Green bird species in North America are found in a variety of habitat. These areas range from forests, to wet areas and fields, from running streams to lakeshores, as well as in mountain ranges.
It is not always easy to categorize a bird species by a specific colour. That is because, every year, birds change from a breeding plumage into a non-breeding plumage and vice versa. In some cases, male birds of certain species, such as the Scarlet Tanager, will change from a bright red plumage to a yellowish-green plumage throughout the fall and winter months and then will resemble its female partner. This is also seen in other bird species as well.
Here is a list of different types of green birds seen in North America including native, vagrant birds and others.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.
