When not one but two naturalist sorts agree that it was a red fox and not a coyote pup Chris Howe captured on his phone, I will go with the biologists. The original entry is posted below.

ORIGINAL ENTRY
Chris Howe caught this coyote pup in the south suburbs on his cell phone last week. I tried to pull out the photo better on flickr.He sent this this:
``My wife and I saw this coyote pup on 110th and Bell on this past thursday. I know the pictue is kinda blurry, but it was the best I could get with my cell phone cam.''In a follow-up, he said it was definitely a coyote pup and not a fox.
It's just neat to see stuff like that.

This is a red fox- not a coyote. Red foxes have a white tip on their tails; coyotes have a black tip. And the other markings (white chest, black legs), body and tail size are all red fox.

I agree that that is definately a fox.
-Much neater that seeing a coyote.
yes, definitely a red fox, long tail with white tip, pretty diagnostic
and a coyote pup would not be by itself
foxes are pretty common, just very difficult to spot
nice photo of a fox with your cell phone
