What must a falconer do if an eyass is the only one in a nest?

When dealing with an eyass, or young bird of prey, the best practice is to leave it in the nest if it is the only nestling. Leaving the bird in its natural environment allows it to continue developing under the care of its parents, who provide essential nurturing, warmth, and protection. Interfering with its natural upbringing can lead to a higher risk of mortality, as the young bird relies on its parents for food and survival during the critical early stages of life.

Furthermore, in many jurisdictions, including Texas, disturbing a nest with an eyass can be illegal without proper permits, as many raptor species are protected by laws that aim to conserve wildlife populations. By allowing the eyass to remain in the nest, one ensures compliance with these protections while also promoting the healthy growth of the bird. This practice also supports broader conservation efforts, which emphasize the importance of maintaining natural habitats and the species that rely on them.

In contrast, options suggesting relocation or immediate removal alter the bird's chances for survival and disrupt its natural lifecycle, which can result in negative consequences for both the individual bird and the population at large.
