Hawks, Eagles, and Kites

Summary

In this episode, Ivan takes on one of the most iconic bird families in the avian world: Accipitridae—the hawks, eagles, kites, buzzards, harriers, and Old World Vultures. It's a massive and diverse group with no good nickname, though Ivan has a few suggestions.

The episode covers the key traits that make these birds such formidable predators—from their hooked bills and locking talons to the bony "brow ridge" that gives them their signature scowl. Ivan also digs into the family's staggering diversity: 249 species across 73 genera.

Along the way, there's some evolutionary biology, a Weirdo Alert, and a look at the ancient giant that makes today's largest eagles seem modest by comparison.
