Melodiewahrnehmung und Wiedergabe beim Gimpel: Untersuchungen an liederpfeifenden und Kanariengesang imitierenden Gimpeln (Pyrrhula pyrrhula)

摘要

The analysis of the songs of bullfinches that as juveniles had learned a human melody or song parts of a canary give insights into the perceptive faculties and into the learned coordination between the muscles of the vocal organ, the syrinx — responsible for the pitch of the note — and the respiratory apparatus, which determines the different durations of consecutive notes. Our study is focussed on determining whether the bullfinch can learn the temporal pattern of a song, and if it perceives melodies. Does a bird perceive the series of notes in the human melody as a series of unrelated elements or is its perception more humanoid, for example by determining the relative proportion of ascending and descending intervals?
