Final answer:
The American and Common Kestrels have evolved similar characteristics for hunting in open country with excellent vision, but they do not share the same geographic habitat, reducing competition for food.
Step-by-step explanation:
The American Kestrel (Falco sparverius) and the Common Kestrel (Falco tinnunculus) exhibit similar behaviors and adaptations for hunting, such as being active during the day, possessing sharp, hooked beaks, and having strong legs with clawed feet. These characteristics suggest that both species of kestrel have evolved to hunt in open country, relying on their excellent vision to locate their prey. However, since these birds are found on different continents, they do not share the same geographic habitat. This diminishes direct competition for food sources, allowing for coexistence without significant overlap in their hunting grounds.
