What does the term "wildlife hazard" refer to?

The term "wildlife hazard" specifically refers to the presence of animals on or near the airfield that could pose a danger to aircraft operations. This encompasses situations where animals, such as birds or deer, may interfere with aircraft during takeoff, landing, or while taxiing, creating significant safety risks. Managing wildlife hazards is a critical aspect of airfield safety because encounters between aircraft and wildlife can lead to accidents or incidents that endanger both passengers and crew.

Conversely, the other options touch on related concepts but do not accurately define the term "wildlife hazard." For example, while wildlife conservation efforts are essential, they do not specifically address the risks posed to aircraft operations. Similarly, the mention of animals using the airport as a migration route points to behavior rather than a safety hazard. Lastly, focusing only on endangered species excludes the broader category of all wildlife that could pose a risk, which is why the correct understanding of "wildlife hazard" is crucial for maintaining aviation safety.
