Way-finding in displaced clock-shifted bees proves bees use a cognitive map

Area of Science:

• Cognitive Science
• Neuroscience
• Animal Behavior

Background:

• Mammals utilize metric cognitive maps for navigation.
• Insects like bees and ants exhibit remarkable navigational abilities.
• The existence of metric cognitive maps in insects is a key question in cognitive science.

Purpose of the Study:

• To investigate whether bees possess a metric cognitive map.
• To test the alternative hypothesis of a snapshot-based navigation system with sun-compass-referenced vectors.
• To provide further evidence for or against the metric cognitive map theory in bees.

Main Methods:

• Experimentally captured and displaced bees were observed after release.
• A large shift in the sun compass was induced using general anesthesia.
• The accuracy and speed of homeward-oriented flight after error discovery were measured.

Main Results:

• Displaced bees initially flew in their pre-capture direction.
• Upon discovering errors, bees reoriented directly toward their goal.
• Anesthesia-induced sun compass shifts did not affect the accuracy or speed of post-error homeward flight.

Conclusions:

• The results rule out the sun-referenced home-vector hypothesis.
• The findings strengthen the evidence for bees possessing an integrated metric cognitive map.
• Bees demonstrate sophisticated spatial memory and navigation capabilities akin to mammals.
