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 parent offers further encouragement. Juvenile Bald Eagles are roughly the same size as their parents, but all their feathers are a mottled chocolate brown. They take three or four years to mature into the iconic adult plumage with the distinctive white head and tail.More info and transcript at BirdNote.org.Want more BirdNote?

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-looking bird is longer than a crow, with big eyes and a tiny bill protruding from a giant mouth. Oilbirds roost in extensive colonies in large caves. When the sun sets, Oilbirds emerge from their caves, like huge bats, to forage throughout the countryside for food. Thus, Oilbirds spend most of their lives in complete darkness.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

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.

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 emblematic of the cloud forest of El Triunfo Biosphere Reserve. Clouds and fog roll frequently through the reserve, creating a lush forest wonderland. Cloud forest makes up less than 1% of the world’s forest, and its conservation is crucial. At El Triunfo, the display of the Highland Guan testifies to a conservation success.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

The feathers of a bird are, for their weight, among the strongest structures in the world. The bones of this Magnificent Frigatebird weigh less than its feathers! To further reduce weight while maintaining strength, many bird bones are fused. In addition, the pectoral and pelvic girdles and ribs are joined to make a rigid box that supports those long wings, just as the wings support the bird.More info and transcript at BirdNote.org.Want more BirdNote?
