House Sparrows Passer domesticus and Tree Sparrows Passer montanus: Fine-Scale Distribution, Population Densities, and Habitat Selection in a Central European city

Popis výsledku v původním jazyce

In our study we investigated fine-scale distribution, population densities and habitat selection of both sparrow species within a 200 x 200 m squares in a medium sized city (České Budějovice, Czech Republic) during the breeding season. The total population density of House and Tree Sparrow was 11.7 and 2.8 individuals/10 ha; however the densities of both sparrow species markedly differed among various urban units. The highest density of House Sparrow was recorded in residential areas (33.3 ind./10 ha) and Tree Sparrows were mostly found in garden colonies (10.3 ind./10 ha). After removing spatial effects, we found that numbers of both sparrows were negatively correlated with area of artificial surfaces (e.g. pavements, streets, railway networks or parking spaces) and positively correlated with area of city green. Built-up area did not affect numbers of House Sparrow, but there was a slight negative relationship with Tree Sparrow numbers. However, maximum numbers per square for both spe
