Did you get a look at the top of the head or its tail feathers? I can’t tell if maybe it’s an ovenbird or a hermit thrush. If you find more of these beauties, you can document where and when you found them, and bring them to the Field Museum.

So, you may be wondering, how exactly do you tell the difference between one fox and another? How could I tell I was looking at a stranger, all foxes look the same, right? Wrong! Every fox has slightly different features and markings, and by identifying those subtle differences it’s possible to tell apart large numbers of foxes. 

Here’s an example with Half-brush and the young vixen. From a distance and in dim-light they both look very similar and are about the same size, but there are a few things that set them apart;

  • Half-brush has prominent black markings on her upper leg just above the ankle. The young vixen lacks any black fur in that area.
  • Half-brush has quite a long tail that almost touches the ground, while the young vixen’s tail is much shorter. 
  • Half-brush has a lot of black in her tail and a small, pointed white tip. The young vixen’s tail is much paler, with a blunt end and lacks any white at the tip. 

There are also a few more subtle differences in the color and length of the coat, as well as their individual behavior traits, although those may take longer periods of observation to recognize. You can also look for scars and nicks in the ears that can help with identification. So although the two may appear to be almost identical at first glance, on closer inspection they are easy to tell apart!
