Upper Mississippi River National Wildlife & Fish Refuge We appreciate everyone's passion for wildlife and for the National Wildlife Refuge System. Webcams are amazing in that they allow us to witness and observe birds and animals in their natural habitat, which unfortunately also sometimes includes death. It is never easy to watch something struggle, especially a young bald eagle. The mission of the US Fish and Wildlife Service is to protect habitat for plants and animals that are going through all stages of life and death. This includes struggling to produce enough energy during the molting process. This bird eventually ran out of energy and ultimately perished, which isn't easy to watch, but happens quite often to wildlife - especially with younger birds and animals. While we do everything we can to protect our shared natural resources, we also allow for natural, ecological processes to play out, with minimal human intervention. Thank you for your concern and love for the Upper Mississippi River.
