Fork-tailed Drongo
Perched above a feeding meerkat group, the drongo produces a perfect meerkat alarm call.
The fork-tailed drongo is a con artist. Perched above a feeding meerkat group, the drongo produces a perfect meerkat alarm call. The meerkats flee. The drongo swoops down and steals their food. This happens hundreds of times across the Kalahari, and it works because alarm calls must be trusted - the cost of ignoring a real alarm is death.
But here's the sophistication: drongos maintain a library of false alarms. Research by Flower et al. documented them mimicking multiple species' alarm calls and rotating which one they use to prevent habituation. They're managing their deception portfolio. The con works only as long as most alarm calls remain honest - a frequency-dependent equilibrium where rare dishonesty exploits widespread honesty.
The business parallel is uncomfortable but precise: Trust systems are vulnerable to sophisticated exploitation, and the exploiters win by staying rare enough to avoid detection. Drongos don't break the alarm system - they optimize their parasitism to keep the host alive. Every mature market has its drongos.
Notable Traits of Fork-tailed Drongo
- mimics alarm calls of multiple species
- varies mimicry to prevent habituation
- kleptoparasitic behavior
- Mimics alarm calls of other species
- Steals food while others flee false alarms
- Success depends on maintaining partial honesty

Fork-tailed drongos demonstrate acoustic deception through alarm call mimicry, varying which species they mimic to prevent habituation.
