What is a traditional strap used by falconers, valued for safety and simplicity?

The traditional strap valued for safety and simplicity in falconry is the bal chiatri. This strap is specifically designed to secure the bird to the falconer's arm while ensuring that the bird can move comfortably without risk of harm. The design allows for a balance between control and freedom of movement, which is essential for the well-being of the bird during handling. Given its simplicity, falconers find it easy to use, making it an integral part of their equipment. Understanding the bal chiatri's function helps falconers prioritize the safety of their birds while maintaining effective communication and control during the training and hunting process.

In contrast, while the other choices involve components of falconry, they do not serve the same role as a traditional strap. The block perch is a type of perch used to hold birds, brails are used to restrain a bird’s wings during transport, and the bow perch is a different kind of perch with a distinct purpose. Each of these tools has its value, but they do not directly relate to the traditional strap concept as the bal chiatri does.
