The White-tailed Ptarmigan (<em>Lagopus leucurus</em>) is one of the few socially monogamous species within the highly polygynous grouse subfamily (Tetraoninae). I found White-tailed Ptarmigan in Glacier National Park, Montana, to be nearly genetically monogamous. Of 58 chicks with putative fathers identified, three were the result of extra-pair copulations (5%). Three of 18 clutches (17%) contained extra-pair offspring. I suggest that White-tailedPtarmigan males are able to guard their females effectively from extra-paircopulations because of high visibility in their habitat and their ability to forage alongside their mate. The three extra-pair offspring were sired by unknown males.
