Distinguishing between male and female Egyptian geese can be a challenge. One way to tell them apart is by their sound. Males make a raspy hiss, while females produce a cackling sound. Although they are not terribly vocal, when they are feeling aggressive or stressed they will make a great deal of noise.
The males are quite aggressive when mating. Each male performs a noisy and elaborate courtship display, emitting unusually loud honking noises.
