Geographic Range [top]

Range Description:	Oceanodroma markhami breeds on the Paracas peninsula, Peru, and additional colonies are likely on other islands and in the coastal desert of Peru and Chile^2,3. It occurs in tropical waters of the eastern Pacific Ocean, spending July-September (and possibly longer) in warm equatorial waters, and January-July in the cooler waters of the Peru Current⁴. Data on overall numbers, trends and threats are lacking, but a minimum of 2,305 pairs were present on the Paracas peninsula in 1992⁶.
Countries:	Native: Chile; Colombia; Costa Rica; Peru Vagrant: French Polynesia; Panama Present - origin uncertain: Ecuador

Habitat and Ecology [top]

Habitat and Ecology:	Birds on Paracas breed in small, dispersed colonies up to 5 km from the sea on sloping ground, usually where saltpetre deposits offer fissures and holes for nesting⁶. While Paracas birds fledge in November, grounded fledglings are mostly found near Iquique, Chile, in March-April¹. They feed opportunistically both inshore and offshore on fish, crustaceans and cephalopods⁵.
Systems:	Terrestrial; Marine

Conservation Actions [top]

Conservation Actions:	Conservation Actions Underway None are known. Conservation Actions Proposed Search for breeding colonies in Iquique region, Chile (especially around Salar Grande) between January-May, listening for adults flying near colonies at night and checking for active burrows during the day⁶. Monitor the colony at Paracas. Study its ecological requirements and threats.
