Female cooing promotes ovarian development in ring doves.

Area of Science:

• Animal Behavior
• Reproductive Endocrinology
• Avian Biology

Background:

• Vocalizations play a crucial role in avian reproduction.
• The influence of auditory feedback on reproductive physiology is not fully understood.
• Ring dove (Streptopelia risoria) cooing is a key component of their courtship and social interactions.

Purpose of the Study:

• To investigate the differential effects of self-heard versus male-heard coos on female ring dove ovarian response.
• To determine if auditory stimulation from vocalizations directly impacts follicular development.

Main Methods:

• Playback experiments were conducted using recorded coos from female and male ring doves.
• Experimentally muted female ring doves were exposed to either their own coos or male coos.
• Follicular growth was measured as an indicator of ovarian response.

Main Results:

• Females exposed to their own coos showed significantly greater follicular growth compared to those exposed to male coos.
• Auditory stimulation from self-produced vocalizations had a more pronounced effect on ovarian stimulation than auditory stimulation from conspecific males.

Conclusions:

• Self-vocalization in female ring doves acts as a potent stimulus for ovarian response and follicular growth.
• The findings suggest a direct link between auditory self-feedback and reproductive physiology in female birds.
• This highlights the importance of self-generated auditory cues in regulating reproductive processes in Streptopelia risoria.
