At contests in Southeast Asia, bird trainers compete to see whose bird is the best singer. From Clive Bell’s article in The Wire:
My colleague, accordionist Mike Adcock, chanced upon one this year in a market in Cianjur, West Java. A dozen cages were suspended high up, while below men with clipboards assessed the singing. In central Jakarta contests can attract hundreds of entrants, passionate bird trainers arriving along with their white-rumped shamas, green bulbuls or hill blue flycatchers. On one level it’s a (largely male) social occasion, on another there’s a lot of prize money at stake. A ten minute video from Phuket in Thailand shows the competitors desperately encouraging their birds from the sidelines, bending the rules by gesturing, whistling or blowing kisses. A bird with potential may be worth as much as a Toyota Fortuner. In fact a belief that it’s unlucky to put a price on a bird means they are more likely to be bartered for goods such as cars. The judges, some of whom are women, are assessing melody, rhythm and volume. One contest in Phuket demands that birds sing eight specific pitches within a defined time period…
Many of us probably feel that natural birdsong, encountered in the wild, is a particularly beautiful form of sound, and needs protecting, rather than improving via human intervention. But there are plenty who believe, for both financial and aesthetic reasons, that birds could do better, and that thorough education can raise a bird to greater heights of achievement. It’s one more type of animal breeding, as we’ve practised for centuries.
