Food and token quantity discrimination in capuchin monkeys (Cebus apella).

abstract：:We examined inferential reasoning by exclusion in the Clark's nutcracker (Nucifraga columbiana) using two-way object-choice procedures. While other social scatter-hoarding corvids appear capable of engaging in inferential reasoning, it remains unclear if the relatively less social nutcracker is able to do so. In an in...
