杂色山雀体型、子代性别比与鸣唱特征的相关性研究

鸣声在鸣鸟的生活史中具有重要作用,是其与外界进行信息交流最有效的方式之一。鸟类的鸣唱与其个体因素(如体型、子代性别比等)有着十分重要的联系。为了揭示个体体型、子代性别比与鸣唱特征之间的相关性,于2014—2015年3—6月在辽宁省仙人洞国家级自然保护区对杂色山雀指名亚种Parus varius varius的鸣声进行录制,测量了各体型参数,并对每巢雏鸟进行性别鉴定。结果显示:(1)杂色山雀体型与其鸣唱的最高频率具有显著相关性,但单一体型参数(体质量、跗蹠长度)与其鸣声参数相关性均不显著;(2)鸣唱语句长度与子代性别比具有显著相关性,子代性别比与其他鸣声参数均不存在显著相关性。本研究结果有助于进一步了解小型鸟类体型与鸣唱的关系,以及鸣唱与子代性别比之间的关系。     

金翅雀对城市噪音的非预期鸣唱响应模式

城镇化提高了环境噪音水平,一般认为高水平的噪音对城市鸟类鸣声的传播会带来不利影响。城市鸟类可以通过提高最低频率、增加鸣唱长度和缩短鸣唱的起始音素长度等不同的响应模式调节其鸣唱特征以实现鸣唱的有效传播。本研究采用Avisoft SASLab Pro比较了西宁市3个不同噪音水平下,金翅雀Chloris sinica的鸣唱特征(最高频率、最低频率、频宽、主峰频率、鸣唱时间和起始音素时间)的差异,以探索鸟类对梯度噪音水平的响应模式。结果表明,随着噪音水平的升高,鸣唱的最低频率和最高频率呈现出高-低-高的变化模式,鸣唱时间和起始音素时间呈现出短-长-短的变化模式;高、低噪音组内不同地点的鸣唱主峰频率差异显著(P<0.05)。结合鸣唱地点的植被特征,推测金翅雀在提高鸣唱频率避免被噪音掩蔽和降低频率以利于在林间传播之间可能存在一个权衡,鸣唱频率和鸣唱长度可能存在一定的关联,而主峰频率对噪音外的其他环境因子更敏感。     

白头鹎鸣唱特征的季节差异分析

许多动物的声通讯行为存在显著的季节变化,鸟类的鸣唱也是如此。雄鸟鸣唱具有宣告领域和吸引配偶的功能,在繁殖季节与非繁殖季节之间应存在一定差异,但差异如何？具体表现在哪些方面？这在很多鸟类中尚未可知。本研究以一种在秋季也有显著鸣唱行为的城市常见小型鸣禽——白头鹎（Pycnonotussinensis）为研究对象,比较其在春季（繁殖季）与秋季（非繁殖季）的鸣唱差异,并分析可能的原因。于2020至2021连续两年的春、秋季分别在武汉地区各采集了27只和30只雄性白头鹎的鸣唱录音,共测量分析春季鸣唱372个,秋季鸣唱435个。对测得的各鸣唱参数数据进行季节间比较,结果显示,白头鹎的鸣唱持续时间和鸣唱音节数存在显著季节差异,春季鸣唱的持续时间较秋季更长,鸣唱音节数更多。鸣唱的频率、能量分布等其他声学参数,以及鸣唱型出现率（反映鸣唱曲目大小）均未表现出显著季节差异。白头鹎鸣唱的时程特征相对其他鸣声特征更具季节可塑性。此外,还发现同一采样点的白头鹎春、秋两季使用相同的鸣唱型。本研究结果表明,春季白头鹎的单位时间鸣唱输出量更大,鸣唱行为更活跃,这与繁殖季节鸟类的领域性更强、为繁殖成功投入更多相一致。白头...     

青海西宁大山雀的鸣唱模式分析

2012年4~5月在西宁市录制大山雀的鸣声,用Avisoft-SASLab Pro声音分析软件分析其鸣唱结构。已有的录音记录分析表明西宁大山雀个体拥有1~4种鸣唱型,鸣唱短语由1~5个音素构成。西宁大山雀2音素短语的长度低于低海拔地区,具有较快的鸣唱型转换频率。     

武汉地区大山雀（Parus major minor）对major与minor亚种组鸣唱回放的差别反应

分析鸟类鸣声能为研究鸟类系统学和生物地理学提供重要信息。鸟类鸣声的地理变异能影响鸟类的性选择,进而导致不同地理种群间的生殖隔离,从而促进地方种群(或亚种)的分化,乃至新种的形成。在鸟类系统学研究中,鸣声回放实验是研究物种分化并衡量分类地位的一项重要研究手段。本实验以武汉地区大山雀(Parus major minor,隶属于minor亚种组)为实验对象进行鸣唱回放实验,观测其对来自欧亚大陆西部及北部各地的major亚种组和来自我国各地的minor亚种组大山雀鸣唱回放的反应,探讨实验对象能否区分来自上述两个不同亚种组的鸣唱,从而推断两亚种组之间是否存在足以导致识别障碍的鸣声分化,以致产生行为上的生殖隔离。本实验共测试了24只雄性大山雀,每个亚种组的鸣唱各回放给12只个体,通过记录不同行为反应指标来衡量每只受试个体的反应程度。统计分析结果显示,受试大山雀对major和minor亚种组鸣唱的反应有显著差异,对同为minor亚种组的鸣唱反应程度激烈,而对major亚种组鸣唱的反应微弱甚至大多无反应。由此认为,大山雀major和minor亚种组之间存在显著的鸣声分化,已达到能形成配对前生殖隔离的程度,从而一定程度上支持将大山雀拆分成不同种的说法。     

山地隔离和空间距离对高黎贡山灰腹地莺(Tesia cyaniventer)鸣唱特征的影响

鸟类鸣唱存在广泛的地理变异，研究鸟类鸣唱变异的模式及其影响因素可帮助解释自然界中广泛而复杂的鸣声变异现象。灰腹地莺（Tesia cyaniventer）是在高黎贡山海拔2000-2800 m分布的小型地栖性森林鸟类。高黎贡山南北走向的山脊海拔通常在3000m以上，这导致灰腹地莺东、西坡种群被山脊所隔离。该种小鸟鸣声洪亮易于鉴别，其鸣声地理变异可揭示山地对鸟类种群产生的隔离效应。在高黎贡山片马垭口和独龙江垭口的东西坡4个地点录制了灰腹地莺的鸣声（n=58），基于声谱分析比较了种群间鸣唱的质量特征，发现种群间鸣唱型的共享程度极低，而音节型在4个种群间均有共享。进一步测量了11个鸣唱的数量特征参数，有6个参数在不同种群间有显著差异：最低频率、中心频率、频率宽度、起始音节频率、首二音节的时间间隔、句子平均音节数。种群间的两两比较表明，鸣声特征差异呈现"隔离-距离"共同作用的格局，但隔离的影响更大。研究表明山地系统中影响鸟类鸣声地理变异的因素较为复杂，山地隔离和空间距离均对灰腹地莺的鸣唱特征产生了影响。     

河北塞罕坝褐柳莺繁殖期鸣唱变化

2017年5至8月,在河北省塞罕坝录制了80只繁殖期雄性褐柳莺(Phylloscopusfuscatus)的鸣唱,对其鸣唱句型和句子参数以及音节类型的变化进行了定量分析。褐柳莺鸣唱的两种主要句型——S-song和V-song,前者(F_(3,75)=17.983,P 0.05)和后者(F_(3,75)=17.983,P 0.05)的使用频次在不同月份间均存在显著差异。S-song的使用频次多于V-song的使用频次,且二者在繁殖季的变化表现出相反的趋势:S-song使用频次在5月和8月较高,在6月最低;而V-song的使用频次却是在6月达到最高值,在5月和8月较低。不同月份鸣唱句子最高频率(F_(3,75)=4.841,P 0.05)、句子频宽(F_(3,75)=3.814,P 0.05)和句子峰频率(F_(3,75)=3.793,P 0.05)均存在显著差异。通过80只个体的2 400个鸣唱语句得到了65种音节类型,其中,80%以上的音节类型在每个月中均有分布,但每月音节类型数存在显著差异(F_(3,75)=5.456,P 0.05)。音节类型数量随繁殖季的变化表现为,7月褐柳莺鸣唱中具有最多的音节类型数(19.79±3.69),5月和8月音节类型数较少,8月最少。     

两种斑鸠核型的比较分析

本文比较分析的珠颈斑鸠和山斑鸠的核型2n=80±,AN=92±,均具有典型的鸟(?)两型性核型。但珠颈斑鸠No.3和7分别为亚端部和端部着丝点染色体,而山斑鸠的这两号染色体则为端部和亚中部着丝点,珠颈斑鸠核型中含端部或亚端部着丝点染色体比山斑鸠多一对,可见这两个近缘种的核型已具有明显的种性差异。根据鸟类核型演化的一般规律,珠颈斑鸠似乎较为原始,而山斑鸠则相对较特化。     

中国大杜鹃的鸣声

一直以来认为广布欧洲大陆和亚洲大陆的大杜鹃 ,其鸣声在地区之间无差异 ,而分布在亚洲的大杜鹃的鸣声至今未有系统的研究报道。本文以分布在中国北部的大杜鹃指名亚种和新疆亚种的广告鸣叫为主要研究对象 ,将其与在四川和云南省分布的大杜鹃华西亚种以及分布在朝鲜、日本、俄罗斯和英格兰的大杜鹃指名亚种的广告鸣叫进行了初步比较。在中国分布的大杜鹃有五种鸣叫类型。中国所有采集地大杜鹃的广告鸣叫都由两个音节组成 ,并且与英国分布种群的广告鸣叫很相似。各地大杜鹃的领域鸣唱呈现出个体质的高度保守性和数量性状的明显差异     

棕眉柳莺鸣唱声谱分析及其地理差异的初步研究

2002、2005、2007年5-8月,在甘肃莲花山、宁夏贺兰山和内蒙阿拉善贺兰山等自然保护区对棕眉柳莺(Phylloscopus armandii)的鸣唱进行了采集,共录到18只108 min的鸣声.通过声谱分析,棕眉柳莺鸣唱的频率范围在2.63-6.32 kHz之间;音素数平均为5.56±2.47(n=124);持续时间为(1.07 4-0.30)s(rg=124).最长可达2.68 s.棕眉柳莺鸣唱音节之间的间隔时间差异较大,范围在2～18 8之间;从18只个体共589个音节中总结出61种音节类型,其中37种为共享音节,24种为特有音节,分别占总数的60.7%和39.3%.不同棕眉柳莺个体的鸣唱音节类型组成不同,没有任何两只棕眉柳莺个体的音节曲目完全一致.莲花山和内蒙贺兰山两个地区内个体之间的音节相似性系数存在显著差异(P=0.001).通过对棕眉柳莺鸣唱的地理变异分析,发现越是邻近分布的个体其鸣唱也越相似.     

Responses of a sub-oscine bird during playback: effects of different song variants and breeding period

Vermilion flycatchers (Pyrocephalus rubinus) vary their song rate and song length across the breeding season. Males sing more and longer songs after nest construction than before. Here we explored the possibility that this variation is meaningful to territorial males. Using a playback approach, we tested several males with different variations in song output (i.e. variations in song length and song rate) in different periods of the breeding season (i.e. before and after the onset of nest construction). We found that males call more in response to playbacks of long and short songs before the onset of nest construction. However, after nest construction began they responded flying more when exposed to long songs than to short songs. These results show that vermilion flycatcher discriminates between different variants of song length, and suggest that males react to long songs as if they were more threatening signals than short songs, especially after the onset of nest construction. We did not find evidence of males discriminating between a high and a low song rate. We discuss some possible implications for song function in this sub-oscine species, and compare these findings with other results in oscine species.     

Duetting behavior in a Neotropical ovenbird: sexual and seasonal variation and adaptive signaling functions

Duetting is a collective behavior and might have multiple functions, including joint territory defense and mate guarding. An important step toward understanding the adaptive function of bird song is to determine if and how singing behavior varies seasonally. However, seasonal patterns for duetting species are different from the pattern described for species in which only the male sings, because song function may vary according to sex, singing role (initiator vs responder) and level of duet organization (individual vs pair). We investigated whether patterns of seasonal variation in duetting depends on these factors, which would suggest different interpretations of song function. We studied social pairs of a Neotropical bird species (rufous hornero Furnarius rufus) for seven consecutive months, recording vocal and territorial behaviors. Overall, partners coordinated 61% of their songs into duets and many song traits (song initiation rate, song output and duet rate) peaked in territorial contexts. Males engaged in territorial interactions with strangers more often, initiated more songs, and answered proportionately more of their partners’ songs than females. Male song initiation rate peaked during the pre‐ and post‐breeding stages, whereas females initiated more songs during the non‐breeding season. Both sexes answered partner songs faster and at higher rates during the pre‐breeding and female fertile stages. Partners duetted at a higher rate during the pre‐ and post‐breeding stages. Finally, song initiation rates and duet rate, but not song answering rates, correlated with frequency of territorial interactions with strangers. Although our findings indicate that song function may vary with sex, singing role and level of duet organization, our results suggest that in general duet functions to defend common territories and as a mutual mate guarding strategy in the rufous hornero.     

Ecological and Phylogenetic Effects on Song Sharing in Songbirds

As a consequence of vocal learning, the songs of male songbirds often vary geographically. We examined three proximate hypotheses that predict variation in the incidence of local song sharing among species: the annual cycle, breeding season duration, and epiphenomenon hypotheses. To test these hypotheses, we compiled data from the literature on local song sharing, annual cycle, breeding location isophane (an index of breeding season duration), repertoire size, and phylogenetic relationships of 65 populations in the family Fringillidae. Mapping characters on the phylogenetic tree revealed that local song sharing, migratory status, and breeding location isophane were randomly distributed on the phylogeny. Breeding isophane and migratory status were themselves correlated and had significant effects on the probability of sharing local songs. As predicted by the annual cycle and breeding season duration hypotheses, males in sedentary populations and populations breeding at low isophanes were more likely to share local songs. In subsets of the data, the annual cycle hypothesis received more support than did the breeding season duration hypothesis. Neither hypothesis explained more than 17% of the variation in the incidence of song sharing, and we suggest that detailed information on song function, male dispersal, and constraints on the timing of song learning will be needed to better predict the occurrence of local song sharing.     

Territory establishment,song learning strategies and survival in song sparrows

In most songbirds, the processes of song learning and territory establishment overlap in the early life and a young bird usually winds up with songs matching those of his territorial neighbors in his first breeding season. In the present study, we examined the relationships among the timing of territory establishment, the pattern of song learning and territorial success in a sedentary population of song sparrows (Melospiza melodia). Males in this population tend to learn their songs from their neighbors and consequently they show high song sharing with neighbors and use these shared songs preferentially in interactions with them. Males also show significant variation in the timing of territory establishment, ranging from their natal summer to the next spring. Using a three-year dataset, we found that the timing of territory establishment did not systematically affect the composition of the song repertoire of the tutee: early establishers and late establishers learned equally as much from their primary tutors and had a similar number of tutors and similar repertoire sizes, nor did timing of territory establishment affect subsequent survival on territory. Therefore, the song-learning program of song sparrows seems versatile enough to lead to high song sharing even for birds that establish territories relatively late.     

白头鹎繁殖期鸣声行为的研究

利用计算机鸣声分析技术对白头鹎繁殖期的求偶炫耀鸣唱、晨鸣、遇险告警惊叫等鸣声的特征进行分析，以探讨鸣声特征与行为的关系。白头鹎繁殖前期待有的求偶炫耀鸣唱婉转多变，频率一般变化在１．９－３．５ｋＨｚ之间，另一类出现在繁殖前、中期的炫耀鸣唱急促而响亮，音节变化快且频率高（变化范围约３．４－４．４ｋＨｚ）；最鸣和繁殖期特有的其它鸣声，音节清晰，响度较大，能量主要集中在２－３ｋＨｚ之间，可能具有宣告领域的     

Female song sparrow, Melospiza melodia, response to simulated conspecific and heterospecific intrusion across three seasons

To investigate female responses to territorial intrusion I presented female song sparrows with either a simulated female song sparrow intrusion or a simulated spotted towhee, Pipilo maculatus, intrusion as a control during either the prebreeding, breeding or postmoult seasons. Aggressive and nonaggressive behaviours and vocalizations were compared between intrusion types and across seasons. Principle components analysis suggested that female responses fell into three categories: (1) responses directed towards the intruder, mostly aggressive; (2) responses directed towards the mate; and (3) lack of response to the intruder. In every season, females responded more aggressively to simulated female song sparrow intrusion than simulated towhee intrusion. Responses directed towards female song sparrow intruders dropped across the three seasons and were significantly higher in the prebreeding season than in the breeding or postmoult seasons.

丹顶鹤性活动的声行为研究

丹顶鹤繁殖期的性活动可分为雄鹤求偶、雌鹤对雄性求偶的应答、两性交配和交配完结4个阶段,其相应的鸣声模式分别为雄性的求偶鸣声、雌性对雄性求偶的应答声和两性的对鸣声、两性对唱的交配声和两性的高声合唱。4个阶段鸣声都是以基本音的主频率(PF)为主音的单音调声,前3个阶段都带数个近似fn=nf0(f0=FP)关系的低幅值谐频成分。第4个阶段带数个近似fn=nf0(f0=FP)关系的高幅值谐频成分;品质因数(Q3dB)多半为4～6,声脉冲重复频率(RFP)一般为150～180Hz,而第2阶段声的RFP一般为180～260Hz。雄性鸣声的每个单次叫声中含有的音节数较少,一般不超过4个;而雌性鸣声比较复杂。每个单次叫声中含有的音节数较多,一般都在7～8个以上;但雌雄鸣声的每个音节都是由3个声脉冲组成。雄鹤鸣唱声频率变化范围较小,而雌鹤鸣唱声频率变化形式是由低到高达到高峰后又开始下降。4个阶段的鸣声都具有较好共鸣。只有第2阶段发声运动较快。而且发现雄鹤鸣唱单次鸣叫声的音节数“增多”。各阶段鸣声特性均存在差异,不同配偶间均存在显著差异,研究结果表明丹顶鹤雌雄都具有不同的鸣声,且其性活动过程中不同的鸣声行为具有较高的个体识别信号潜能。另外,求偶鸣叫声和求偶应答与对鸣声在性活动鸣声中起着决定性的作用。     

Territorial song and song neighbourhoods in the Scarlet Rosefinch Carpodacus erythrinus

Throughout the range of the Scarlet Rosefinch, its territorial song consists of 3–9 (usually 4–5) elements, of which there are 5 different types. The differences lie in the way the pitch of the element changes in time (frequency "slope") and the width of the frequency band. Within a given type of song, the various elements can be present in almost any combination. Therefore, so many song types can be formed that the songs in even small parts of the species' area are clearly distinct from one another. Despite this capacity for variation, however, by chance identical songs may be sung in widely separated parts of the area, in some cases by different subspecies.
The species has not developed large-scale dialects or regiolects based on a song tradition acquired during an early imprinting phase. Scarlet Rosefinches tend to breed in small colonies, groups of up to about 15 pairs characterized by the same type of song (song neighbourhoods, formed by the development of a microlect).
Microlects develop by a founder effect. When males, near one-year old or older, join one another to form isolated colonies after arrival in the breeding region, they adopt ("learn") the song type that will eventually characterize the colony from the first male to arrive at the site. After the colony has been founded, in most cases each male uses only one type of song during a breeding season, with practically no variation of the temporal and frequency parameters.
Singing the same type of song, the members of a colony accept one another sufficiently to allow the breeding territories to be closely packed. It appears that a long-lasting capacity for acoustic learning, in combination with colony-like breeding and great ecological flexibility, has allowed the Scarlet Rosefinch to become the most successful species of the genus Carpodacus .     

Song dialects,mate selection,and breeding success in white-crowned sparrows

The songs of 15 colour-marked, mated pairs of white-crowned sparrows (Zonotrichia leucophrys nuttalli) were recorded in a contact zone between the Presidio and San Francisco, California dialect regions. Males were recorded in the field and females were trapped after the breeding season and injected with testosterone to induce singing. The song of each member of a mated pair was classified using two different markers. It was found that most pairs did not match song types, and that the reproductive success of those that matched did not differ from those that did not match. Most of the territorial males sang the Presidio dialect, while most injected females sang the San Francisco dialect. The results fail to support a positive assortative mating hypothesis regarding the functional significance of learning dialects. It is suggested that the mismatching of songs could be due to sexual differences in the disposition to learn songs of neighbours at the breeding site.     

纯色山鹪莺的领域鸣叫

鸟类鸣叫是鸟类行为研究的一项重要内容,为探究纯色山鹪莺(Prinia inornata)的鸣叫模式与其尾羽逆向变化的关系,于2007年8-10月在广东省肇庆江溪村对繁殖期纯色山鹪莺的领域鸣声等行为进行研究。运用焦点动物观察法,通过Olympus DS-20数码录音笔(100—17100Hz)和直径50cm声音收集器采集声音。行为统计以直接观察和SonyDCR-VX2000E数码摄像机录像相结合。结果如下:⑴共采集到620个鸣句,分属6种鸣句类型,其中4中为常见类型,1种为过渡类型,1种少见类型。(2)纯色山鹪莺的鸣声结构简单,变化较多,能够根据环境改变鸣声,具有识别危险程度和危险对象种类的能力。(3)鸣声均和一定的行为具有联系,4种主要鸣声类型均伴有抖尾行为出现。据此认为,纯色山鹪莺鸣唱结构简单但变化较多,而尾羽在其领域鸣叫行为中发挥了一定作用。
