- The bird stays mostly on the ground and takes a flight when surprised.
- They dig up burrows in the snow to stay warm.
- Ruffed grouses often emit a drumming sound through wing flapping while defending own territories.
- Usually solitary, but these birds often create groups to have foods together
Mating & Reproduction
The courtship starts with the male grouse looking for potential female partners through drumming a “thump thump” sound. After this, the female starts building bowl-shaped nests at the tree base or rock. Females lay cream white to cinnamon colored 9-14 eggs each sizing 1.5-1.6 in. They are incubated for 23-24 days.
Young grouses have a cluster of black feathers in a triangular shape around their ears. Within 24 hours of hatching, they become capable of walking and feeding all by themselves.
