摘要
于2005年4月采集到笼养朱鹮(Nipponia nippon)4种行为状态的鸣叫声,对其繁殖期求偶鸣叫、交尾鸣叫、假交尾鸣叫和惊叫的鸣声特征进行了分析,探讨了不同行为状态的鸣声差异。求偶鸣叫振幅小,主要频率范围在156±13.2 Hz-1 568±120.3 Hz之间(n=30),声谱谐波丰富,频带呈直线型和拱型。交尾鸣叫由7-21声连续、急促的鸣叫和一声长鸣组成,声音宏亮有力,频域特征表现为主频呈现双峰,主要频率范围在346±16.7 Hz-2 396±138.2 Hz之间(n=14),音节高度重复并多有谐波。假交尾叫声有三种声模式,模式1包含2-10声短促鸣叫声和一声长鸣;模式2仅发出多声短促鸣叫声;模式3仅一声长鸣,频域特征在三种声模式下表现不同,模式1主频呈现双峰,模式2和模式3仅有一个峰值,主要频率范围在328±18.2 Hz-2 067±189.1 Hz之间(n=38),声谱多谐波,频带形状呈下滑状或直线状。遇险惊叫声信号振幅最大,每一声信号中包含多个脉冲组,惊叫声主频较高,主要频率范围在375-2 300 Hz之间,声谱多谐波,低频频带呈直线型,高频频带呈半拱形,声音末尾有明显的降调。
In this study, the vocalizations of the crested ibis Nipponia nippon were quantitatively analyzed. Calls recorded during the breeding season included courtship call, mating call, mimic mating call and scaring call. The characteristics of each call were extracted and analysed. Results show that the amplitude of the courtship call is small, with a main frequency range of 156 ± 13.2 Hz - 1 568 ± 120.3 Hz （ n = 30）. Its spectrogram is multi-harmonic with frequency bands of line and half-arched structure. The mating call has two stages. The first stage consists of 7 -21 continuous syllables. The second stage is a single long syllable. The call is loud and contains two principal frequencies. The main frequency range is 346 ± 16.7 Hz - 2 396 ± 138.2 Hz （ n = 14）. Its spectrogram is also multi-harmonic. The mimic mating call has three types： continuous 2 - 10 syllables and a longsyllable （two principal frequencies）, continuous 2 - 10 syllables （a principal frequency）, a long syllable （a principal frequency）. The main frequency range is 328 _ 18.2 Hz - 2 067 ± 189.1 Hz （ n = 38） . Its spectrogram is multi-harmonic with frequency bands of line structure or descending with time. The amplitude of the scaring call is the greatest. There are many pulses in each call. The main frequency range is 375 - 2 300 Hz. Its spectrogram is multi-harmonic with a line structure in low frequency harmonics and half-arched structure in high frequency harmonics .
