How did Birds survive when other Dinosaurs types couldn't?
Also, birds are warm blooded, but I thought dinosaurs are cold blooded, any idea when this change might of happened? I'm trying to figure out if some other Dinosaurs types might of them been warm blooded, or if other Birds might of been Cold blooded, etc.
Is there any website or tracking of what the dominant or submissive traits are? Like which one is more dominant than another?

I don't think paleontologists are certain exactly why birds were the surviving lineage but i know there hypotheses around the fact that they could fly between resources, were fairly small and well insulated.
Some dinosaurs were cold-blooded but many were warm-blooded. The maniraptoran therapods from which birds evolved certainly were.
Even some of the large dinosaurs like sauropods were likely functionally warm-blooded due to gigantothermy.

That was my hypothesis too, but then I learned that the Ratite family of birds (ostriches, rheas, cassowaries, emus and kiwis) were SUPPOSEDLY the oldest family of birds and they're all flightless.
Which I thought that blew a hole in that hypothesis, but just now I saw where they believe the Ratite family of birds came from a bird of flight, but later changed to birds of land.

@sstronaut
Yeah the Ratites are secondarily flightless but i think it's still uncertain that the flight capability of other birds is the reason they survived.
It might be for the same reason mammals survived which appears to have been a propensity to burrow, generalist adaptations and again the endothermy and insulation.

Since birds are warm-blooded how do some species survive freezing temperatures without getting frost-bite?

@Diotrephes The same way most other animals do
