[ @Everett01 You beat me to it. ] We've learned vast amounts about Therapod Dinosaurs in just the last few decades, finding almost more intact fossils since 2001 than in the previous century... So much of Aviform behavior & physiology seems to be inherited from their ancient dinosaur ancestors. Their unique one way pneumatic lung system (which has even infiltrated into their incredibly strong hollow bones) allowing them to superoxygenate their blood & musculature for the high-speed running which Therapods are famous for (also, eventually for metabolically intensive flight). Feathers initially evolved for insulation (perhaps a hundred million years before flight), with the longer arm feathers being used both in brooding young & likely sexual displays during mating, then adapted for acceleration & stability during high-speed running, gliding (in smaller species) and finally fully powered flight. There's even evidence - from minute particles of p;igment molecules trapped in feather imprints in the fossil casts of Therapods, Paraves, Dromaeosaurs, etc. - which has allowed scientists (& Paleoartists) to make some educated guesses as to the plumage colours of early bird ancestors.

2:54 - That birds mustache is AMAZING!!!
Fun fact: Birds are actually theropod dinosaurs. The same family as Velociraptors and Tyrannosaurs. They're the last surviving ones.

What bird is it at 2:08
It's a Bulwer's Pheasant. A very bizarre looking bird
@@NewScientist Very bizarre indeed! Didn't even know they existed hahahah
