It can be a little difficult to tell male and female geese apart. Other than a couple of autosexing breeds, geese have the same plumage colors. Males and females are also similarly sized and have no real obvious distinguishing characteristics like a rooster’s sickle feathers. So how do you tell the genders apart? Well, it’s fairly easy once you’re familiar with geese. Read on to find out how to tell whether you have a goose or a gander.
A female goose is called, well, a “goose”. She will generally have a shorter neck. She will also be more timid, tending to stay behind the gander for protection. When a goose walks around she tends to have her bill in the air, watching intently. Her voice is lower pitched than a gander’s is.
A male goose is called a “gander”. His neck will be longer and thicker than the female. He will try to place himself between you and those that he wants to protect. He tends to move his head with more snakelike movements and is more likely to try to bite people and other animals. If you approach him when he’s trying to protect his family he will stretch out his neck towards you. The gander will have a higher pitched voice and tends to be more vocal than the goose. They also have, in my opinion, more personality than the females.
Vent Sexing Geese
Geese can be vent sexed, but be aware that you can damage or kill your geese if you aren’t careful. Do so at your own (and your bird’s) risk. Please proceed with caution. If you do want to vent sex your geese, I recommend reading the guide from Metzer’s located at the bottom of this link.
