Method synopsis

Species diversity technique adapted for song analysis that standardizes sampling effort across individuals to provide comparable repertoire size estimates using rarefaction curves.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Can rarefaction be used to estimate song repertoire size in birds? (2011), Current Zoology. Implementations in other papers (listed below) may differ.

1. Apply behavioral accumulation curve analysis
   Fit counts of first 50-, 100-, and 150-syllables to behavioral accumulation curve using quadratic equation P_syls = T_syls/(a/b) where P_syls is portion of syllables from individual sung, T_syls is total syllables sung, a is intercept, b is slope. Average results across data sets and calculate 95% confidence intervals.
   Quantities: First 50, 100, 150 syllables fitted to quadratic equations for each data setDuration: Not specifiedConditions: Used same source recordings as other methods
   Equipment: Quadratic equation fitting analysis
