This study examines infanticide in sociable weavers and finds no direct reproductive benefits, suggesting indirect fitness benefits may drive the behavior.

Across eleven years and more than 1,800 sociable weavers, black bib size grew with age but did not predict dominance; age predicted dominance in males only.

This study reviews and analyzes 57 studies on egg hormones in wild birds, finding near-zero overall effects on maternal and offspring fitness but high heterogeneity.

This paper conducts a meta-analysis of 371 effect sizes from 75 studies on acoustic adaptation hypothesis, finding no consistent support for vegetation structure affecting acoustic signaling across terrestrial vertebrates.
