There are three types of grassquits found near the North American continent. These are the Yellow-faced Grassquit, Black-faced Grassquit and the Cuban Grassquit.
All three of these species are found in the West Indies and have been reported seen as vagrant birds, who were probably blown onto the mainland by storms or strong winds.
Grassquits are ground feeding birds and are recognized as being in the same family group as sparrows. These large billed birds are seen along the edge of the forest or in fields where they feed on seeds of various plants.
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.
