Visually guided catching and tracking skills in pigeons: A preliminary analysis

Area of Science:

• Behavioral neuroscience
• Animal cognition
• Motor learning

Background:

• Technological limitations have previously hindered research into avian reaching, tracking, and catching behaviors.
• Understanding the mechanisms of motor control and learning in animals is crucial for comparative psychology.

Purpose of the Study:

• To develop and validate a new technological system for studying pigeon's visual-motor skills.
• To investigate the tracking strategies and learning capabilities of pigeons in response to a dynamic visual target.

Main Methods:

• A novel system using a video display terminal and touch technology was implemented to present a moving target and detect pigeon pecking responses.
• Pigeons were trained to peck at a sinusoidally moving rectangular target, with reinforcement contingent upon coincidence between beak and cursor location.
• Motor learning transfer was assessed by changing the target's trajectory from vertical to horizontal during probe trials.

Main Results:

• Pigeons predominantly employed a lagging tracking strategy, with most pecks occurring behind the target.
• Pigeons exhibited adeptness at "catching" the target across various positions in its trajectory.
• Upon changing the target's trajectory to horizontal, pigeons rapidly shifted their dominant pecking pattern from vertical to horizontal, demonstrating flexible motor skill transfer.

Conclusions:

• The developed system effectively enables the study of complex avian motor behaviors.
• Pigeons display flexible and adaptive motor skills, indicating they learned to track the cursor's movement.
• This research provides insights into the generalizability of learned motor patterns in avian subjects.
