From: Power-law scaling of calling dynamics in zebra finches
The self-contained (female: “f-f”; male:“m-m”) and the reactive (female: “m-f”; male: “f-m”) callings exhibit power-law dynamics. (a) Schematic of calling events (t) and inter-event intervals (τ). (b) Calling interactions are described as a mixture of self-contained (“f-f”; “m-m”) and reactive (“m-f”; “f-m”) callings of male and female zebra finches. (c) The empirical cumulative distribution functions (eCDF, dotted line, dark blue) of the inter-event intervals (τ) were plotted in a log-log scale. Estimated power-law cumulative distribution function (Power-Law CDF, solid lines, light blue) were modeled by using the maximum likelihood method32. Estimated exponential cumulative distribution functions (Exp CDF, dashed lines, magenta) were modeled with corresponding average inter-event intervals (μ τ ). Data are shown from the female-male pair “a”. α: the exponent of a power-law distribution; P(τ): the cumulative distribution of the inter-event intervals; τ (s): the inter-event intervals in seconds. (for estimated parameters, see Supplementary Table S1).
