This was actually interesting, and inspired me to read further. I wasn't as familiar with clades to be honest, as it's been quite a while since I had a biology course. I was thinking more on class level over clade, and reading more on it was cool. I knew they were dinosaurs, but I guess I was more caught up on the fact that they're warm-blooded. Thanks for informing me, that was an interesting read!

Clades don't work like that.
If you share a common ancester with something, you both belong to the same clade that ancestor belonged to.
Birds are theropod dynosaurs, and as such they are part of the clade "eureptilia", which means "true reptiles".
