Crows can count out loud, a startling new study has revealed, and they may even have the same numeracy skills as human toddlers.
The discovery is the first time that animals have been definitively shown to count by making a distinct number of vocalizations. The researchers published their findings Thursday in the journal Science. Many studies have shown that animals, including honeybees, lions, frogs and ants, have an inherent numerical sense, and another study revealed that black-capped chickadees add more"dee'"trills at the end of their alarm calls to alert to more significant threats.
