The end of October brought with it the end of our fall trap up season. The effort went smoothly as the field crew found its groove. Ultimately, we were able to successfully treat the condors that came through with lead poisoning and observe some hopeful trends within our Central California Condor flock.
September and October have historically been the months when Big Sur's condors have had the highest levels of lead in their bloodstream. This was likely due to the use of lead ammunition for deer hunting in that time of year. Since the lead ammunition ban of 2007 this trend may be changing. This year we observed higher blood lead levels during our spring trap up than in the fall. Additionally, more birds were treated at the LA Zoo for high lead exposure earlier in the year. We are happy to see some positive steps being made in the realm of condor conservation and hope that the threat of lead poisoning continues to lessen for this flock. We are thankful to the recreational hunting community for their cooperation.
The four pre-release chicks (559, 566, 569, and 583) have been adapting well to their surroundings and the social hierarchy of the free-flying flock. The chicks had the equivalent of a speed dating opportunity this month as many of the wild birds spent some time with them in the flight pen. They appear to be eating very well and learning their place at the bottom of the condor totem pole. These four young ones will be released following the imminent completion of PG&E's removal of the Anderson Peak overhead power line. This important project will reduce the risk of electrocutions for condors and eagles. Our field crew has been monitoring construction efforts daily and working with helicopter pilots to ensure equipment and condor safety. We are excited to see such an effort made on behalf of endangered wildlife and look forward to introducing our chicks to the slopes of the Central California Coast.
Eventually, it appeared as though the Condors were fed up with our antics during trap up. At the end of this month most of our Big Sur birds headed east to spend some time around
Pinnacles National Monument. Among those few who stayed behind was our ever-determined female 306. Only she remained in
251 and
222's territory. We may have a trio on our hands once again next breeding season, but recently, 222's old mate,
204, has been showing interest in a nearby canyon and possibly setting up a new territory, maybe 222 will join him, but it's still too early to say.
It has been a clear, sunny October which will be missed as the cold of November begins to set in. We will, however, take a collective sigh of relief when the fire season officially comes to an end.
Until next time,
The Condor Crew
