Keep it crumb clean
Be Aware:

Memorial Park is a crumb-clean area.

Memorial Park is home to the endangered marbled murrelet who are sea birds, but who nest high in the redwood canopy. Any food left in the area attracts Steller's jays, the main predator of marbled murrelets, who knock the murrelets from their nests and eat the one egg they lay per year.

Feeding any wildlife—even inadvertently—is dangerous to you, other humans, and to the fed animal. (And it's against the law.) Visitors to Memorial Park are required to watch this video from the Redwood National and State Parks services to learn how to keep a crumb-clean camp or picnic site and how to properly store all food and other "smelly" items.
