“…Our results agree well with those of other studies of dispersal in this species (Nilsson 1982, Enoksson 1987, Matthysen 1987a, Matthysen andSchmidt 1987, Winkel 1989), i.e. natal dispersal involves long distances whereas after their first breeding season Nuthatches are extremaly sedentary.…”

Survival and population dynamics of Nuthatches Sitta europaea breeding in natural cavities in a primeval temperate forest. -Ornis Scand. 22: 143-154.Data on breeding densities of Nuthatch were collected in three types of mature tree stands in Bialowieza National Park, E Poland, during 1975-90. Detailed observations on breeding and survival were made during 1987-89. The highest densities occurred in swampy stands (max. 4.8 territories per 10 ha), they were 10-47% lower in oak-hornbeam stands, and in coniferous stands densities did not exceed 1.2 territories per 10 ha. Nuthatch numbers reached a low in 1979, then increased over fourfold to a maximum in 1990. In contrast to the situation in Scandinavia, Nuthatch numbers in spring were not significantly correlated with the severity of the preceding winter, though their numbers seemed to be influenced by autumn seed supply and availability of caterpillars in the preceding spring. Yearly survival rates were close to 50%. Winter survival equaled that in spring and summer, and was even higher in the unusually mild winter of 1989/90 which had a rich supply of hornbeam seeds. Egg-laying in BNP commenced between 5 April and 26 April in different years. Clutches usually contained 6-9 eggs. On average two thirds of the nesting attempts resulted in fledged young, though nesting success varied much between plots. Nest losses were among the highest reecorded in European populations. Nests containing young were destroyed two to four times as often as nests with eggs, suggesting that the losses were mainly due to predation.

“…Additionally, unlike mist-nets, a trap or a clapnet is not trapping the bird each time it enters because on non-trapping days the trap and clap-net areas are used as feeders). Therefore, the age bias obtained can be explained either because of an increase in experience with age per se 22,26,27 or because of the probability of mistnet-shyness increasing with number of contacts and therefore with age.…”

“…This could again be related to the greater experience of adults 26,27 which might perceive a lower predation risk of feeding at the trap because of its elevated position (see ref. 19).…”
