The name bem-te-vi comes from Brazil, where generations have transcribed the great kiskadee's call into Portuguese words. The bird is one of the most familiar sounds of Brazilian cities, parks and countryside, heard year-round because it defends its territory loudly from rooftops and wires. As Brazilian videos spread online, editors began lifting the call as a ready-made audio marker for anything set in Brazil. It stays popular because few natural sounds are so short, distinct and culturally specific.
