When to expect ospreys in Utah
Ospreys are summer residents in Utah, arriving shortly before nesting begins in March and leaving after the young are independent.
Semi-arid to arid, with the Wasatch Range rising above the Great Basin and red-rock canyon country in the south.

Across Utah, ospreys typically nest from March–June. Plan around that window: February for setup, June for clean-out.
Hot, dry summers.
- Ospreys don't use nest boxes. Keep dense native shrubs and trees such as chokecherry, ponderosa pine, gambel oak for nest sites.
- Delay heavy pruning of shrubs until after June.
