I've consolidated all the posts about the "eagle killer," cyanobacteria growing on hydrilla. Eagle exposure can occur from being in contact with water where it grows or by eating waterfowl, such as coots, that have eaten the hydrilla. The 1st article is a good "CSI" account of how it was found and where the scientific name comes from.

Well, this is very scary news. Infected coots are killing bald eagles.

"Iowa waterways are a disgrace." So says a Des Moines Register editorial with regard to toxic blue-green algae blooms. Florida had issued a similar warning in early summer about bald eagles being killed after eating coots that had ingested the same cyanobacteria. Evidently, eagles can directly ingest the toxic bacteria just by fishing or drinking from contaminated waterways.

Update: Basically, nothing has changed but the warnings still apply because coots are now returning to lakes where they will overwinter. While blue-green algae blooms are up in Iowa, there's no specific info on the cyanobacterium responsible for eagle deaths.
