The Meadowlark Tribe refers to the the meadowlark that is the state bird of Oregon. Also on the flag is the Oregon Grape (Oregon's state flower), Douglas Fir (Oregon's state tree) and the Swallowtail Butterfly (Oregon's state insect).
The motto is: "Fly With Your Own Wings" . This is an abbreviation of the Oregon's state motto "She Flies With Her Own Wings". I thought this was good for a merge tribe because now everything is individual and the castaways have to "Fly With Your Own Wings". Also to go along with flying with wings, I used the Meadowlark and Swallowtail Butterfly, which obviously both fly and have wings.
