Sex-Specific Apparent Survival Estimates for 92 North American Bird Species

563,414 bird banding records were used to estimate sex-specific apparent survival for 92 species across 17 families and 2 orders. The data, authored by Joanna X. Wu, shows female adult birds had an average apparent survival of 0.479, which is 12.4% lower than the male average of 0.538. The dataset was last updated on June 4, 2026.

Use Cases

• Modeling sex-specific survival rates based on banding records mentioned in the description
• Analyzing the relationship between movement costs and survival differences between sexes
• Investigating the role of social dominance in male-biased survival across species
• Comparative demographic studies across 17 bird families and 2 orders

Strengths

• Based on a large sample of 563,414 individual bird banding records
• Covers a broad taxonomic scope of 92 species across 17 families and 2 orders
• Provides specific, quantified survival estimates (e.g., female: 0.479 ± 0.009 SE, male: 0.538 ± 0.008 SE)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic or temporal bias inherent to the banding record sources
