There are two types of tattlers found in North America and both bird species are mostly seen on the western coastlines of the Pacific. The Wandering Tattler is the most common of the two and is considered a native bird whose breeding area is in the northern hemisphere. During the winter months, it is found along the southern coastal states and Canada. The Gray-tailed Tattler is more so an Asian bird and is observed in the spring and fall migration periods on the islands in the Bering Sea.
The tattlers are mainly solitary shorebirds and not likely to be observed in large flocks. They are usually seen searching the rocky areas of coastlines. During their nesting season these same birds may be found along freshwater mountain streams far away from the coast.
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.
