The Mean

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.

Selection Of

The selection of breeding habitat is of prime importance for individual fitness. Among birds, natural selection should favour the ability to recognize and select habitat suitable for nesting and rearing chicks. This study compares the characteristics of Sabine's Gull, Xema sabini (Sabine, 1819), nest sites with random points across a coastal tundra environment on Southampton Island, Nunavut, Canada. The availability of terrestrial invertebrate prey was also examined among habitats. Sabine's Gull nests were nonrandomly distributed in relation to vegetation, substrate, and proximity to water. Gulls nested within approximately 1 km of the coastline and selected sites with the greatest proportions of moss and standing water (i.e., they nested close to the edge of small freshwater ponds near shore). However, there were no detectable differences in characteristics between successful and unsuccessful nests within preferred habitat. The dynamics of terrestrial invertebrate prey communities varied between years, but the volume of invertebrates in Sabine's Gull nesting habitat was intermediate between the most productive habitats and the least productive habitats in both years. However, nest-site selection in Sabine's Gulls may also be influenced by the availability of aquatic invertebrates (not examined in this study) and their proximity to the marine coastline, where chicks are taken to be reared.

Habitat Parameters

Nest-site selection and breeding success of the Grey Hypocolius ( Hypocolius ampelinus) were surveyed in relation to plant structure in 2010 and 2011 in southwestern Iran. Microhabitat parameters such as Ziziphus nummularia as the main shrubs used for nesting, were measured in 20 × 20 m plots around the nest and compared with random plots. There were no best clear model for predicting the nest-site selection, however, plant variables especially the canopy cover and diameter of the Z. nummularia, were the most important determinant for nest-site selection ( wi = 0.5). Grey Hypocolius preferred areas with a higher density of Z. nummularia than other available habitats (28.21 vs 1.2 of cover). There was no strong predictor for breeding success, the best models incorporated either Z. nummularia density or diameter (with model weights of 0.25 and 0.17, respectively). Nests of Grey Hypocolius had a higher chance of success at higher densities of Z. nummularia in nesting plots. We found that a higher density of Z. nummularia improved both the probability of nest-site selection and the breeding success of Grey Hypocolius. Shrubs with greater diameters were more likely to be selected for nesting, but had lower breeding success. To identify the key reasons of nests being successful, more habitat parameters should be monitored. The majority of failure in breeding occurred during the incubation stage (52%).
