Female zebra finches don't learn to sing. However, a new study shows that their supposedly rudimentary song system is more active than thought when it comes to producing innate calls but is driven by different neurons than in males. 🧪Scientific publication: dx.doi.org/10.1111/ejn....

Meta-analysis questions assumptions about egg hormones
Do maternal hormones in bird eggs influence reproductive success? A new study shows surprisingly small effects. Dr Alfredo Sánchez-Tójar explains why previous assumptions need to be questioned.

Elevating local perspectives for equity in ecological research
High-profile studies conducted in Global South (GS) countries with few, or no GS authors are published frequently, underrepresenting GS researchers in local high-impact publications. Here, we reiterate the importance of conducting equitable research, valuing GS researchers as equal contributors, and propose pathways to decolonize science.

Though we didn't find clear evidence for a relationship between egg hormones and fitness proxies, this does NOT mean hormones are unimportant The high heterogeneity found suggests context dependency (meta-analyses are rarely conclusive!) 📢 We need more research! 👇 📰 doi.org/10.1111/ele....

A single gene underlies male mating morphs in ruff sandpipers, a new Science study finds. The results show how evolutionary changes in a single gene's structure, sequence, and regulation can drive significant diversity within a single species. Learn more in our new issue: scim.ag/4arzNmU
A breeding ruff male (Calidris pugnax) in alert posture scans the breeding area for mating opportunities at Liminka Bay, Finland. Ruff males deploy one of three mating tactics that differ in aggressive and courtship behaviors. Differences in aggression between tactics are tied to concentrations of circulating androgens, which are modulated by the actions of a single gene.
