The first thing to determine when looking at a bear is whether it's a sow or boar. Sometimes this is easy, but it can be hard to tell the difference between a big sow and medium-size boar. In brown bears, the face is one of the biggest giveaways. If you look at a lot of bears, it is pretty easy to see that sows generally have a short, pointy muzzle, whereas a mature boar has a distinct long, rectangular snout. Body-wise, sows are usually more compact with shorter legs and necks than their male counterparts. Even medium-size boars usually look lanky with a long neck, and they walk with a long, striding, shoulder-rotating gait.
