Abstrakt		In 1995, breeding by the White-backed Woodprecker Dendrocopos leucotos was confirmed in the Gorjanci Mountains. In the last few decades this bird has been known to breed, as far as Slovene territory is concerned, only at Kočevski Rog. The Gorjanci individuals had bars over their white rump and the lower part of the back, which is one of the features of the subspecies D.l.lilfordi. The nest was situated in Trdinov vrh Nature Reserve, namely in a beech forest at an altitude of about 1100 m a.s.l. It was made in a dry upright stump of a beech some 15 m above the ground. On May 26th the young were already peeping through the nest hole. After the feeding, the male stood still for a few moments by the entrance to the nest, then drummed upon the dry wood and flew away. During its 5 visit of the nest it drummed three times. The young left the nest by May 29th. The spring of 1996 was cold and snowy with belated vegetation. On June 4th the White-backed Woodpeckers were recorded at two localities within the Gorjanci Mountains. In the first case the young had not been fledged yet, while in the second the young had not been even hatched. During the search for food, dimorphism was noted. The male looked for it on trunks and thicker boughs, the female preferably on thinner branches.
