The Golden Eagle

Postcard US-2711124 to the Netherlands shows a golden eagle soaring over the Mount  Charleston near Las Vegas in Nevada.

One of the best-known birds of prey in the Northern Hemisphere, the golden eagle (Aquila chrysaetos) is the most widely distributed species of eagle. Although considered hawk-like, these dark brown birds have a stance and bearing much like that of an eagle, with a soaring wingspan of 76-92", eyes with an "eagle look", and a "golden" nap. They build their nests with a large mass of sticks on a crag, ledge or in a tree, with a pair alternating between several nests in different years.

National Geographic: Owls

Outgoing postcard US-2869244 to Ukraine, sent on July 3, 2014, has since expired. It shows a tagged northern spotted owl in a redwood forest in California.

After I saw a Youtube video of an owl attacked by a hawk, I was curious about the difference between owls and hawks, all birds of prey. Owls belong to the order Strigiformes, with more than 100 species. On the other hands, hawks belong to the Accipitridae family within the order Accipitriformes. Owls are more active at night while hawks rule the day. That probably partially explain the timing of the above "attack." However, hawks do appear to be more aggressive and territorial. Another popular Youtube Video shows the dramatic moment of a hawk attacking a drone over Cambridge, Massachusetts recently, sending the quadcopter plummeting to the ground.
