There has been at least four types of stints that have been seen in North America. The stints are not native birds to the North American continent but are recognized as vagrants. The four stint species are the Little Stint, Long-toed Stint, Red-necked Stint and the Temminck's Stint.
The stints are small shorebirds who display a reddish-orange plumage in breeding season, and makes for the best time to identify these birds.
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.
