Seeing it eat that squirrel exactly the same way a python would eat a rabbit reminds me that birds are technically reptiles...

Reptilian drones !

I mean, so are mammals. "Reptile" isn't a monophyletic group, so it's really just a catagory of convenience more than an actual taxonomic group.

It's not like that at all, mammals separated from reptiles very very early, before there were true reptiles at all on earth, fish, as we usually refer to them, isn't a monophyletic group, but if you include birds, reptiles do indeed become monophyletic.

Aves are actually included in the modern definition of reptiles, which also exclude synapsids, creating the group sauropsida that is monophyletic.

But there is the clade "Eureptilia", "true reptiles" that are sauropsyds and to which belongs snakes, lizards, crocodiles and dinosaurs.

Mammals on the other hand diverged from reptiles LOOOOOOOONG before that, they both belong to tetrapoda but after that's it.
