I just got back from a long bike ride and saw yet another squished armadillo, and that got me to thinking about this very important topic. Even though this isn’t an opinion question, I’m putting it here because a poll is on its way.
Darn, I forgot the one that’s my answer: Squirrel!!! Any way to edit the poll entries?
You don’t see much roadkill in my area. I guess it’s seagulls, but only just.
edit: Rabbits too.
Gophers. Sorry, Richardson’s Ground Squirrels, which are commonly known as gophers on the prairies.
I even made up a joke about it - “Why did the gopher cross the road? To prove it could be done.” 
Squirrels are the most common, but there are also a fair number of raccoons, skunks, and porcupines. Chipmunks and foxes are far more rare as roadkill, though I’m not sure why in the former’s case since they’re no brighter than the grey and red squirrels when it comes to darting out in front of cars. Woodchucks and rabbits are pretty rare considering their populations too.
Fortunately big things like deer, bears, coyotes and moose seem shy-er around traffic, or there’d be a lot more damage to cars.
Awww, it looks like someone painted a chipmunk beige.
I also vote for squirrel.
Badger.
I don’t expect it’s the most common, but it’s the one I most commonly see. Smaller animals such as pheasants, rabbits and songbirds are probably killed more frequently, but are collected by scavengers fairly quickly. Badgers tend to stay put once killed.
Yeah, I could kick myself for forgetting to include them in the poll. :mad:
Where are you? I don’t think we have badgers here in Florida (although I could be wrong; I didn’t think we had otters until I saw one crossing the road).
Don’t you be “awwwing” the gophers, devil beasts that they are (they kill horses and cows all the time - the holes are just the right size for leg-snapping).
I guess most people round here would say hedgehogs, and they are renowned (justly or otherwise) for being squished by cars. But my impression is that it’s mainly birds, rabbits and foxes. In the urban area where I live, I guess rabbits are less common.
I voted deer, but that may be the most roadkill only by total mass.
Porcupines and skunks probably think they are immune to injury due to their defense system, but I can’t explain the reasoning of squirrels and chipmunks, who dart across the road on a suicide mission. Deer will run along your car at full speed or wait until you come up to them, then instead of veering away, charge headlong into the vehicle or the vehicle’s path. I think they are paid by the auto body shops.
Skunk.
Oh. Chipmunks are ground squirrels too, but they have wee little holes that don’t seem to bother our hoofed friends.
Kind of a tie here. Skunks and deer.
I see at least one or the other every week.
Raccoons by far. Every spring through fall, I find myself wondering if they have some kind of suicide pact going on. I see dozens by the side of the road. Actually “dozens” seems conservative.
By contrast, in the eight years I’ve lived in this area, I’ve seen exactly one deer, one rabbit and one fox dead on the side of the road. (I’ve seen plenty of live specimens of each, so I know they are around.)
Squirrels, skunks, and opossums are a little more common, but don’t come near matching the sheer number of raccoon corpses.
Out amidst the cornfields it’s raccoons by far followed by possums and then deer. In town (where I live) it might be squirrels first and then possums.
Due (I think) to the drought last summer/fall I noticed an unusually large number of snapping turtle road kill. I believe they were moving around more as smaller bodies of water began to dry up.
Toss up between chipmunks/squirrels and porcupines, here in Maine.
I don’t know for sure that deer are numerically the most common. But a dead deer is more noticable than a dead squirrel or dead possum.
Suicidal frogs. Seriously, I have never seen so many frogs until I moved to this town. I almost felt like I was in a plague of frogs last summer. While driving through my town at midnight one night, I squashed at least 10 suicidal frogs. I love frogs. It really bothers me but they’re impossible to miss.
There’s a highway I travel frequently that’s not an interstate but most traffic is travelling at interstate speeds and there’s cornfields and woods on both sides of the highway. The deer kills are often quite spectacular. When they get hit by a semi they seem to explode with blood and parts strewn over an impressive stretch.
