摘要
作者于2005年4-6月在四川老君山自然保护区,通过计算机声谱分析技术和回放技术,对四川山鹧鸪育雏期(Arborophila rufipectus)幼体的鸣声行为特征进行了研究,其结果表明,幼体有取食、警戒、惊恐和呼唤等4种不同行为的鸣声.取食鸣声和警戒鸣声均为单音节,它们的音节持续时间和主峰值差异显著.两种惊恐鸣声和四种呼唤鸣声的MPF和音节间隔时间差异性不明显,而音节持续时间差异极显著.
The chick vocal behaviors of the Sichuan partridges(Arborophila rufipectus) were studied in Pingshan County,Sichuan Laojunshan Nature Reserve with spectrographic analysis from April to June in 2005.Based on observation in the wild and playback experiments,the behaviors and characteristics of vocalization of the chicks of Sichuan partridge were analyzed.The results showed that chicks produced foraging call,alarming call,affrighting call and internuncial call during the post-incubation period.Both foraging call and alarming call were one-syllabled call.The duration of syllable and MPF of foraging call differed remarkabily from that of alarming call.Differences in MPF and interval time between the two affrighting calls and among the four internuncial had no significant,but duration of syllable between the two affrighting calls had significant difference.
