Is bigger better? Direct fitness correlates of group size in a cooperatively breeding bird, the jungle babbler Kanika Rajput (23748390) Manjari Jain (22281027) Behavioural ecology Animal behaviour Evolutionary ecology argya striata dispersal coalition group augmentation reproductive success territory quality <p dir="ltr">Direct benefits of living in larger groups include access to higher-quality territories, reduced predation risk and better territory defence, thereby enhancing the survival probability of group members. Breeders benefit from a reduced provisioning load and higher reproductive success, whereas helpers may receive direct fitness benefits by forming dispersal coalitions with newly produced recruits, thereby enhancing their future reproductive success. We examined these predictions in a cooperatively breeding Palaeotropical bird, the jungle babbler, <i>Argya striata</i>, across 21 groups over 3 years, including both nonbreeding and breeding periods.</p> 2026-09-22T13:14:14Z Dataset Dataset 10.6084/m9.figshare.33945226.v1 https://figshare.com/articles/dataset/Is_bigger_better_Direct_fitness_correlates_of_group_size_in_a_cooperatively_breeding_bird_the_jungle_babbler/33945226 CC BY 4.0
