Question

The Mute Swan is a species of bird with an orange-reddish bill and white feathers. It is naturally found in Europe and Asia but can sometimes be found in the United States as a result of the importation of these non-native birds.

Mute Swans are one of the heaviest flying birds and consume up to 8 pounds of vegetation each day. How will the migration of Mute Swans into an area most likely affect the birds native to that area?

Answer 1

First off, because the bird is non native it may introduce new diseases. Second, because it eats so much vegetation, birds may lack materials to build nests or dens.

Answer 2

the native birds will decrease in numbers because there is not enough food for all the birds.
