Figure 3.  The Andean Condor (Vultur gryphus) is the only species of New World Vulture that is sexually dimorphic (i.e. the male and female look recognizably different).  The male is larger in size than the female, has a large comb extending from the top of the head down to the top of the beak, and possesses large wattles on the neck.
