I'd like to see some analysis of the particular lead. For instance, if the condors had ingested lead from waterfowl, the deer hunters wouldn't be the problem.
Generally, the furry critters clean up gut piles or lost quail/doves before the buzzards have a chance. Buzzards tend to spot natural-cause deaths earlier, if they're out in open areas. Deer are more likely to be killed in brushy or wooded areas, and not as often out in the wide open country with no cover.
