Go to the Cornell Lab of Ornithology website and play the sounds of the bird you want. Believe me, it works.
Birds get attracted to worms because they are hungry, and worms give off a good smell and taste to the birds. So when they see a worm, they want it.
Mostly because of the food they can find in the water, under the water or at the water's edges
Birds are attracted because they are warm blooded and warm blooded animals need to drink water to refresh themselves
It is, but the lif generated by its wings is strong enough to overcome that attraction.
