Abstract
Long-term dynamics of space use in the House Sparrow Passer domesticus in two mountain villages of the Tyrol (Austria). From 1982 to 2000 we monitored breeding populations, small-scale dynamics of habitat use and nest site (territory) distributions of the House Sparrow in two neighbouring mountain villages (about 20 resp. 30 ha area) in the Tyrolean Alps near Innsbruck. In addition, relevant village structures (e.g., character and number of buildings, number and distribution of trees and hedges) and their changes over time were recorded on very small (<10 m2) scales in 1982, 1991 and 2000 and analysed using GIS tools. About 40 % of the village area showed pronounced changes in land use and vegetation cover in the course of 18 years. The number of House Sparrows decreased by about 50 % from 1982 to 1991 in both villages and did not recover until 2000. The overall decrease and shifts in density centres within the village areas were most strongly linked to a nearly five-fold increase in tree densities during the investigation period and to the patterns of tree distribution within the villages. Moreover, House Sparrows mostly chose older buildings for nesting and we speculate that new ways of constructing houses and especially roofs are also responsible for the decrease and high dynamic of space use of the House Sparrow.
