Correlation matrix

This graph shows the correlation between the parameters used to define the acoustic space. Parameters in which the absolute correlation was higher than 0.95 were removed. Note that random forest is very robust to colinearity.

Confusion matrix

This is the accuracy of the random forest model at correctly clasifying call types on pre-defined categories based on spectrograph similarity for human observers.

Variable importance

The relative contribution of each acoustic parameter to the random forest predictive model.Long story short: cross-correlation dereived parameters are the most important ones.

Random Forest acoustic space (based on bootstrap MDS)

Acoustic space defined by the 2 dimensions of a boostrap multidimensional scale analysis on the random forest proximity (see here for details).

Change in acoustic space area through time

These graphs show, for each individual, the cumulative (pink line) and relative (blue line) change in the area of its acoustic space (convex hull) as new calls are included. Relative change was defined as the change in acoustic space for the last 10 calls at any time. The calls were added in chronological order (as their were produced) and the period in which they occured is shown by the background color. If social group stability plays a role in acoustic “drift”, then a bump in the acoustic space would be expected at the start of the “post” period in birds in novel social groups.

Acoustic space plots with spectros

These plots show the acoustic space covered by each individual in 2 ways: - Using dots to show the position of each of its calls in the acoustic space - Using kernels to display the density of calls in acoustic space regions

Both plot types are shown consecutively for each individual for comparison.
