We studied hazel grouse in the field at Changbai mountains in Jilin province from 1989-1993. The spring population density varied from 2.2 - 26.1 bird/square m in different habitats in 1991-92, having decreased sharply in the past 20 years. Eight hazel grouse (3 males and 5 females) were studied during April to August. In spring, monthly home range areas of males varied from 10.7 to 152.8 ha, bigger than those of females. In July and early August, a male grouse moved into a small area (18.6 ha), where deep blue honeysuckle and oriental strawberry were abundant. Home ranges of females during late incubation were 0.34 - 0.63 ha. One female led her brood up to 1.7 km from her nest over a 40-day period. When the chicks left her in mid-August, the hen went back to her mating territory. Sand-bathing was an important activity in summer, particularly on ginseng farms. Roosting and mating behaviour were also studied in spring and winter
