Janna Wynne, Veterinarian at the Los Angeles Zoo from 1996-2010 explains the issue of microtrash in the wild population of California condors. Microtrash is comprised of small pieces of trash including pop-tops, bottle caps, bullet casings, glass fragments and small bits of plastic. California condors are know to frequently pick up these items in the portions of their habitat they share with humans and return with these to their nests. Regurgitated there, these items may be consumed by condor chicks. This issue and the prevalence of lead toxicity in the species has created a necessity for condor program biologists to enter the nest of the wild condors routinely.
