• Resumen

  • The egg size of the Blackbird Turdus merula is compared between an urban and a rural habitat in Slovenia. In general, egg dimensions were similar to other data from the literature. There was no significant variation in egg length, breadth or volume between urban and rural habitats. However, egg shape differed significantly between localities: in rural habitat, egg length and breadth tended to increase together, while this was not the tendency for urban habitat. In addition, egg shape was negatively and significantly correlated with egg length in the urban area but not in the rural area.
