Note that it does not say "hunting". Hungry birds can do a lot of damage to crops, pre-modern agriculture usually ran on thin safety margins (against starvation), and bagging a bird that was raiding your food supply is obviously a "two birds, one stone" win.
And between the low strength requirements and cultural factors, it'd be no surprise if managing birds was gender-coded female.
I would replace their "over several generations" with "over many generations". And replace "learned" - the bias sounds instinctive, not trained.
