Eastern OR Merriam's & Rio Grande
Oregon's spring turkey season typically opens April 15 statewide and runs through May 31, capturing peak breeding through post-breed.
Oregon Department of Fish and WildlifeOregon's wild turkey populations are concentrated in the eastern half of the state, with Rio Grande in the lower elevations and Merriam's in the higher country. Peak breeding lands late April through mid-May depending on elevation.
Phases are calendar approximations driven by photoperiod — year-to-year variation is small. Peak Breeding is the toughest phase for call-response hunting; Gobbling and Post-breed are the best.

Oregon Department of Fish and WildlifeMerriam's country runs across a wide latitude range, but elevation is the dominant variable. Lower-elevation valleys peak first in late April, with high-elevation timber not peaking until mid-to-late May. Plan zones for elevation, not just latitude.
Spring turkey breeding is triggered by photoperiod — increasing day length — which makes it remarkably consistent year to year within a given latitude band. Weather can shift gobbling intensity by a few days, but biological breeding timing barely moves. That's why a calendar built from photoperiod data is genuinely actionable for planning.

Always verify season dates and licensing requirements with the official agency before hunting. Season structures change year to year.
Statewide phases are a starting point. Bield: Hunt logs your own observations — toms heard, hens seen, locations, conditions — and turns multi-season data into patterns no generic calendar can match.
