Baby Bald Eagles have a lot to learn before they reach adulthood. While still in the nest, they practice fanning their wings and jumping into the air to test their strength. When they’re finally ready for their first test-flight, the fledglings sometimes land unceremoniously on the ground until a

Nature has produced some exceptionally strange animals. One such creature is the Oilbird of northern South America. The Oilbird prefers a diet of wild berries and fruits, especially lipid-rich fruits like palm nuts and avocados (which leads to fatty young and the Oilbird's name). This unusual

Grackles are notoriously loud and brazen birds. For all six species native to the Americas, males are iridescent black and females are sumptuous brown. Though these grackles may look the same, they each make their own distinctive ruckus. Though some deem them pests, grackles can also call us to

The Hoatzin is a strange bird, indeed! It looks like it was put together by a committee. But the way it looks isn't the only thing that sets this bird apart.

High in the mountains of Chiapas, the southernmost state of Mexico, a male Highland Guan is performing his territorial display. The Highland Guan perches on a tree-branch, whistles, and then glides on vibrating wings. The resulting wondrous sound is like no other. The bird’s display creates a sound
