I don't know the names of most birds, this one I call the "MOM" bird because of it's call. If you have ever seen the commercial for the animated series The Family Guy, where stewie is constantly saying "Mom, mom, mom, mom, mom, mom ...", well that is what this bird sounds like. Some people think it sounds like "WOW", but I can tell you they must be upside down, it is definitely "MOM"!
