The lead paper within the March 2022 problem of The Journal of Raptor Analysis presents a recent understanding of the conservation priorities for the world’s largest fowl of prey, the Andean Condor. In 2015, a crew of 38 condor consultants from all through the fowl’s South American vary in addition to the Wildlife Conservation Society, The Peregrine Fund, and different U.S.-based teams started gathering details about the fowl’s distribution, together with the place it roosts, nests, and feeds. The brand new paper, the fruits of their work, presents findings about:

– The condor’s historic vary. A 1990 examine estimated its historic vary to incorporate 2.36 million sq. km, however the brand new examine expands the realm by nearly 37 p.c, to three.23 million sq. km. Argentina accounts for 43 p.c of the brand new vary and Chile 23 p.c, whereas Venezuela, the northernmost nation within the vary, holds lower than 1 p.c.

– Birders’ reviews to eBird. Identified distribution factors for the condor expanded considerably with greater than 8,200 distribution factors that birders reported as much as Might 2016 in eBird, the net bird-record challenge.

– Extirpated areas. The condor is now not present in about 7 p.c of its historic vary. The areas are scattered from Colombia to southeastern Argentina.

– Conservation items. The consultants within the group recognized 31 Andean Condor Conservation Items — areas that needs to be preserved to satisfy the wants of the wide-ranging fowl. A number of the areas are adjoining to one another in neighboring nations, permitting them to be mixed and the full diminished to 21 items. They vary in dimension from 837 sq. km to greater than 298,000 sq. km. A couple of of them haven’t any formal protections whereas as much as 57.8 p.c of others have protections in place.

The authors say standardized census strategies needs to be applied all through the fowl’s vary and that better worldwide cooperation is required “as Andean Condors don’t acknowledge borders and require conservation throughout varied jurisdictions.”
