There's no goose pokemon, so if there was, there'd be a lot in my area.
But, my city has Bats, Bears, Birds, Geese, Coyotes, Deer, Fox, Groundhogs, Rabbits, Raccoons, Skunk, Squirrels and Waterfowl. And we're close enough to the great lakes that most freshwater pokemon would be there and seagulls.
So, Squirtle for sure, maybe a Pikachu or a Magnemite, there's a major power plant nearby so that's in. A Stunky would be pretty damn common, so I'd probably take one of those. find a Houndour breeder, get one of those, and it's the forest city, so I could probably get a Phantump, already live next to a graveyard with a forest attached to it. Head on down to a quarry and get a rock type, Probably a Geodude.
So,
Squirtle, Magnemite, Stunky, Houndour, Phantump, Geodude.
Or if it was 1:1 animal swap
Turtwig, Pikachu, Stunky, Stantler, Hoothoot, Magikarp.
