Quick Answer
Ruffed Grouse can find temporary safety in thickets from predators such as coyotes and bobcats, but these thicket refuges often have limited protection, and the birds' safety is not guaranteed.
Limited Thicket Protection
Ruffed Grouse often rely on dense thickets of shrubs like alder, birch, and aspen to escape predators. However, these thicket refuges can be vulnerable to heavy snowfall, strong winds, and prolonged periods of wet weather, which can weaken the vegetation and provide a clearer path for predators. In such cases, the thicket may not offer sufficient protection, and the grouse may be forced to seek alternative shelter.
Thicket Characteristics for Grouse Safety
Effective thicket refuges for Ruffed Grouse typically have a dense canopy of vegetation that is at least 3-4 feet (0.9-1.2 meters) in height, with a mix of deciduous and evergreen species. The thicket should also have a relatively small entrance diameter, around 1-2 feet (0.3-0.6 meters), to prevent larger predators from entering. Additionally, the thicket’s understory should be relatively free of deadfall and other obstacles, allowing the grouse to move freely within the thicket.
Grouse Thicket Behavior
When using thicket refuges, Ruffed Grouse typically remain motionless, relying on camouflage to avoid detection by predators. The birds may also alter their vocalizations to avoid attracting attention or use a different location within the thicket to escape detection. In some cases, the grouse may even temporarily occupy a thicket that is being actively used by a predator, in an attempt to avoid detection.
