- DO NOT drop off wild animals at a location, unless instructed to do so.
Bald Eagle Nest - Sacramento NWR
Updated April 30, 2026: We have a sad update to share regarding the eaglets from the bald eagle nest along the auto tour route at Sacramento National Wildlife Refuge.Despite a promising start, both eaglets fell from the nest. One was found deceased, while the other was recovered alive, but in poor condition. The surviving eaglet was transported to a raptor rehabilitation facility in an effort to save it but did not survive.
This difficult moment serves as a reminder of the natural cycle of life. Nature can be both beautiful and harsh at the same time. While these eaglets were loved by many given their proximity to publicly accessible areas, multiple nesting bald eagle pairs continue to be supported across the refuges and wildlife management areas of the Sacramento National Wildlife Refuge Complex. We appreciate everyone’s care and support for bald eagles and their habitats.

Our Organization
National Wildlife Refuge System Improvement Act of 1997:The NWRS Improvement Act defines a unifying mission for all refuges, including a process for determining compatible uses on refuges, and requiring that each refuge be managed according to a CCP. The NWRS Improvement Act expressly states that wildlife conservation is the priority of System lands and that the Secretary shall ensure that the biological integrity, diversity, and environmental health of refuge lands are maintained. Each refuge must be managed to fulfill the specific purposes for which the refuge was established and the System mission. The first priority of each refuge is to conserve, manage, and if needed, restore fish and wildlife populations and habitats according to its purpose.
Our Species
