Ruffed grouse consumption and detoxification of evergreen leaves

Article Abstract:

The toxic evergreen leaves of the mountain laurel and Christmas hollyfern are commonly eaten during winter by ruffed grouse in the southeastern US. The leaves are extremely abundant but rarely make up more than half of the grouse's diet. A study of captive ruffed grouse shows that they seem to be unable to survive on a sole diet of evergreen leaves, but are able to consume large amounts of evergreen leaves because they can conjugate toxins. Evergreen plants are an important food for grouse, especially during winter.

Ruffed grouse brood habitat use in mixed softwood-hardwood Nordic-temperature forests, Quebec, Canada

Article Abstract:

Habitat use by ruffed grouse during the brood-rearing period is assessed by comparing characteristics of tree, shrub, and ground layers at ruffed grouse brood, and random locations in forests of Quebec, Canada. Females with broods are found to use specific mixed and regenerated clearcut stands, and grouse locations are found to have higher lateral obstruction, higher small-stem density and are closer to roads and trails than random locations.
