Don't forget about the people who only see them flying high overhead or visiting briefly in the spring and the fall. Signs of when winter will begin and end this year at least. And yes I am thinking of Canadian geese. (Moving south where they were hated and even had a urban hunting season was a small culture shock)
Worldbuilding idea: Different cultures with climate overlap should have different cultural associations to the same animals. Like one culture looks at a specific kind of a migratory bird like "these birds are the divine messengers of the Gods, they are more intelligent than humans, as they have souls like we do but they are free of sin. They only visit us in the summer because they spend the winter in Heaven :)"
And on the other end of the birds' range the people are like "these feathered little bastards are too smart for their own good, can and will eat your trash. Some say they taste great when fried with scallions, but I wouldn't eat them after seeing what they eat. They always disappear for rainy season - nobody knows where they go but at least they are gone."
