The monitoring of population state of White Stork (Ciconia ciconia L.) in the National Nature Park "Pyriatynskyi" and surrounding area was carried out in 2014–2019. The number of nests in the area was counted and the nest site selection were investigated. A breeding success analysis was also conducted. There were from 86 to 102 nests occupied by storks observed for a six-year study period. The mean number of fledglings in relation to all nest occupying breeding pairs (JZa) was 2,43 ± 0,04 (n = 570), and in relation to breeding pairs with nestlings (JZm) was 2,75 ± 0,04 (n = 502). The percentage of unsuccessful pairs was 10,07 % (%HPo). In different years, breeding success (the proportion of successful pairs with fledglings) ranged from 78,43 % in 2017 to 98,94 % in 2015. The majority of pairs fledged 2 (34,93 %) or 3 (36,92 %) young, that makes 71,85% of broods for total. Broods of 5 nestlings, which is the maximum value for the study area, are rare and registered not every year. Only 4,44% of the total number of such nests was identified for six years. During 2015–2016 storks hatched a smaller number of nestlings, but far more successfully fledged them than in the previous year 2014 and subsequent 2018–2019 years. The year 2017 became the most unfavorable for stork breeding in the region of the park – birds raised the smallest number of fledglings, and the proportion of unsuccessful pairs was the largest for the years of observation. All found nests of a White Stork are located singly within the boundaries of settlements. The preferred nest site is on poles (69,29 % of the total nest number), other types of placement are less common (trees, buildings of various types, water towers and artificial nests). 10 or more nests of storks were recorded in the villages Deimanivka, Povstyn, Antonivka, Usivka and Kaplyntsi located in the floodplain of the Udai river. The average density of nests per settlement was 1,7 ± 0,3 km2.

The Magpie Pica pica occurs all over open agricultural areas in Poland, especially near human settlements (particularly in western Poland). The aim of this study was to estimate the size of the local Magpie population and characterize, in detail, nest site selection in a medium size city Górzów Wlkp. in the XXI century. For this study, the whole city was divided into a total of 114 squares of 1 × 1 km. Data were collected in spring 2014. A total of 474 Magpie pairs were recorded. The average density was 5.5 pairs/km2 (min = 0, max = 22 nests/square), in the non-urbanized habitat type—3.7 p/km2, and in the urbanized habitat type—13.5 p/km2. Magpie nests were found most often on Spruces Picea sp. and Poplars Populus sp. The mean height of the nest site was 11.5 m, while the mean height of trees used for nesting was 13.4 m. The type of tree arrangement most frequently used for nesting was tree rows (26.3%), followed by single trees (24.6%) and clusters of 4–10 trees (20.1%). The results for the Magpie’s environmental preferences do not differ from the general patterns described earlier. The study shows that magpies can adapt to changing urbanization factors, and changes in the choice of conifers help the species to adapt to highly anthropogenic habitats.

AbstractChanges in the spring arrival dates of migrant birds have been reported from a range of locations and many authors have focused on long-term trends and their relationship to temperature and other climatic events. Perhaps more importantly, changed arrival dates may have consequences for the breeding dates of birds which strongly influence breeding success. In this paper we take the opportunity provided by a monitoring scheme of the white stork (Ciconia ciconia) to examine several features of the timing of arrival and breeding in relation to chick production in Slovakia during the period 1978–2002. First arrival dates ranged from 5th March to 30th April, and hatching dates varied between 26th April and 8th July. Generally, early arriving pairs started breeding earlier and a shorter interval between the arrival of the first partner and breeding, expressed here as hatching date, resulted in higher breeding success.
