Resumen:
The South American Hornero (Furnarius rufus)
is a suboscine bird widely known for its mud-made, oven-looking nest.
Beyond their architectural skills, the male and female Horneros sing in
highly structured duets. The analysis of field recordings reported in
this work reveals that as the male increases the note production rate
the female responds by switching to different locking states: the ones
predicted by the theory of nonlinear forced oscillators. This gives the
duet a most appealing rhythm, and unveils the nonlinear nature of the
underlying brain activity needed to generate the song.
