Roosting in various shelters allows saving energy, especially in winter, thus hole nesting birds, like tits, search for places suitable to spend cold nights. Because the environment probably does not provide enough shelters for all birds from a winter flock to roost, a competition for best sites, as nest boxes, probably occurs. Therefore, the aim of this study was to describe the pattern of using the nest boxes by birds for roosting during three consecutive winter seasons and to determine the structure of a group of roosting birds in relation to the winter flock. Tits were captured and marked; daily controls of nest boxes were performed to find out which of them the tits used for roosting and subsequently, birds entering these boxes were caught at night. Great tits Parus major were the most abundant species roosting in the studied boxes with proportion of blue tits Cyanistes caeruleus differed between years. Young individuals prevailed among the birds roosting in nest boxes. However the age and sex structure of great tits roosting in nest boxes was similar to that observed in winter flocks, which was in contrast to earlier studies that found that the males and older individuals, high in the social hierarchy of the flock, will take over these boxes. The size of winter flock differs strongly among winters, thus it is possible that the level of competition for these roosting sites also varies between the years.

Our aim was to determine dynamics in a population of tawny owls Strix aluco over 15-year period, in relation to year-to-year variation in environmental conditions. The research was carried out in a habitat mosaic of fields and forest in central Poland, over the 2004-2018 period. Numbers of pairs (territories) were established by the standard playback survey technique supplemented by searches for nest sites. The selected environmental factors studied in parallel were the acorn production, density changes in field and forest rodents, meteorological conditions in winter and density of martens (Martes spp.). At the start of the study period 20 nest boxes designed for tawny owls were placed out in the study area. This number was enlarged by additional 27 nest boxes placed in 2012. The number of owls in the area remained stable – in the range of 26-29 pairs, despite changes in nesting sites availability. However, moderate influence of rodent density and winter conditions on population abundance was detected. Also, peak in the rodent population coincided with greater clutch size and numbers of young owls reared. Densities of martens remained relatively stable throughout the study period, and there were no reported cases of these carnivores killing tawny owls, despite the former taking shelter in the owl-boxes.
