Male Physical Characteristics

• Males heads are a wide fat triangle shape compared to females more narrow tall triangle shape.

• Males tails are more fat at the base and then taper down (this is a hard one unless you have something to compare it to).

• Males have a more developed beard area, their cheek/jugular area is larger than the females

• Males are more likely to display a black beard and bob extremely aggressively as their courting behavior.  

• Females may also display a black beard so don't just say black beard equals male!

• The femoral pores (pores on the inside of each back leg) on a Male are more developed, they actually look like a pimple with a flat head on it, they look "open"

• There is also a way to tell based on the bulging in the vent area when pressure is applied in the right way, however you can hurt/damage the dragon if you don't know what you're doing.

Female Physical Characteristics

• Females have a narrower head (side to side) then males do, females have a more narrow, long, tall triangle shape

• Females tails taper pretty consistently down, their tail base is narrower in general (this is a hard one unless you have something to compare it to)

• Females are more likely to wave slowly and bob more deliberately and slowly, females may display a black beard so don't just say black beard=male!

• The femoral pores (pores on the inside of each back leg) on a Female are not nearly as developed, are rather small, and often don't have as much of a "pimple head"

• There is also a way to tell based on the bulging in the vent area when pressure is applied in the right way, however you can hurt/damage the dragon if you don't know what you're doing.
  

Start with the sexing hints and suggestions above and see where that gets you.  Generally you can be pretty certain of the sex if the dragon fits a few of the descriptions above for that particular sex, some dragons are tricky depending on their age/size, but you can get pretty close to sure based on the info above...good luck!  There are some great sexing photos here:  http://www.beardeddragon.org/articles/sexing/
