I wonder why the quotes around "count" are required.
> The crows flexibly produced between one and four vocalizations for corresponding cues associated with numerical values. Furthermore, they used different calls for different numbers.
Is this because the crows might just remember four separate stimuli, and did not demonstrate an understanding of integers in the Peano arithmetics style? I still think that producing a specific number of vocalizations, well, counts as counting.
