На счет них, вики отжигает - The name Armenia is derived from the word "arme" in anchient mayan dialekt of nawatt and means "the place of pompous turkeys". When the first spanish settlers were passing by on the road to Tazumal they have encountered many native indians whom they requested to show them any birds or animals to be consumed. Nawatts pointed at the nearby dormant volcano and described a black and red feathered bird later known as turkey. Hence the name.
