Grasshoppers do but butterflies (the ADULT stage of a caterpillar) do not (the caterpillars do though).
yes, they can
No Ducks do not eat Grasshoppers.
Yes. They both will. Farm geese and ducks will eat them whilst they are green, and have not yet seeded.
because ducks eat it before u can see the dead geese
Grasshoppers do not eat butterflies or other insects. Grasshoppers are herbivores that only eat plants. Their favorite foods are wheat, corn, alfalfa, and barley, but if those things are not readily available, they will eat many other kinds of plants.
Much like chickens, geese and ducks will eat mice. It depends on the bird.
Don't think it's part of their diet but won't hurt them if they eat a little
Ducks, geese, rails, and shorebirds. Muskrats eat the stems and roos
Chickens, ducks, turkeys, quail, pheasants, doves, geese, pigeons
um wow... THEY DON'T EAT PLANTS!!! They are birds of prey. That means that they eat tings like geese, ducks, and waterfowl.
Both like algae, bread, nuts, vegetation (yes you may feed them vegetables and eggs, though find out directions on how to prepare these), specially made pellets, duckweed, meat (look for directions here too), fish and other pond animals. Actually from what I understand geese are vegetarian...good food for them are rolled oats
