BIOECOLOGICAL PROPERTIES OF PASSER DOMESTICUS

Abstract

This study briefly covers the bioecology of the house sparrow (Passer
domesticus L.), habitat, feeding spectrum, reproduction phenology, and adaptation
strategies to anthropogenic landscapes. The analysis, conducted in the context of
urban and rural biotopes, shows that the sparrow, as a popular “synanthropic”
species, exhibits trophic behavior closely related to waste, livestock infrastructure,
and arable land. During the breeding season, the pairs place their burrows in cracks
in buildings, under roofs, and tree hollows; the proportion of insects in the chicks'
diet increases, which can reduce pest pressure to a certain extent during the
growing season. Also, in areas with high population density, there is a possibility
of conflicts related to hygiene, noise, and competition factors. The results indicate
the need for balanced management of the functional role of the house sparrow in
agro- and urban ecosystems.
