In which order does the moult typically begin in birds like parabuteos, buteos, and accipiters?

The correct order of moult in birds such as parabuteos, buteos, and accipiters typically begins from the innermost primary feather outward. This pattern is crucial for maintaining optimal aerodynamic performance and balance during flight. By starting the moult process at the innermost feathers, these birds can retain adequate flight capabilities while losing older feathers and growing new ones.

Moulting from the inner feathers outward allows for a staggered replacement that minimizes the impact on flight efficiency. This strategy contrasts with other potential moult patterns, such as beginning from the outermost feathers, which could lead to a more significant disruption in flight capabilities if multiple outer feathers were lost simultaneously. Starting the moult in the middle ensures that the bird maintains its ability to fly while the new feathers are developing, thus aiding in survival and hunting efficiency.

Understanding the moult pattern is essential for falconers and bird enthusiasts alike, as it influences several factors, including the bird's health, behavior, and its ability to hunt effectively during the moult period.
