  • Bird communities of intensively cultivated fields in North-eastern Slovenia
    Vogrin, Milan ; Vogrin, Nuša
    Species richness and density of bird communities on intensively cultivated acres in relation to habitat characteristics were studied on the basis of counts in 15 fields (5-69 ha) situated on Dravsko ... Polje (46o25'N, 15o45'E), North-eastern Slovenia. There were three groups of fields: those covered with wheat, sugar-beet and maize. On overage, ten bird species bred on intensive cultivated areas. Six of these occurred in all three field groups. The density of bird population ranged from 0 to 11.6 pairs/10 ha, overaging 2.93 pairs/10 ha. Only two species (Alauda arvensis and Saxicola torquata) were amongst the dominants in all three kinds of fields. The highest densities were on wheat fields but the differences among field categories were not significant (Kruskal-Wallis test). The number of species and bird population density did not dependent on the area of a particular field or not relative edge length
