A recent study led by neuroscientist has shown that carrion crows can count out loud, a first for non-human species. Researchers trained three crows to produce specific numbers of caws (one to four) in response to visual and auditory cues. The crows successfully completed the task, though they occasionally made minor errors. This ability suggests crows use a non-symbolic approximate number system, similar to how toddlers count before mastering cardinal numbers. The findings highlight crows' sophisticated numerical understanding and vocal control, indicating a potential evolutionary precursor to symbolic counting. The study underscores the advanced cognitive abilities of crows and suggests a new dimension to avian communication.Read more - https://tinyurl.com/mws4y9y3#todayilearned #sciencesphere
