dinosaurs are birds
modern birds are avian dinosaurs
we now know feathers evolved during dinosaur days
several types of dinosaur had hollow bones, just like birds
theropods were warm blooded like birds
several species of dinosaurs ate stones for digestion like birds
several types of dinosaurs had beaks and bills, just like birds
and now from scans of several specimens we know that dinosaurs had a very similar breathing/circulatory system to birds
emus still have tiny arms/wings with claws, similar to trex

you will never look at birds the same way again
