What is included in a bird activity advisory?

A bird activity advisory provides critical information relevant to pilots and air traffic controllers regarding the presence and behavior of birds in a specific area. The correct choice outlines essential details captured in such an advisory, which include the Course of flight the birds are taking, their Altitude, Position, and the Species/Size of the bird. Understanding these factors can help pilots make informed decisions to avoid potential bird strikes, enhancing flight safety.

Capturing this information allows for proactive measures to mitigate risks during flight operations. Other options, while they contain pertinent information, do not specifically address the focus of bird activity advisories that are designed particularly to communicate bird presence and behavior relevant to aviation safety.
