Program on the Environment

Plastic pollution is a threat to the ocean environment. It can cause economic loss, habitat damage, wildlife entanglement, ingestion, and invasive species transport. Reducing the amount of plastic we use daily can help limit the total amount that goes into the environment. The purpose of my project was to develop an alternative bird tagging method for Coastal Observations and Seabird Survey Team (COASST). Bird tagging requires a sequence of three plastic cable ties attached to the wings, legs, or bill in order to identify already tagged birds in future surveys. After the bird carcasses are tagged, they are then left on the beach. Increased volunteer concern of their bird tagging practices has led to the development of this project. To accomplish this task, I gathered volunteer suggestions and browsed the web for potential sources. I evaluated materials using a criteria checklist and then purchased sample materials. We then had several COASST staff and interns tag birds in the lab with our sample materials. We also met with current COASST volunteers to tag beached birds with them on their surveys. They provided a lot of insight on our samples and how they tag birds. From our evaluations, tests, and feedback we determined biodegradable flagging tape as a suitable alternative to cable ties.
