The orioles come in a wide range of colourful plumage, from the burnt orange of the Orchard Oriole to the bright orange of the Northern Orioles (Baltimore Oriole and Bullock's Oriole) to the yellow of the Scott's Oriole and Audubon's Oriole. The female orioles range in a mixture of colours from green, grey and dull orange. All these birds are a joy to listen to and are usually found in the crowns of the treetops, singing their very cheerful songs. The orioles are known for their weaver-style nests, hanging-like baskets that swing in the wind, from tree branches.
There are at least 9 oriole species in North America; the Baltimore Oriole and the Orchard Oriole in the eastern regions and the Bullock's Oriole and the Scott's Oriole in the western regions. The Spot-breasted Oriole is only found in central Florida. There are 4 types of orioles found in the southern states and Mexico, namely the Altamira Oriole, Audubon's Oriole, Hooded Oriole and the Streak-backed Oriole.
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.
