A more thorough explanation:

The United States Fish and Wildlife Service (FWS or USFWS) is a part of the U.S. Department of the Interior. It is responsible for managing over 93 million acres of land and water, which includes more than 500 national wildlife refuges and thousands of small wetlands. The FWS also enforces laws related to migratory birds, endangered species, certain marine mammals, and sports fisheries.

The FWS manages the Yellowstone National Park, which is home to many endangered species such as the grizzly bear and the gray wolf. The FWS also enforces laws that protect migratory birds like the bald eagle.

The United States Foreign Intelligence Surveillance Court (FISC) is an 11-judge court that hears requests from the Attorney General for surveillance warrants under the Foreign Intelligence Surveillance Act. The court's proceedings and records are usually closed to the public. Its rulings may be reviewed by the Foreign Intelligence Surveillance Court of Review.

The FISC was established in 1978 to provide a legal framework for the government to conduct surveillance on foreign powers and their agents. For example, if the government suspects that a foreign government is planning a terrorist attack on the United States, it can request a warrant from the FISC to conduct surveillance on the suspected individuals or groups.

The United States Foreign Intelligence Surveillance Court of Review is a panel of three federal judges appointed by the Chief Justice to review decisions of the United States Foreign Intelligence Surveillance Court. The court was established in 1978 by the Foreign Intelligence Surveillance Act.

If a party is dissatisfied with a ruling of the FISC, they can appeal to the Foreign Intelligence Surveillance Court of Review. For example, if a person or organization believes that their privacy rights have been violated by the government's surveillance activities, they can appeal to the Court of Review to have the ruling of the FISC reviewed.
