Hunters believe that Canadian geese are the smartest birds.
I found it very interesting that the geese are monogamous throughout their lives unless their mate dies. Humans could learn a lesson from them!
These geese have very good eyesight. They can see more than 180 degrees horizontally and vertically which is very useful during flight. Canadian geese also have mostly monocular vision.
Canadian geese have a large lifespan. As an extreme, some can live up to twenty four years in the wild. However, most die within the first year of their life because of predators.
There are eleven subspecies of Branta canadensis- and they range from being the biggest to one of the smallest geese in the world.
Branta canadensis maxima was endangered in the 1900s. Programs were set up to save these geese, and it has been considered too successful. Now they live in residential areas and are considered annoying neighbors to many humans.
Canadian geese can travel more than 1000 kilometers in a day while migrating. The circumference of the world is 40008 km. This means that they could fly around the world in approximately 40 days!
In 1971, the Ramsar Convention on Wetlands took place. The convention was a waterfowl conservation project. All parties were required to have a wetland region in their country that supported at least twenty thousand birds. By 2002, 130 countries were involved. Over 917,000 square kilometers were wetland areas.
In many cases concerning geese and birds, the voices of males and females are different. With the Canadian goose, females have the lower voice.
Birds are considered the most successful vertebrates. They outnumber mammal species twofold.
Branta canadensis have greater diversity of nest sites than all other species of waterfowl.
