这项研究检查了野生捕获的澳大利亚虎皮鹦鹉（Melopsittacus波动）的听觉和接触叫声，并将这些数据与更广泛研究的家养虎皮鹦鹉的听觉和发声进行了比较。无论是野生捕获的虎皮鹦鹉还是驯养的虎皮鹦鹉，其接触叫声的频谱能量几乎完全落在2-4千赫的频率上。两组鸟类的绝对阈值和隐蔽阈值相似。与驯养鸟类的结果相似，野生虎牙的临界比值函数在1.0 kKz-2.86 kHz频率范围内下降，然后在2.86 kHz以上频率范围内急剧上升。
This study examined the hearing and contact calls of wild-caught Australian budgerigars (Melopsittacus undulatus) and compared these data to hearing and vocalizations in the much more extensively studied domesticated budgerigar. The spectral energy in the contact calls of both wild-caught and, domesticated budgerigars falls almost exclusively in the frequency of 2-4 kHz. Absolute and masked thresholds were similar in both groups of birds. Similar to the results found in domesticated birds, critical ratio functions for the wild-caught budgerigars decreased at frequencies of 1.0 kKz-2.86 kHz and then increased again dramatically at frequencies above 2.86 kHz.
