Sažetak
During May-July from 1989-1991 I studied Blackcap nests in the Hrvatsko Zagorje region. I examined the lowlands along the Krapina River and particularly the area belonging to the village of Mokrice in the Hrvatsko Zagorje. The most dominant structure of the nest is of vegetable origin (79.7%), then of animal origin (19, 9%) and the least represented (0.4) is of man made products. The altitude of the nests which I found was from 30 cm to 190 cm, mostly 40-70 cm above ground. On average I found 4.8 (2 to 6) eggs per nest. The average length of an egg was 19.28 mm, the average width 14.24 mm. The average mass of a fresh laid egg was 2.03 grams, of the egg shell 0.13 grams, the calculated egg volume was 2139.16 mm3, and the egg index 1.34.
