Pigeons can distinguish human faces by sex using visual texture, not shape. They effectively utilize complex visual information, generalizing their learning to new instances based on key distinguishing features.

Area of Science:

Comparative psychology
Animal cognition
Visual perception

Background:

Pigeons previously discriminated human faces by sex based on visual texture.
This discrimination was independent of shape and average intensity differences.

Purpose of the Study:

To investigate pigeons' flexibility in using class-distinguishing information from complex natural stimuli.
To determine if pigeons utilize category-level feature dimensions for face categorization.

Main Methods:

Principal component and discriminant function analysis to identify key facial features.
Systematic transformations and feature reduction to test categorization control.
Evaluation of classification ability with impoverished facial stimuli.

Main Results:

Pigeons' categorization was controlled by specific stimulus aspects that best divided male and female faces.
Enhanced classification was observed with faces varying along the first three principal components.
This indicates reliance on class-distinguishing stimulus aspects for generalization.

Conclusions:

Pigeons demonstrate flexibility and efficiency in utilizing complex visual information for categorization.
Their ability to generalize relies on identifying and using key category-level feature dimensions.
This research provides evidence for sophisticated visual processing in pigeons.
