Movies S1 to S3

Movie s1
This file illustrates a type I male's "growl" vocalization in response to a type II male in front of his nest. A second type II male is also positioned outside the nest.

Movie s2
This file illustrates a type I male's "grunt" vocalization produced after expelling a type II male from his nest. The type II male adopts an upside-down position like an adjacent female that is depositing eggs on the nest’s roof.

Movie s3
This file illustrates a nesting, type I male's "hum" vocalization produced during female courtship.
