Wyoming. Journal of Field Ornithology
Woodpeckerswere studiedin the Medicine BowNational Forestof southcentral Wyomingduring1991and1992toidentifyhabitatsusedforforagingandnesting.A key componentof thisstudywasto evaluatethe snag-retentiopnolicyof the forest.Thirty of the 33 nestsof woodpeckerswere in aspentrees.Woodpeckersnestedin aspentreeswith an averagedbh of 26.7 cm (range18-45 cm). This diameterwaslargerthan the meandbh of availableaspen,11.8cm,or snags9,.0cm.The majorityoftheaspenstandsusedfor nesting were comprisedof large trees (>20 cm dbh). Woodpeckerswere observedforagingin all foresttypes,but spruce-firforestwasusedfor foragingmore frequentlythan it occurredin the studysites.Snagswereseldomusedfor nestingor foragingbecausetheywereoften smallerthan 18 cm dbh and in open clear cuts.Larger snagsat the edge of clear cutsor in the forestwouldin all likelihoodenhancewoodpeckernestingand foragingsites.
