Abstract

We studied the territoriality of the Great Tit (Parus major) in winter, on the basis of spatial arrangement of roosting birds. The study was conducted in a Central Hungarian swamp from 1988 to 1990. We developed a simulation model to analyse the spatial pattern (uniform, clumped or random) of roosting birds based on nearest-neighbour distances. This technique compares the observed nearest-neighbour distances with the expected values from random arrangement of the individuals. The results showed that random spatial pattern of roosting individuals was common. There may be biological reasons which caused the failure to show winter territoriality in the Great Tit: (1) the variations in wintering strategies (floaters, residents), (2) possible alliance among individuals, and (3) no territoriality in winter at all.
