How to determine the gender of mammals from appearance or behaviour

[Lisbeth]

In nature, it's much easier to see the difference as the male is sturdier, especially the neck and it behaves differently from the fillies, always on guard and staying on the outside of the group.

I think graham's stallion and Sprocky's mare are the most convincing

Observation of behaviour is most likely better!

What next?

How about my brown muzzle pic, with the more sturdy head!

What about leopards, cheetah and hyena? They also don't show sexual dimorphism.

Let's start with leopards. They show notable differences!

[Lisbeth]

The male is much bigger and heavier than the female and has a "double chin". It also has a different expression

But sometimes it is difficult to recognize the sturdiness from a picture. Easier in real again.

What do you mean by expression, Lis?
