Reported Sightings

Waterfowl in flightOver 300 species of birds and a diversity of animals have been recorded at the Sacramento National Wildlife Refuge Complex since 1937. We encourage visitors to report to us any sightings of rare, unusual, or unique animals on our refuges and the surrounding areas.

This list is updated approximately monthly between November and March. Many of the sightings and identification is performed by the public and can be subject to error. Remember that wildlife regularly move around the Sacramento Valley. Respect all wildlife laws, signs, and regulations. Please park in designated parking areas. National Wildlife Refuges are places where wildlife comes first! Postings are more regularly updated on our Facebook page.

A male Falcated Duck was identified at Colusa National Wildlife Refuge in 2011 but it returned again on December 2, 2012. This vagrant from Asia is sometimes seen in the Aleutian Islands of Alaska, but an extreme rarity for California. Birds seen in the USA are sometimes escapees from captivity but no determination has been made on this bird. This duck is in the teal family and is named for the male's long, falcated (sickle-shaped) tertials (wing feathers near the body) that overhang onto the tail. The last staff-confirmed sighting of the duck was around December 24, 2012.

Have you seen a Sacramento Valley Red Fox? Red foxes in the Sacramento Valley were thought to be non-native until genetic testing in 2005 by UC Davis revealed that these foxes were native and potentially in decline. In 2007, a website was set up for the public to report sightings of Sacramento Valley red foxes. Now, Master's Student Amy Brasch of Victoria University of Wellington is assessing: (1) how effective public input was on locating the foxes and (2) how the website can be improved for future conservation efforts. You are invited to share your opinions regarding red foxes and the fox sighting website in a brief 5-minute survey located on the fox sighting website:
