{"fact":"Crows can perform complex cognitive tasks, like using tools and planning for the future, abilities once thought exclusive to primates.","context":"The corvid family of songbirds (jays, jackdaws, crows and ravens) contains some of the most intelligent bird species. Corvids are renowned for their sophisticated behavioral repertoire and cognitive flexibility, traits originally believed to be found only in primates [1,2]. For instance, corvids manufacture and use tools [3,4], take into account the presence of conspecifics during social interactions [5,6], exhibit exquisite spatial memory [7], and show signs of episodic-like long-term memory [8]. Moreover, they flexibly provide for future needs [9], master tests of elaborate object permanence [10,11], and swiftly extract general principles to guide behavior [12–14,15].","source":"Andreas Nieder, Inside the corvid brain—probing the physiology of cognition in crows, 10.1016/j.cobeha.2017.02.005","index":10}
