Wherever there might be brambles, long grass in meadows or cattails, there are probably wrens close by. These small brown birds are more often heard than seen and when seen, they usually have their tails pointing up. Even when they are in areas where they are known to exist, it is still no guarantee that one will be seen.
There are nine species of wrens in North America and eight of these have been reported seen in Canada. They are as follows: Canyon Wren, Carolina Wren, Bewick's Wren, House Wren, Marsh Wren, Rock Wren, Sedge Wren and Winter Wren. The Cactus Wren is located in the most southern states.
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.
