Previously we’ve visited general corvid intelligence (see previously here and here) and numeracy in bees—and given the recent discoveries of a whale language (not forgetting the Plant Kingdom, ibīdem) and elephantine endonymy—it is no wonder that we learn, via Clive Thompson’s latest Linkfest, that our cawing friends too understand the concept of numbers, according to preliminary studies undertaken at the University of Tübingen. Crows furthermore have been shown to vocalise actual numerals, corresponding to values from one to four consistently and have sophisticated maths skills. More at the links above.
