Abstract

Spatial autocorrelations in the territories of four marshland-nesting passerines (Sedge Warbler Acrocephalus schoenobaenus, Reed Warbler A. scirpaceus, Reed Bunting Emberiza schoenidus and Savi's Warbler Locustella luscinioides) were demonstrated by correlograms computed by Moran's I coefficient. The data set was based upon territory mapping of breeding birds in Kis-Balaton Nature Reserve (W Hungary). For the Sedge Warbler seven consecutive line transect censuses were also evaluated. Except for the first two transect censuses, which were carried out at the beginning of the breeding season, autocorrelation analysis of the line transect censuses revealed similar patterns as the more accurate, but more time-consuming, territory mapping. Spatial autocorrelation analysis of transect data revealed the main features of the autocorrelation structure, the high value at any of the first three lags, but no . autocorrelation at lag 4 or 5. I conclude, that the line transect censuses provide adequate data to detect spatial relationships in territorial birds.
