Relation between actual and predicted male feeding rates. Using the support vector machine algorithm we were able to reliably predict male feeding rates on the basis of the combination of four different song features (average shortest path length, buzz, whistle and trill repertoire size). This is indicated by the strong correlation of the actual feeding rates observed in the field and the rates predicted by the algorithm (calculation based on 20 males). For statistics see text
