It mainly inhabits in coniferous forest, mixed coniferous and broad-leaved forest, broad-leaved forest and forest edge shrub, and nests under fallen trees or trees and branches. Like to eat poplar, birch buds and inflorescences, but also eat pine seeds, acorns, hazelnuts and grass seeds.

Botany

There are 6 national (grade II) key protected plants, including Pinus koraiensis (< ipinus koraiensis < / isieb. Et Zucc), Fraxinus mandshurica (< ifrax
