Bed-sites of radio-collared adult roe deer Capreolus capreolus were identified during summer 1994 in the Lier valley, southern Norway. Site characteristics were measured at the bed-site and at a randomly chosen site 50 m away. Roe deer preferred to bed down below dense canopy cover, but showed no preference for bedding close to tree trunks. The availability of herbs was higher at bed-sites than at random sites, and higher at bed-sites used by females than at bed-sites used by males. On warm days the abundance of herbs at bed-sites was lower than on cold days, indicating movement away from feeding sites. During warm days roe deer selected bed-sites with humid substrates, probably to increase heat loss by conduction. Bed-sites were well concealed.
