nr 1

Characteristics of Great Spotted Woodpecker roosting holes are compared with those used for breeding. Neither postbreeding nor winter roosting holes differed from woodpecker nests with respect to tree species, condition, girth at breast height, cavity height or cavity direction. However, behavioural observations suggested that particular holes might be selected, probably in connection with microclimate condition and predator avoidance.

nr 1

Roost utilisation by Rhinolophus ferrumequinum (Schreber, 1774) was investigated between 1984 and 1998 in north-eastern Hungary. Exploration of summer and winter roosts, monitoring and bat-banding were implemented to find movements between the colonies. Data on roost utilisation by this species in south-eastern Slovakia, collected in a similar way, were included for comparison. Twenty-two marked bats were recaptured. The studied bats created nursery colonies in Hungarian churches and moved to Slovakian mines and caves to hibernate in winter. The population used two main hibernacula, two large nursery roosts and one temporary roost but several other roosts were also visited. The area occupied by the population was 5180 km . R. ferrumequinum living in SE Slovakia and NE Hungary formed probably a separate population on the northern edge of the species range. This population is a part of the metapopulation of the species.
