Red-winged Blackbird (Agelaius phoeniceus)

The Red-winged Blackbird is the most common on the plains of Guanacaste and Alajuela, to the northern part of Costa Rica; it is also found on the Caribbean lowlands, in Rio Frio. Their song is unmistakable and has a metallic quality. Males display a red-orange patch on the shoulder, which contrasts nicely with an otherwise black body. They perch on grass in open plains and even on electricity wires to deliver their song.
