Приведены сведения о гнездовой фауне птиц памятника природы регионального значения «Урочище "Буданова гора"» (Саратовская область, Россия). В течение 2011–2021 гг. обследованы два кластерных участка этой охраняемой территории: эрозионный останец с окружающими степными участками и овражно-балочная сеть из пяти оврагов. Выявлены преобладающие виды птиц, обобщены и актуализированы данные о редких видах, в том числе включенных в Красные книги Саратовской области и России: филине (Bubo bubo), сизоворонке (Coracias garrulus), обыкновенной горлице (Streptopelia turtur). Оценены изменения в составе гнездовой орнитофауны за 10 лет, а также проведено сравнение с более ранними данными, опубликованными в литературе. Наибольшее разнообразие птиц характерно для овражно-балочной сети второго кластерного участка, благодаря наличию здесь склерофильных видов, гнездящихся в обрывах: золотистой щурки (Merops apiaster), сизоворонки, каменки-плешанки (Oenanthe pleshanka), удода (Upupa epops).

Streptopelia Turtur

Summary Conservation measures providing food-rich habitats through agri-environment schemes (AES) have the potential to affect the demography and local abundance of species limited by food availability. The European Turtle Dove Streptopelia turtur is one of Europe’s fastest declining birds, with breeding season dietary changes coincident with a reduction in reproductive output suggesting food limitation during breeding. In this study we provided seed-rich habitats at six intervention sites over a 4-year period and tested for impacts of the intervention on breeding success, ranging behaviour and the local abundance of territorial turtle doves. Nesting success and chick biometrics were unrelated to the local availability of seed-rich habitat or to the proximity of intervention plots. Nestling weight was higher close to human habitation consistent with an influence of anthropogenic supplementary food provision. Small home ranges were associated with a high proportion of non-farmed habitats, while large home ranges were more likely to contain seed-rich habitat suggesting that breeding doves were willing to travel further to utilize such habitat where available. Extensively managed grassland and intervention plot fields were selected by foraging turtle doves. A slower temporal decline in the abundance of breeding males on intervention sites probably reflects enhanced habitat suitability during territory settlement. Refining techniques to deliver sources of sown, natural, and supplementary seed that are plentiful, accessible, and parasite-free is likely to be crucial for the conservation of turtle doves.
