About These Birds
Common Raven
The common raven is among the most intelligent birds, demonstrating tool use, future planning, and social manipulation in scientific studies. In many cultures, ravens feature prominently in mythology as creators, tricksters, or messengers. Their complex vocalizations include over 30 distinct calls.
Peregrine Falcon
The peregrine falcon is the fastest animal on Earth, reaching speeds over 389 km/h during its characteristic hunting stoop. Like the bald eagle, peregrines suffered dramatic declines from DDT but have recovered through intensive conservation programs. They have adapted remarkably well to urban environments.
