Abstract:
The paper presents selected parameters such as the number of eggs, egg size, number of fledglings and nesting success of Jackdaw "Corvus monedula" in nesting boxes. In February 2005, 35 nest boxes were hung on trees in a park in Sulechow, a town in Western Poland. Observations were conducted over the period 2005-2009. In each of the years the boxes were inhabited by 8, 15, 22, 11 and 6 pairs of Jackdaws, respectively. ; In the first three years the number of boxes occupied increased by 20% per year (maximum 62.9%), then dropped in the following two years to 17.1%. The number of eggs ranged from 2-6 with the average 4.8. The average egg length was 34.4 mm, width 24.7 mm and volume 10.6 cm3. Nesting success in individual years ranged from 16.7% in 2009 to 60.0% in 2006. The average number of fledglings was 0.8 individuals, while for successful nests it was 2.3. ; The obtained reproduction parameters were similar (egg number) or lower (nest success, the number of fledges) in comparison to results obtained in other studies in Europe, including from Poland. The decrease in the number of boxes occupied in the study period was probably due to low nest success. ; The observed nest boxes in Sulechow, which were willingly occupied by Jackdaws, are a good solution in a time of a decline in natural breeding sites. However, they need to be properly located, well-manufactured and maintained, and - preferably - equipped with some kind of protection against predators.
