These beautiful vocalizations are of the Tropical Mockingbird (Mimus gilvus), one of the most common birds on Curacao, as well as on Bonaire and Aruba. The local name is Chuchubi, which approximates one of the sound-combinations that these birds produce. They are strictly territorial and will defend their nesting grounds against intruders, even of their own species, with lots of aggression. Especially in early morning and late afternoon the song is most melodious. The birds have favorite perches in high spots, and even a spiny cactus branch will do nicely. From this vantage point their song is transmitted in order to notify others of the fact that the territory is taken. In general they’ll receive answers from different directions. This musical ‘arm-wrestling contest’ keeps things organized in Chuchubi-country. The birds even have the capacity to mimic other sounds, just like their North American family. Hence the name Mocking-bird.
