Female Northern House Wren Testosterone and Aggression Data

A 45.4 KB dataset from figshare examines circulating testosterone concentrations in female northern house wrens. Author Cara Krieg collected data comparing hormone levels after simulated territorial intrusions and across different breeding stages. The dataset includes files in R, CSV, and TXT formats and was last updated on May 30, 2026.

Use Cases

• Test the hypothesis that testosterone responds to social challenge based on simulated territorial intrusion experiments.
• Compare aggressive intensity levels among females based on their response to simulated territorial intrusions.
• Analyze testosterone concentration variation across breeding stages when competition is most common.

Strengths

• Data is openly licensed under CC-BY-4.0.
• The dataset is part of a larger, related study, providing context.
• Includes data from multiple experimental conditions (STI, playback capture, breeding stages).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 45.4 KB size indicates a very limited scope and sample size.
