There are so many! Look at what kinds of plants geese seem to prefer vs what swans and ducks prefer. Look at whether the presence of another species (eg geese/swans/hens) affects whether ducks will go there, and same for the other species. Look at whether rabbits are responsive to bird calls (like for danger), i.e. if a bird gives a danger call do the rabbits notice, and run, or do they ignore the birds altogether?
That's just a few off the top of my head. Hope it helps!
