- The Spotted Owl was not going away before man started clearing and logging its
- forests. However, this sort of observation is made of the California Condor.
-
- Modern factors, such as DDT, caused its the Condor's extinction in the wild (its
- now been re-introduced) but it had been in decline for thousands of years.
- This decline may still have been caused by man. The Pleistocene extinctions
- of mega-fauna likely played a large part in the Condor's decline. The cause
- of these extinction is hotly debated, as they came in a time of climatic
- change, but many think man was at least partly to blame.
-
- Some say these extinctions doomed the condor and the mountains of California
- and Baja were a dead-end for the Condor. Its seems to me they could equally
- well have been a refuge which would have allowed the Condor to weather the
- current unfavourable condition as it may have done many times in the past
- when factors such as climatic change produced unfavourable conditions.
