, returning to their natal colonies to breed. In one instance a Band-rumped Storm-petrel was caught as an adult 2 m from its natal burrow. Storm-petrels nest either in burrows dug into soil or sand, or in small crevices in rocks and scree. More

or Wedge-rumped storm-petrel Oceanodroma tethys I examined, nor on the extinct Guadalupe Storm-Petrel O. macrodactyla. Of the white-rumped, blackish-colored storm-petrels in the eastern Pacific, only the White-vented Storm-Petrel Oceanites gracilis possessed white at the base of any rectrix, and that species is easily distinguished by its small size and white belly. Here is a Band-rumped O. castro specimens from AMNH from 4 Apr 1891 at Wenman I., Galapagos. Note the broad black tip to the most visible white upper tail covert feather. More
