The condors number close to 450, over half of which are wild. While an outright ban on lead ammunition won’t kick in until 2019, aggressive public education has helped safeguard the species—inland at least. But scientists have found a new threat to the reestablished condors:

According to Wikipedia, which shows a comprehensive listing of all the bird species seen naturally in the state of California, as determined by the California Birds Records Committee (CBRC), as of 2009, there are 641 species native to the state list. Fifteen of these species are introduced, species that are non-native to California but now have established populations. Two of these species are extirpated, species that are native to California but no longer have established populations here, although they still do in other places.
