I can imagine that when you see a bird of prey with a crest on top of its head, you would immediately think of a Harpy Eagle. But there is another fellow in the neighborhood 'walking' around with a crest: Ornate Hawk Eagle.
Let's have a closer look at both the Ornate Hawk Eagle and the Harpy Eagle.
In the pictures you can see an immature-becoming-an-adult Ornate Hawk Eagle and a full grown Harpy Eagle.
Luckily both were doing similar poses:
The Ornate Hawk Eagle (65 - 70 cm) is much smaller than a Harpy Eagle (80 - 90 cm).
Difference in crest:
Difference in appearance:
The Harpy Eagle is known as the worlds' most powerful bird of prey.

I hope that it is now clear who is the most powerful and recognizable predator in the world amongst these two. Otherwise this fellow won't like it at all.
