What is microtrash?
"Microtrash refers to small bits of trash such as broken glass, bottle caps, can tabs, and other smaller, broken down pieces of trash that can be ingested by condors [and other vultures]. Condors are curious birds and natural scavengers and are attracted to small bits of trash that stand out from its surroundings." USFWS California Condor Recovery Program
vultures at risk
Additionally, when microtrash is brought to the nest and regurgitated by an adult condor, it is often ingested by condor chicks. The microtrash can get stuck in the gastrointestinal track of young condors and cause impaction, preventing the birds from digesting food, resulting in starvation and death.
