馃 The hazel grouse (Tetrastes bonasia)
馃摎 Tetrastes Greek: tetra艒n hunting bird, -ast膿s creator
馃摎 bonasia the etymology is unclear, one of the assumptions is "bonum" good, "assum" roast (lat).
These wild chickens are slightly larger than a pigeon, but weigh about 500g.
The bird is secretive and inconspicuous, most likely due to the fact that it is an object of hunting. However, in spring or autumn you can hear their voices. Their voices are high whistling, I would even compare it with the squeal of the wheels of a car.
If in the forest you find something like this in the photo, then you should know that there are these birds in this forest, this is their droppings.
Birds are herbivores, eat greens, buds and flowers, and berries. In winter, food is more difficult, they eat frozen buds and catkins of birch, aspen and some other trees.
