Spokane Bay - mats of algae and hints of migration

This week's story from Spokane Bay is about bird migration and algae. The birds: yellow-rumped warblers in the willows, pelicans and mallards on the bay, American goldfinches in the marsh elder, and a merlin hunting overhead. The algae: it's a possible trap for a kayaker or an unwary duck, but it's also a habitat for damselflies and even-tinier insects.
