They don't count. They have *number sense*

Counting is an algorithm, which bird brains aren’t capable of. Crows (and some wasps) can just look at something an know how much there is. For crows that tops out around 7.
For humans it’s usually 3-4. Anything above that we split and add or count.

i see, this makes sense
what i heard is that you can walk up to seven ppl into a hunter's blind all together and have them leave one by one, and the crows know all the ppl should all be gone. this sounds like counting to me
but, it might be a myth
