The Olive-sided Flycatcher is a perch-and-pounce pro, often seen on treetop lookouts shouting its signature call—“Quick, three beers!” (yes, really!). With its vested look and upright posture, it’s like the forest’s stern-but-cool teacher watching over the class. These birds are serious insect hawkers, launching into the air with powerful wings to snag bugs like tiny jet fighters.
