There is no way to visually tell the difference between male and female Goose. This species is 76-110 cm (30-43 in) long with a 127-180 cm (50-71 in) wing span.[3] Males usually weigh 3.2�??6.5 kg, (7�??14 pounds), and can be very aggressive in defending territory. The female looks virtually identical but is slightly lighter at 2.5�??5.5 kg (5.5�??12 pounds), generally 10% smaller than their male counterparts, and has a different honk. The gander has a slower, low-pitched "ahonk" while the goose's voice is a much quicker and higher-pitched "hink". Mated pairs will greet each other by alternating their calls so rapidly that it seems like only one is talking. A careful ear will be able to put each voice with its rightful owner, which is mighty helpful since the male and female look alike. The goslings have a wheezy soft call that may be either in distinct parts - "wheep-wheep-wheep" - or a drawn out whinny - "wheee-oow". Anyone who has raised domestic geese will immediately recognize these calls.
