Swellow. The blue/red combo is epic.
Starly's family, hands down.
Both design wise and battle wise.
The Starly line for me, as yes, it is the only one I have trained out of them all, but even in design, it looks the best, in my opinion. A much stronger build to it than the others, and an awesome second and third evolution design in particular.
Also, I like its movepool, and cry.

Thanks to my Best Friend Kieko4eva for the banner.
Pidgeot all the way! It's always been my favorite Flying type anyway ^.^
Noctowl, because I love owls.
The Pidgey line. It's easily my favorite design-wise.
Hoothoot line wins this by default for being the only one that isn't generic and interchangeable with the others.
