Temporarily Closed

*Before calling the refuge for updates, please review this section of our website or our social media pages. Any new information will be posted here and to our Facebook  and Instagram promptly. Areas are subject to closure without notice. Please use extreme caution when driving the refuges, as flooding can occur without warning and road shoulders are soft and will not support your vehicle.

Did you find an injured or abandoned animal or bird?

The Refuge Complex does not rescue, rehabilitate or accept injured or orphaned animals.

Please visit California Department of Fish and Wildlife's Native Wildlife Rehabilitation webpage for what to do and frequently asked questions, noting the following (copied directly from CDFW's webpage):

  • DO NOT intervene without proper guidance from a trained professional (i.e., capture, handle, confine, feed/water).
  • 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.
