Both seagulls and wild geese are large birds. they're also similar in that both kinds of birds can fly over great distances. on the other hand, seagulls are scavengers, while wild geese aren't. seagulls, for example, are often found around garbage dumps. geese, however, feed on things like seeds and insects. another important difference between the two kinds of birds is that geese fly on long annual migrations of well over 1,000 miles. seagulls will migrate far inland to search for food. however, they don't follow seasonal patterns of migration like wild geese.
