How do the feet and cere color differ between first-year and adult Prairie Falcons?

The feet and cere color of Prairie Falcons provide important visual cues to differentiate between first-year birds and adults. In this case, first-year Prairie Falcons typically exhibit blue feet and cere, which can help in identifying their age. As they mature into adults, their feet and cere change to a more distinctive yellow color. This color change is consistent with the development and maturation process observed in many raptor species, indicating the bird's age and maturity level. Understanding these differences is crucial for falconers in identifying and properly caring for their birds.
