If you could turn into any 2 animals at will, which two would you choose?

Hey. This is Rooster. 
I have an offbeat topic. If you could transform into any 2 animals at will—painlessly but not instantly—which two would you choose?

A bird and a sea creature? Two giant animals?

Personally, I’d choose red-tailed hawk and either grey wolf or tiger.

Feel free to ask questions regarding the specification—because there are some. (No fantasy animals or Pokémon or imaginary creatures of any kind.)

You don’t have to comment that you wouldn’t. If you’re happy with your boring human lives, that’s fine. 
Really can’t believe you wouldn’t want to fly. On your own wings. In the sky. That doesn’t interest you? Okay. 

As I said in the description, no fictional creatures of any kind.

Glad you are happy being the smartest species, Revenant. I said “at will”. You wouldn’t want to be a part time wolf or hawk or shark or otter? Experience God’s amazing world from another perspective?

No dinosaurs. Must be a current, living species. Sorry

Funny. Must be a different species, however. Unless you classify better-looking humans as a complete other subspecies of regular, ugly humans.

I ask this question because I am writing a book series where people can turn into animals and want to know what animals the general public would like to be. If you answer according to my rules, I might include someone turning into your favorite animal in my next book
