Why should a raptor's flying weight be monitored daily?

Monitoring a raptor's flying weight daily is crucial because a bird's weight can indeed vary based on temperature and other environmental factors. Temperature influences a raptor's metabolism and energy expenditure; on warmer days, they may lose weight more rapidly due to increased activity levels or lower food intake. By keeping a close eye on their flying weight, falconers can ensure that the bird remains at an optimal weight for hunting and flying. This practice not only helps in maintaining the raptor's health and performance but also allows the falconer to adjust feeding and training regimens according to the bird's needs.

This focus on weight management helps in preventing health issues that could arise from fluctuations due to environmental changes. Other options may touch upon important aspects of raptor care, but the daily weight monitoring directly addresses the impact of temperature on the bird's physiology and performance.
