Predators have an easier time spotting bird nests in fragmented habitat is the correct response.
Fragmented forest habitats often create edges between different types of habitat, which can provide easier access for predators to enter the area. Additionally, when forest habitats are fragmented, they often create patches of smaller and isolated areas, which can lead to a higher density of predators in a smaller area. This increased predator density, combined with easier access to bird nests, can increase the risk of predation on bird nests by predators such as cats, dogs, raccoons, and other animals. Predators have an easier time spotting bird nests in fragmented habitats because there are fewer places for birds to hide their nests, and predators have a greater view of the surrounding area.
