Research data investigating female and male plumage ornamentation in relation to sociosexual selection pressures in Tyranni passerines. The dataset, authored by Gabriel Macedo and hosted by Harvard Dataverse, was last updated on June 10, 2026. It likely contains measurements and classifications used to test associations with territoriality, mating system, parental care, nest type, migratory behavior, and climatic seasonality.
Use Cases
- Modeling associations between plumage ornamentation and sociosexual selection pressures like territoriality and mating system.
- Analyzing the evolution of sexual dichromatism based on factors such as parental care and migratory behavior.
- Testing hypotheses about shared versus divergent selection pressures on female and male traits in bird species.
Strengths
- Data underpins a published study providing a framework for testing how sociosexual selection shapes female traits.
- Focus on the understudied topic of female ornamentation evolution in a specific avian clade (Tyranni).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
Provenance
- Source
- Harvard Dataverse
- Collection Method
- Likely compiled from ornithological literature, museum specimens, or field observations for the associated research study.
