Trash collection in highway pullouts is also a regular part of our threat management. The targets here are small pieces of trash, we call micro-trash. Whether condors mistake micro-trash for the calcium-rich bones they need, or are simply attracted to novel objects, trash ingestion is a threat to condors, and particularly to condor chicks waiting in the nest. In 2009, we lost a condor chick due to ingestion of trash brought to the nest by the parents. To keep things clean for the condors and our community, we invite volunteers to join us for seasonal trash pick-up events at scenic pullouts often frequented by condors.
