When to expect ruby-crowned kinglets in California

Ruby-crowned Kinglets are summer residents in California, arriving shortly before nesting begins in April and leaving after the young are independent.

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

Nesting in California

Across California, ruby-crowned kinglets typically nest from April–July. Plan around that window: March for setup, July for clean-out.

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

Ruby-crowned Kinglets 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 July.
