When to expect ospreys in Montana

Ospreys are summer residents in Montana, arriving shortly before nesting begins in April and leaving after the young are independent.

Continental — Rocky Mountain forest in the west, semi-arid Great Plains in the east.

Nesting in Montana

Across Montana, ospreys typically nest from April–June. Plan around that window: March for setup, June for clean-out.

Warm, dry summers and a short growing season.

  • Ospreys don't use nest boxes. Keep dense native shrubs and trees such as bur oak, paper birch, chokecherry for nest sites.
  • Delay heavy pruning of shrubs until after June.
