Song Syntax in Bengalese Finches: Proximate and Ultimate Analyses

open access: yesSong Syntax in Bengalese Finches: Proximate and Ultimate Analyses
Bengalese finch song has a unique type of complexity. We analyzed the syntactical rules underlying it by statistical methods and found that the songs of these birds could be expressed as finite state syntax. In general, two to five song notes are arranged in fixed order to form "chunks" and several chunks are arranged with probabilistic rules into ...

Context-dependent song amplitude control in Bengalese finches

open access: yesContext-dependent song amplitude control in Bengalese finches
Estrildid finches have two song types: directed (courtship) and undirected (solo). These are acoustically identical and differ only in social context. Recent studies have shown that undirected singing is accompanied by strong activation of the basal ganglia pathway, whereas directed singing is not, which suggests a different degree of feedback control ...
