Abstract
The offspring sex ratios and breeding success in a population of the Great Tit, Parus major, in Antalya, southern Turkey, were determined. Feathers were collected from nestlings, un-hatched eggs and dead nestlings, and the sex was identified through CHD genes by amplifying P8 and P2 primers. The primary sex ratio (at conception) was 54% male and 46% female, the secondary sex ratio (at hatchling) was 52% male and 48% female, and the tertiary sex ratio (at fledging) was 53% male and 47% female. The predominance of males was statistically not significant (p>0.05) in all three phases. Hatchling success was found to be 87.3% in males and 100% in females; fledging success 96.1% in males and 91.6% in females, and general breeding success 85% in males and 93% in females. The mean number of fledglings per pair was significantly higher in first broods (p<0.05). Approximately the same number of males and females (0.53/0.47) fledged, thus resulting in a balanced sex ratio that may imply stable population structures.
