People everywhere ive been go apeshit over a squirrel.

In the Pacific Northwest I’ve had visitors get really excited to see slugs.

Black bears, mountains southeast USA

Moose. We get European summer students and seeing one is the highlight of their animal watching when they're here, apparently.

Personally, I'm more impressed with elk, a bull elk with a full rack is pretty awesome.

Had some people visiting from Columbia. The squirrels absolutely blew their minds.

It's wild to me that there are wild macaws in northern South America. Granted I haven't seen them in person, but even videos of them look so weird, like a hundred people let their pets out on accident.

Guaras, or Guacamayas, I suppose. Think they're called Macaws in english. They're neat, pretty feathers and all. Shame they're hardly ever visible outside of a zoo, unless you're in the right spot at the right time and you're really paying attention.

Swans. It's a wonder to me that such an arrogant bird ever became the national pride of Denmark. But tourists freak out about them, thanks to H.C. Andersen.

Koalas

Alligators. (I live in South Louisiana, which is a separate country for all intents and purposes.)

Most USians probably expect to see monkeys and capybaras crossing the streets here in Brazil. There's a good chance to see the latter near most freshwater bodies, even in the capital, though monkeys will vary a lot more from place to place.

In Rural America- "people of Walmart"

In UK people come from all over the world to see our royal family of great apes.

I had a relative visiting the US for the first time who was really excited to try turkey meat.

Armadillos

Peacocks. Where I live (central California) there is a local park that has a flock of wild peacocks. I had a friend visiting from Korea and he was so excited to see them.

When I first moved, I was happy to just see some robins.

I still get a giggle when I see them pretending to be the Amazon delivery crew.  

Monkeys in a very snowy forest. I remember feeding them nuts once.

They're called macaques.
