Corvid Cognition: Something to Crow About?
نویسنده
چکیده
New research indicates that crows are capable of matching stimuli on the basis of analogical relations: that is, similarity of size, color and shape. This may be the first evidence for spontaneous analogical reasoning outside of the primate order.

Corvid cognition
What is a corvid? There are just over 120 species of corvids, a family of songbirds that includes the crows, ravens, rooks and jackdaws, as well as the more colourful jays, magpies and nutcrackers. Although belonging to the same order as nightingales and other birds with melodious songs (Oscines), corvids tend to be identified by their raucous calls. Little is known about corvid songs, perhaps ...

متن کاملAbstract rule neurons in the endbrain support intelligent behaviour in corvid songbirds.
Despite the lack of a layered neocortex and fundamental differences in endbrain organization in birds compared with mammals, intelligent species evolved from both vertebrate classes. Among birds, corvids show exceptional cognitive flexibility. Here we explore the neuronal foundation of corvid cognition by recording single-unit activity from an association area known as the nidopallium caudolate...
متن کاملRooks Use Stones to Raise the Water Level to Reach a Floating Worm
In Aesop's fable "The Crow and the Pitcher," a thirsty crow uses stones to raise the level of water in a pitcher and quench its thirst. A number of corvids have been found to use tools in the wild, and New Caledonian crows appear to understand the functional properties of tools and solve complex physical problems via causal and analogical reasoning. The rook, another member of the corvid family...
متن کاملIs primate tool use special? Chimpanzee and New Caledonian crow compared.
The chimpanzee (Pan troglodytes) is well-known in both nature and captivity as an impressive maker and user of tools, but recently the New Caledonian crow (Corvus moneduloides) has been championed as being equivalent or superior to the ape in elementary technology. I systematically compare the two taxa, going beyond simple presence/absence scoring of tool-using and -making types, on four more p...
