Ruddy-headed Goose in its breeding grounds

The Fuego Patagonia population of the Ruddy-headed Goose Chloephaga rubidiceps is in serious danger of extintion. During the breeding season the distribution of this bird is restricted to the southern end of Chile and Argentina. Big part of the breeding pairs are found in the Region of Magellan, Chile. The reasons of its decline are due in among others to the introduction of the Grey Fox Pseudalopex griseus, in Tierra del Fuego Island . During autumn, an important part of the Ruddy-headed Goose population migrates northward, using a little area in the south of the Buenos Aires Province as wintering grounds.

Since 1996 Ricardo Matus has participated as an independent researcher in the project coordinated by Wetlands International and funded by CMS (Convention on Mygratory species / CMS-UNEP) focused on the study and conservation on the scarce Ruddy-headed Goose Chloephaga rubidiceps continental population in its breeding grounds. Through this project it being possible to determine the current distribution of the species, estimate the mainland population, determine new concentration areas and monitor their migratory movements.

As part of the concrete measurement protect the species Ricardo Matus and Olivia Blank have proposed the creation of a protected area in one of the “hot spots” of the species in the breeding grounds: San Juan River mouth, Magellan Province, Chile.
