Re: [cobirds] Condor at Mesa Verde

Dear Cobirds:

The CBRC does not have a stated policy on how it handles introduced (or in this case reintroduced) species.  In the case of Condor N8, however, I believe this is clearly a case of a bird that is not a "countable" species on the Colorado state list.  N8 was hatched in captivity and released in the wild.  In effect, that is much akin to a falconer losing a Gyrfalcon or Harris's Hawk. While both of those are native (albeit rare) species that occur in Colorado, the hatched and raised in captivity negates those individuals from being considered countable for listing purposes.  Furthermore, with regard to the ABA rule, this bird is reasonably separable from wild born individuals due to its wing tag clearly identifying it as a captive-raised individual.

good birding,

Doug Faulkner

All,

 

The ABA Rules Statement below has two parts.  There is an "or" and not an "and" connecting the two parts of the rule statement so the way I interpret it, the California Condor from SW Colorado meets the criteria about the established population of California Condors on Vermillion Cliffs, Arizona.  The CO bird flew from that established population to SW CO.  Many of the other birds at Vermillion Cliffs portion of Grand Canyon were also introduced from the San Diego Zoo and at least one pair of the Grand Canyon birds has hatched young.

 

(vi) an individual of a reintroduced indigenous species may be counted if it is part of a population that has successfully hatched young in the wild which is reintroduced into an historic range of the species may be counted when the population meets the ABA Checklist's definition of being established or when it is not possible to reasonably separate the reintroduced individual from a wild-born individual;

since it was released from the San Diego Zoo two years ago.
