If they know that the gallinoansera clade had already emerged before the K-T extinction, they most likely also know about birds being dinosaurs. Specifying “non-avian” everytime is a pain and saying “K-T extinction” is not understood by all, no need to correct them for semantics when their wording gets the point across.
If any bird still acts like it thinks it’s a dinosaur, it’s those goddamn Canadian Geese.
Geese, ducks and chickens had all already evolved when the dinosaurs went extinct. They are all tough hombre.
Have you not been reading this thread? Dinosaurs never went extinct. A sparrow is descended from the great raptors
