Examples include the red-tailed hawk of North America and the common buzzard of Eurasia. Most Northern Hemisphere species are at least partially migratory. In North America , species such as broad-winged hawks and Swainson's hawks are known for their huge numbers (often called "kettles") while passing over major migratory flyways in the fall.
Unlike some birds, but similar to other diurnal raptors, most hawk species are violet-sensitive but cannot perceive ultraviolet light. [11] Hawks also have relatively high visual acuity – the distance at which they can resolve an image – with red-tailed hawks reported to have 16.8 cycles per degree. [12]
