This Laysan Albatross chick starved to death because it's parents fed it too much plastic flotsam. This plastic flotsam filled the stomach, creating a feeling of being full when t wasn't. The parents collect the flotsam as it was used by flying fish to lay their eggs on. Some chicks manage to regurgitate the ingested plastic, I found regurgitated fishing gloves and a toothbrush, but often it killed the chicks. We found lighters, bottle caps, toys, pens, markers, toothbrushes and miles of fishing line in dead chicks. I kept the pen from this bird for use as a teaching aid.
Please don't throw plastic into the sea.
