Which family of class Aves is identified by a distinct yellow ring around eyes and beak and has yellow legs?

The family of birds characterized by a distinct yellow ring around the eyes and beak, along with yellow legs, is indeed associated with falcons and related species within the order Falconiformes. Members of this family exhibit a range of physical characteristics that are conducive to their predatory lifestyle, including sharp talons and strong beaks, which are essential for hunting.

Falconiformes, commonly referred to as raptors or birds of prey, are known for their keen eyesight and aerial agility, enabling them to spot and capture prey from considerable distances. The unique coloration, particularly the yellow ring around the eyes and beak, is often used in species identification and can serve as an adaptation for communication among individuals or as a signal to potential mates during the breeding season.

In contrast, the other options represent different families within the avian classification. Accipitridae is another family of birds of prey but includes species like hawks and eagles, which do not typically have the distinctive yellow eye and beak ring. Picidae consists of woodpeckers known for their drumming behavior and unique feeding adaptations, while Corvidae includes crows and ravens, which are more characterized by their intelligence and social behavior rather than distinct coloration patterns.
