Vocal development and patterns of vocal variation inform conservation of a critically enda

26 acoustic parameters were measured from contact calls of adult and nestling great green macaws (Ara ambiguus). The dataset, authored by Alexander Allison and last updated in May 2026, contains recordings from one wild, one captive, and one reintroduced population in Costa Rica to investigate vocal variation for conservation insights.

Use Cases

• Assessing vocal similarity among populations based on spectrographic cross-correlation.
• Modeling how nestling social environments shape dialect formation based on call variation.
• Informing reintroduction strategies by evaluating potential communication barriers between released and wild birds.
• Analyzing the role of selective attrition and vocal convergence in adult call structure.

Strengths

• Includes data from three distinct population types (wild, captive, reintroduced) for comparative analysis.
• Analyzes 26 acoustic parameters per call for detailed spectrographic characterization.
• Examines both adult and nestling vocalizations, offering insights into developmental stages.
• Released under a permissive CC0-1.0 license for unrestricted reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset size is listed as 0.0 B, indicating a very limited scope or potential metadata issue.
