Z. Dolenec
Abstract
This study was conducted in Krapina river valley in north-western Croatia during 2004 – 2005. The mean nest density of the hooded crow on the research was 3.73 nest/km². The mean clutch size was 4.34 and egg size (volume) was 17.63 cm³. Mean egg length (2004 – 2005) was 41.11 mm, breadth 28.97 mm and egg shape index 1.42. The positive correlation between length and breadth was (p<0.05). There was no significant correlation between clutch size and the volume of eggs (p>0.05).
