繁殖期黄喉Wu的领域鸣唱及其种内个体识别   总被引:5,自引:0,他引:5  
在镜泊湖自然保护区收录黄喉wu(Emberiza elegans)的鸣唱声,室内作出鸣唱的语图和声谱图。繁殖期黄喉wu领域鸣唱的频率范围2.4-6KHz,有13-28个音节,2-3泛音,鸣唱持续时间2.2-4.0秒;具有相似的频谱结构,但种内个体间亦存在差异。野外对比实验的结果可说明,黄喉wu有识别邻鸟和陌生鸟领域鸣唱的能力,有对声音的记忆和定位的能力。  相似文献

采用SDS-聚丙烯酰氨凝胶电泳法,对扎龙自然保护区6种雀形目鸟类(黄喉鹀、黄眉柳莺、黄胸鹀、虎纹伯劳、麻雀和灰头鹀)的4个血液蛋白位点[血红蛋白(Hb)、白蛋白(Alb)、转铁蛋白(Tf)和腺苷脱氨酶(Ada)]进行了多态性检测.结果表明:研究区6种鸟类在这4个血液蛋白位点上均存在多态性,这6种鸟在Ada座位上均表现出较大的遗传变异性;黄眉柳莺的群体遗传变异较大,灰头鹀的群体稳定性相对较高;这6种鸟可划分为两大类,黄喉鹀、黄胸鹀、灰头鹀和黄眉柳莺聚为一大类,麻雀和虎纹伯劳聚为另一类,这与6种雀形目鸟类的实际分类地位基本相符;研究区较高的体温调节价和取食压力并未导致6种鸟类血液蛋白的遗传结构产生较大变异,可能是由于该地区雀形目鸟类与外界存在一定的基因交流,从而缩减了其群体遗传上的变异和分化.  相似文献

鸟类环志是种群监测和迁徙研究的重要手段。基于秦皇岛鸟类环志站1999 ~ 2019年的环志数据,对黄胸鹀(Emberiza aureola)和蓝歌鸲(Larvivora cyane)两种鸟类在21年间的种群动态和迁徙时序进行了分析。结果表明,迁徙途经秦皇岛的黄胸鹀种群数量以4或5年为周期呈规律性的波动下降,年均降幅达17.3%,21年间种群数量累计下降了97.7%。近年来我国加强了对黄胸鹀及其栖息地的保护管理,并于2021年初将其列为国家I级重点保护动物,有望促进其种群的逐步恢复。蓝歌鸲种群数量的年均降幅为4.2%,但下降过程主要集中在1999至2003年间,其后种群指数趋于稳定。黄胸鹀春季网捕高峰短暂而集中,持续约15 d;秋季网捕高峰则较为分散,持续约47 d。这表明黄胸鹀春季迁徙进程明显较为集中和快速,可能是出于繁殖需求采取了时间最短的迁徙策略。蓝歌鸲成年雄鸟、成年雌鸟和亚成鸟春季的网捕高峰在日期上有明显的差异,间隔4或5 d先后出现,表明蓝歌鸲不同年龄和性别的个体在春季进行差别迁徙,有利于减小停歇地的种内竞争,并确保雄鸟提前到达繁殖地占领优质的繁殖领域。  相似文献

The degradation of bird sounds during long-range propagation depends on different parameters such as density of vegetation, height from the ground and atmospheric perturbations. We investigated whether the wren Troglodytes troglodytes, a bird species which has a high-pitched song that is very susceptible to degradation and lives in an environment that is very restricting for sound propagation, has any advantage in choosing relatively high song posts. Song degradation was investigated by analysing sound attenuation, duration of notes and silences, spectrum composition, modifications of frequency-modulated notes and amplitude fluctuations. Our data show that the choice of an elevated song post improves the reliability of all song parameters and increases the propagation distance of the song. It also improves the male wren's ability to hear opponent songs. The results are discussed from an ecological point of view.  相似文献

Adult males of the grasshopper Chorthippus biguttulus exhibit a stereotyped turning behaviour towards the direction of the female song. This behaviour has been used to study the regeneration of synaptic connections used for pattern recognition and sound localization. Unilaterally deafened animals are not able to localize the sound direction and turn exclusively towards the intact side, regardless of the speaker position. This behaviour does not change with postoperative time. After an axotomy of the tympanic nerve fibres the sensory axons regrow and regenerate their synaptic contacts which is deduced from the recovery of the ability to localize sound. The behavioural threshold for stimulation from the operated side is increased by approx. 5 dB SPL. The probability of correct turning towards the operated side increases with postoperative time. The ability for lateralization improves with postoperative time and may reach values of intact animals (discrimination of 1–2 dB SPL difference. Animals with two operations (axotomy of one tympanal nerve and blocking of the other ear) do not react to the female song, which suggests that recognition of the species-specific song pattern is not possible with the regenerated fibres and their synaptic connections alone. Neuroanatomical studies show that the regeneration of localization ability is correlated with an ingrowth of sensory fibres into the frontal auditory neuropil of the metathoracic ganglion.  相似文献

The cicada Okanagana rimosa (Say) has an acoustic communication system with three types of loud timbal sounds: (i) A calling song lasting several seconds to about 1 min which consists of a sequence of chirps at a repetition rate of 83 chirps per second. Each chirp of about 6 ms duration contains 4-5 pulses. The sound level of the calling song is 87-90 dB SPL at a distance of 15 cm. (ii) An amplitude modulated courtship song with increasing amplitude and repetition rate of chirps and pulses. (iii) A protest squawk with irregular chirp and pulse structure. The spectra of all three types are similar and show main energy peaks at 8-10 kHz. Only males sing, and calling song production is influenced by the songs of other males, resulting in an almost continuous sound in dense populations. In such populations, the calling songs overlap and the temporal structure of individual songs is obscured within the habitat. The calling song of the broadly sympatric, closely related species O. canadensis (Provander) is similar in frequency content, but distinct in the temporal pattern (24 chirps per second, 24 ms chirp duration, eight pulses per chirp) which is likely important for species separation in sympatric populations. The hearing threshold of the auditory nerve is similar for females and males of O. rimosa and most sensitive at 4-5 kHz. Experiments in the field show that female phonotaxis of O. rimosa depends on parameters of the calling song. Most females are attracted to calling song models with a 9 kHz carrier frequency (peak frequency of the calling song), but not to models with a 5 kHz carrier frequency (minimum hearing threshold). Phonotaxis depends on temporal parameters of the conspecific song, especially chirp repetition rate. Calling song production is influenced by environmental factors, and likelihood to sing increases with temperature and brightness of the sky. Correspondingly, females perform phonotaxis most often during sunny conditions with temperatures above 22 degrees C. Non-mated and mated females are attracted by the acoustic signals, and the percentage of mated females performing phonotaxis increases during the season.  相似文献

杭州鹊鸲的声行为   总被引:1,自引:0,他引:1  
姜仕仁 《四川动物》2003,22(3):144-146,F003
1996年8月至2002年7月,在杭州对鹊鸲的声行为进行了观察和记录,并以鸣声回放验证某些鸣声的功能。对求偶鸣唱、领域鸣唱、抗议鸣叫、嬉闹鸣叫、联络呼唤声和惊叫声等6种鸣声进行了分析,各具不同的声学特征。该鸟的鸣声结构非常复杂,由一系列不同类型的短语所组成,每个短语又有3~10个音素所构成。并将杭州与印度哈里瓦地区鹊鸲的领域鸣唱进行了比较,两地鹊鸲的鸣声特征很不相同。  相似文献

The crystallized structure of adult zebra finch (Taeniopygia guttata) song is modifiable if sensory feedback is altered during sound production. Such song plasticity has been studied by examining acoustic modifications to the motif; however, the underlying changes to the vocal motor patterns of these acoustic modifications have not been addressed. Adult birds in two age categories (young=90-120 days or middle aged 150-250 days) that sang crystallized song were used in the experiment. Vocal motor patterns were monitored by recording respiratory air sac pressure before, during, and after song plasticity was induced by partial or complete reduction of phonation (i.e., "partial muting"). Birds were recorded until changes in air sac pressure patterns underlying the song structure were observed (up to 160 days). Young adult birds were more likely to insert shorter duration (<125 ms) expiratory pulses (EPs) into the motif than middle-aged adults. These shorter duration EPs were produced with a unique pressure pattern relative to the intact song, and therefore appeared to be generated by novel motor gestures. Stuttering (atypical repetition of an EP) was observed when these novel EPs were inserted into the motif, regardless of age. The EP of the distance call, which is also a learned vocalization in zebra finches, showed a similar reduction in duration if EPs were also shortened in the song. The emergence of shorter duration EPs was not related to sound production, or nonspecific effects of the surgical procedure, which suggests an age-dependent neural process for song plasticity.  相似文献
