Question

a
Rats and mice are poisonous to the birds
b
The birds build their nests on the ground since there are no trees on the island.
c
The birds compete with the rats and mice for the same food resources.

Answer 1

b. The birds build their nests on the ground since there are no trees on the island.

Rats and mice can be dangerous to pipit and pintail birds because these birds nest on the ground, making their eggs and chicks vulnerable to predation by rodents.
