When to expect ospreys in California

Ospreys live in California all year. Wet, mild winters are the green season — the busiest time at coastal feeders as sparrows and hummingbirds settle in. That makes the cold months the time your yard matters most to them.

Mediterranean along the coast and Central Valley, alpine in the Sierra Nevada, and desert in the southeast.

Nesting in California

Across California, ospreys typically nest from February–June. Plan around that window: January for setup, June for clean-out.

Dry summers with little rain from May to October; water and summer-blooming natives matter more than extra seed.

Ospreys don't use nest boxes. Keep dense native shrubs and trees such as chokecherry, ponderosa pine, rabbitbrush for nest sites.
Delay heavy pruning of shrubs until after June.
