A variety of sub-species in the Brant family are seen in North America. These sub-species or races range in colours from dark black through to very light shades of grey. The Black Brant is a native goose of the northwestern regions of the continent. These colours tone down in shades of grey as they are seen, going from west to east in North America, to the very light coloured Pale-bellied Brant of the Atlantic regions. These birds can also be seen with brown plumage. Brant breeds on the tundra and the high arctic arriving on the nesting grounds when there are still signs of snow and ice.
Brant is a member of the goose family and is considered one of the smaller geese seen on the continent. Unlike most geese, Brant do not fly in an organized "V" pattern but bunch together like flocks of birds, such as the blackbirds. They have a unique call which makes them easy to recognize.
Avibase - the world bird database This site provides the user with a complete list of bird species, broken down per country, or in the example of the US or Canada, per state and province. Here, bird species names are available in other languages, a great asset to be used as a translation of foreign bird names.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
I hope you will take advantage of these suggested websites. I have used each of them, in one way or another, throughout the years in my quest to better identify and understand our fine feathered friends.
