Fish and Game Department officials are asking the public to report sightings of wild turkey hens and their young turkeys.
The annual survey continues through Aug. 31.
Wildlife biologists said participants in 2015 reported a record 2,202 broods. The average hatch date last year was June 19.
Officials said they are particularly interested in getting reports from the northernmost counties of Coos, Carroll and Grafton.
Biologists said young turkeys are particularly sensitive to cool weather and rain. Those factors affect their health and the supply of insects on which the young turkeys feed.
Fish and Game Department wildlife programs supervisor Kent Gustafson said the survey helps biologists gather information on turkey productivity, distribution, brood survival and nesting and hatching times.
