The California condor is making a comeback but it isn’t out of the woods yet, according to federal wildlife officials.

A survey of condors found 405, a far cry from 23 in the early 1980’s. Condors remain on the federal endangered species list. The federal recovery plan calls for 450 condors and three 150-bird populations in order to be considered for delisting.

An OregonLive story today reports that condors still face challenges like pesticide residues in carrion they eat, wind farm mortality, and lead poisoning from feeding on gut piles from animals that were shot with lead ammunition.
