Which species in New Hampshire is protected under the Migratory Bird Treaty Act?

The correct answer identifies that all migratory bird species in New Hampshire are protected under the Migratory Bird Treaty Act. This piece of legislation was enacted in 1918 to implement several international agreements aimed at conserving migratory birds and their habitats. It makes it unlawful to pursue, hunt, take, capture, or kill any migratory bird without a permit, providing a comprehensive protection framework for these species.

Migratory birds are particularly vulnerable due to their travel patterns and the environmental changes they face across different habitats. The protections offered by the Migratory Bird Treaty Act help ensure that these birds have the necessary conditions to thrive during both their migratory journeys and in their breeding areas.

While the other options mention categories like fish, only terrestrial mammals, and only endangered species, these do not align with the specific focus and purpose of the Migratory Bird Treaty Act. Fish, for example, are regulated under different conservation laws, while terrestrial mammals and endangered species have separate protections that do not encompass the migratory bird species rendered vulnerable by habitat changes and hunting pressures.
