Sažetak
This paper presents egg-characteristics (only first clutches with five
eggs included) and the deviation of the final egg from mean referred
here as %D-value in Song Thrush Turdus philomelos in deciduous forests,
parks and traditional orchards in northwestern Croatia. Study comprised
the period from 2021 to 2024. Egg length averaged 27.74 (±1.33)
mm, egg breadth 20.51(±0.76) mm, egg volume 5856.85 (±528.41) mm³
and egg shape (elongation) index 1.38 (±0.05). According to the value
of %D = 5.6, the Song Thrush adopted a “brood survival strategy” to
ensure that more offspring could survive. The results presented in this
paper contain first oological data reported on Song Thrush in Croatia.
