Abstract
A population of approx. 30 Whitethroats were studied during the breeding seasons in 1965 and 1967 to 1970 at Fagelsngsdalen near Lund in South Sweden (55'42'N, 13?20'E). Most territories were about 1 ha, a territory being the area within which all activities normally took place. For the habitat selection the following key factors were found: a) two or more conspicuous song posts, b) vegetation suitable for nestsite, and c) presence of singing Whitethroat males. In the beginning of the breeding season when the vegetation was low, the nests were built on the ground, but later above it. The location of the nests corresponded with the distribution of thorny bushes, nettles and the like.
