According to The National History Museum, "birds evolved from a group of meat-eating dinosaurs called theropods. That's the same group that Tyrannosaurus rex belonged to, although birds evolved from small theropods, not huge ones like T. Rex".
The Black-Crowned Night Heron although small in stature, stalks shallow creeks & ponds and their shorelines for fish & small prey, including young muskrats. Watching the heron in its hunting mode, creeping along the edges like a cheetah consistently in stealth mode, makes one thankful for its small size & less ferocity than the Velociraptor. But on my, those ruby red eyes!
