The experiment I recall from the '50s was with crows. If men went into a blind in the middle of a corn field where crows were feeding the crows would fly up into the surrounding trees. Then the men would leave one or two at a time. If the number were five or fewer the crows would know when the last one had left and immediately come back to feed. With six they were sometimes wrong. With seven or more they would wait and then return cautiously a few at a time. Of course they probably weren't counting, mapping cardinality to sequence, but they had the concept of number.
