Visual marking in mammals first proved by manipulations of brown bear tree debarking

Abstract The rather limited human ability to understand animal vision and visual signalling has frequently clouded our expectations concerning the visual abilities of other animals. But there are multiple reasons to suspect that visual signalling is more widely employed by animals than previously th...
