There are a variety of sub-species of the Eastern Meadowlark seen in North America, Central America and on the Caribbean islands. Only the Eastern Meadowlark (Eastern) migrates to a warmer climate during the winter months. Some will even outlast winter in the grassy fields surrounding the Great Lakes, where the temperatures are more moderate. The Eastern Meadowlark (Lilian's) and the Eastern Meadowlark (Cuban) are more likely to stay in the same habitat areas 12 months of the year.
Meadowlarks are members of the Icteridae family and belong to the same group of birds as the blackbirds, cowbirds, grackles and orioles. They are found on hayfields and pastures and are recognized by their bright yellow breast, black V-type collar that reaches down into their yellow breast and their melodious songs and rapidd wingbeats.
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.
