Why is it advised to stop flying birds before spring?

Stopping the flying of birds before spring is advised due to a combination of factors that affect both the falconer and the birds. During spring, soaring weather patterns can create conditions that are risky for flying birds of prey. This type of weather can lead to unpredictable thermals that make it difficult for a falconer to maintain control over their bird.

Additionally, as spring approaches, many birds experience hormonal changes that promote migration. This can lead to their instinct to leave their current territory, which can distract and unsettle a trained falcon, making it harder to maintain focus during training or hunting.

Furthermore, the influx of migrating birds also complicates the situation. The presence of numerous unfamiliar birds can lead to increased competition for food and territory, which further stresses the falconry bird and can lead to more aggressive or erratic behavior as it attempts to assert dominance or hunt.

Therefore, the correct response acknowledges that all these factors—dangerous weather, hormonal changes in the birds, and increased competition—make it prudent to halt flying activities before the onset of spring. This approach helps protect the well-being of both the falconers and their birds.
