The Yigüirro was chosen as the national bird of Costa Rica for several reasons. One of them being that the Yigüirro has a wide range and tendency to live close to humans, and therefore is well known and mentioned in many of Costa Rica’s folk songs, short stories and novels. Another reason is due to its strong and melodious song that always comes during the start of the rainy season. The males in particular are cherished for their exquisite song used to serenade potential mates during mating season. In Costa Rica, their mating season (usually April-June) coincides with the beginning of the green season, and therefore—legend has it—farmers have always taken the yigüirro’s song as the first sign of coming rains.
