Hello, we need your help with a research project! We are a research group at the University of Michigan that does work on a green algae species called Haematococcus. This organism is frequently found to be responsible for red discoloration in bird baths and small shallow ponds. It is thought to be spread by birds bathing, and is not likely to be toxic for the birds. We would like to get an idea of spread (locations) of this unique algal species, and hope that you all can help.

If you have an area that is affected, or know of one close to you and you would like to get involved, we would like to send you a sampling kit and return label free of charge. Depending on your level of curiosity, we can send you back some images of your sample under the microscope!

Please send me a message if you are able to help and we can give you more details. Thank you!

-James Lab, University of Michigan
