Abstract: 

The present study on clutch size and egg characteristics of the Common Babbler, Turdoides caudatus caudatus (Dumont) was conducted in district Jammu (J&K) during 2010-2011. A total of 32 clutches were studied. The mean clutch size was recorded to be 3.1 ± 0.65 varying from minimum 2 to maximum 4. The most common clutch size was 3 (56.3%). Eggs were turquoise blue in colour, smooth and spotless. The average length, breadth, weight, egg volume and egg shape index of 30 eggs was found to be 22.1 ± 1.03 mm (Min. 21 mm; Max. 24 mm), 16.1 ± 0.66 mm (Min. 15 mm; Max. 18 mm), 2.5 ± 0.14 gm (Min. 2.2 gm; Max. 2.7 gm), 2.93±0.30 cm3 (Min. 2.41 cm3 ; Max. 3.97 cm3) and 72.98 (Min. 62.5; Max. 80.95) respectively. A statistically significant positive correlation was found between egg breadth and egg volume as well as between egg length and egg volume and egg breadth and egg shape index whereas a strong negative correlation was registered between egg length and egg shape index. No significant correlations were found between egg length and egg breadth as well as between egg volume and egg shape index.
