画眉科鸟类多为华南区(东洋界)固有的种类,而华南区又以云南省内发现的种类为最多,其次为广西、广东和福建;在华北区所产的种类最少。陕西省隶属于华北区(古北界),以往有纪录的有六属 Pomatorhinus,Pnoepyga,Garrulax,Spelaeornis,Alcippe和 Babax。在太白山北麓及渭河平原,最近三年内获得七种画眉鸟类,分隶三属:Pomato-rhinus,Garrulax和 Yuhina。其中 Yuhina是属于新纪录范畴。因此对于种类分佈,似有一定意义,依郑作新氏建议(1950),古北界与东洋界的分界线,在陕西省应以秦岭为准。就此种鸟类分佈而言,似更合理。这样,对于鸟类区划问题,可增多一些认识,特分述于下: 相似文献

Parasitism generally imposes costs on victims, yet many victims appear to tolerate their parasites. We suggest that in some cases this may be because parasites provide victims with mitigating benefits, paradoxically giving rise to selection for advertisement rather than concealment by parasites. We investigate this possibility using the interaction between an avian kleptoparasite, the fork-tailed drongo (Dicrurus adsimilis), and one of its victims, the pied babbler (Turdoides bicolor). Combining field observations and a playback experiment, we demonstrate that a conspicuous vocal signal broadcast by drongos perched waiting to steal food from foraging babblers allows the latter to improve their own foraging efficiency, although not to the same extent as that experienced in response to conspecific sentinel calling. We argue that "sentinel" calling by drongos may originally have arisen as a means of manipulating babblers: because babblers find more food items and venture into the open more in response to these vocalizations, drongos are presented with more kleptoparasitism opportunities. However, the resulting benefit to babblers could be sufficient to reduce selection for the evolution of defenses against drongos, and the current situation may represent a rare example of an interspecific relationship in transition from a parasitism to a mutualism. 相似文献

The phylogenetic relationships of the Timaliidae (babblers) and Sylviidae (warblers) have long challenged ornithologists. We focus here on three Malagasy genera currently assigned to the Timaliidae, Mystacornis, Oxylabes, and Neomixis, and on their relationships with other babblers and warblers using the sequences of two mitochondrial genes (cytochrome b and 16S rRNA). Maximum parsimony analyses show that the Malagasy "babblers" are not related to any of the other African and Asian babblers. The genus Mystacornis is neither a babbler nor a warbler. The other Malagasy "babblers" are members of warbler groups (the monophyly of the Sylviidae is not demonstrated). Oxylabes madagascariensis and Hartertula flavoviridis (we recognize Hartertula as a genus for the species flavoviridis, previously Neomixis flavoviridis) constitute, with two presumed sylviine taxa, Thamnornis chloropetoides and Cryptosylvicola randrianasoloi, a warbler radiation endemic to the island of Madagascar. The other Neomixis species (tenella, striatigula, and viridis) belong to another warbler group comprising cisticoline taxa. These results show that the Timaliidae did not disperse to Madagascar. Rather, the island has been colonized, independently, by at least two clades of warblers, probably originating from Africa, where the Sylviidae radiation has been the most extensive. 相似文献

The Asian scimitar babblers, including the genus Pomatorhinus and Xiphirhynchus, are a small group of babblers characterized by long down-curved bills and a distribution throughout East and Southeast Asia. To infer the molecular phylogeny of this group and their divergence time, we examined sequences of multiple fragments including two entire mitochondrial genes and four nuclear introns (4352 bp in total) from multiple samples of eight of the nine recognized species of Asian scimitar babblers. The phylogeny resulting from the concatenated multi-locus dataset suggests that Pomatorhinus is paraphyletic. Due to its paraphyly, we propose dividing the traditional genus Pomatorhinus into two morphologically and genetically diagnosable genera: Pomatorhinus and Erythrogenys. Results of the molecular dating based on the conventional mitochondrial DNA divergence rate indicates that the diversification of these babblers is likely congruent with the historical climatic events. Our findings shed light on the diversification of avian species in southern Asia, a poorly studied biodiversity hotspot. 相似文献

The Arabian babbler, Turdoides squamiceps, displays an unusual behaviour, the ‘morning-dance’. This article examines the influence of the presence and behaviour of an observer on the dance frequency. The results are the summary of more than 3 yr of study by 12 observers, who performed 1335 observations and witnessed 286 dances that took place among 15 groups of babblers. Different experiments were carried out on 148 additional mornings. Different observers witnessed different dance frequencies. Dance frequency witnessed by an observer decreased with observer's experience. Observers watching groups of babblers on single days witnessed more dances than those who watched the same groups for several consecutive days. Dance frequency was higher on the first day of a series of observations than on the following days in the same series. If a group of babblers remained unobserved for one day, the frequency of dancing increased. An evening observation considerably decreased the frequency of dancing the following morning. Feeding experiments did not elevate dance frequency. Experimental disturbance at the roost before dawn increased dance frequency while permanent disturbance and frightening experiments did not. Change in the observer's presence and behaviour caused the babblers to react by dancing. The hypothesis that the observer's presence and behaviour influences different group members differently, and therefore alters the relationships among them, is offered to explain the results that observers can affect the dance frequency. 相似文献

Sex biases in adult aggression have been well studied and commonly arise when resources which affect survival or lifetime reproductive success are less abundant or more valuable for individuals of one sex. Despite the prevalence of sex biases in adult aggression, evidence for sex biases in juvenile aggression is scant. Here, we present evidence for female‐biased juvenile aggression in cooperatively breeding pied babblers (Turdoides bicolor). Unlike most cases of non‐lethal sibling aggression, juvenile aggression in pied babblers does not seem to be determined by food availability. Instead, we found that juvenile aggression was related to adult dispersal patterns. This study shows that females that were more aggressive as juveniles attempted dispersal earlier than less aggressive females. Potential explanations for the association between juvenile aggression and adult dispersal patterns are discussed. 相似文献

Cooperatively breeding Arabian babblers (Turdoides squamiceps)
havea repertoire of different calls that they use in predator-induced
contexts.We investigated their vocal mobbing behavior in two different
predator-inducedsituations. We presented territorial groups of babblers a
perched,stuffed owl representing an avian predator and a cat representinga
ground predator. Babblers approached in both situations andmobbed the
predators with the same two call types. In both predator-inducedsituations
their first call was a short, metallic-sounding "tzwick."In
response to the cat, babblers continued to primarily usetzwicks. However, in
continued response to the owl, the babblersprimarily used long trills. The
experiments indicate that differencesin use of two common call types during
mobbing provide informationon differences in predator-induced situations,
although no calltype per se identified a specific situation. The experiments
suggestthat the short tzwicks indicate a higher risk or urgency thantrills
and that combinations of both call types may providegraded information about
differences in predator-induced situations.The relatively stable groups of
these cooperative breeders mighthave favored evolution for using different
calls in differentmobbing situations. 相似文献

DNA phylogenies have gradually shed light on the phylogenetic relationships of the large babbler group. We focus in this study on the family Leiothrichidae (laughingthrushes and “song babblers”), which represents the largest clade of babblers in terms of species diversity. Our phylogeny includes all genera and 82% of the recognized species, using mitochondrial and nuclear loci. The sister group to Leiothrichidae is composed of the Pellorneidae (“jungle babblers”) plus the genus Alcippe. Within Leiothrichidae, four strongly supported primary clades (A–D) are recovered. Clade A includes Grammatoptila, Laniellus and Cutia. Clade B includes a large group of laughingthrushes, all of them classified in Trochalopteron. In Clade C, the two laughingthrushes endemic to southern India, T. fairbanki and T. cachinnans, which have recently been proposed to be placed in the newly erected genus Montecincla, form a sister clade to the group comprising the “song babblers” (Lioptila, Leiothrix, Heterophasia, Minla, Liocichla, Actinodura, Chrysominla, Siva, and Sibia). Clade D includes the African babblers (Turdoides, Phyllanthus, Kupeornis), Asian relatives (Argya, Acanthoptila, Chatarrhaea) and all remaining laughingthrushes (Garrulax). The time estimates suggest that the early diversification of the Leiothrichidae occurred in the mid‐Miocene, a period that corresponds to the diversification of many passerine groups in Asia. A revised taxonomic classification of the family is proposed in the light of these results. 相似文献

In many cases of interspecific kleptoparasitism, hosts developdefensive behaviors to minimize the impact of kleptoparasites.Because vigilance and defensive behaviors are often costly,selection should favor hosts that adjust the amount of investmentneeded to minimize losses to kleptoparasitism. However, examplesof such facultative responses are rare. Here, we investigatethe response of cooperatively breeding pied babblers (Turdoidesbicolor) to the drongo (Dicrurus adsimilis), an avian kleptoparasitethat regularly follows pied babbler groups, often giving alarmcalls to alert the group to predators but also occasionallygiving false alarm calls in order to steal food items. We showthat pied babbler response to drongos varies markedly accordingto babbler group size. In small groups, where there are fewindividuals available to act as sentinels, babblers sentinelless when a drongo is present and respond strongly to drongoalarm calls. However, in large groups, where there are manyindividuals available to participate in predator vigilance,babblers sentinel more often when a drongo is present, rarelyrespond to drongo alarm calls, and aggressively displace drongos,with a consequent decline in the number of successful kleptoparasitismevents. This behavior represent a facultative response to akleptoparasite according to the costs versus benefits of toleratingtheir presence. 相似文献

The coexistence of numerous species within a community results from how those species use available resources. Babblers are one of the major groups of Malaysian insectivorous birds, which frequently forage in dense vegetation cover and have a high level of sympatry. Therefore, examining the diet, prey selection, and niche segregation of babblers can be challenging. In this study, we used high-throughput sequencing to investigate potential dietary overlap or segregation among 10 babbler species of the 4 genera of the family Pellorneidae and Timaliidae: Pellorneum, Malacopteron, Stachyris, and Cyanoderma in central peninsular Malaysia. We tested the hypothesis that trophically similar species may differ in resource use to avoid competitive exclusion. We identified 81 distinct arthropod taxa from fecal samples, belonging to 71 families representing 13 orders, which were predominantly from 16 dipteran, 13 lepidopteran, and 10 coleopteran families. Of all the prey taxa consumed, 45% were found to be distinct across the 10 babbler species, and ˂35% were shared simultaneously by ≥3 babbler species, indicating minimal dietary overlap. The black-throated babbler Stachyris nigricollis and moustached babbler Malacopteron magnirostre had the most generalist tendencies because they consumed a greater variety of prey taxa. Small dietary overlap values (Ojk) and a relatively wide range of food resources suggest that dietary segregation occurred among the studied babblers. The great diversity of prey consumed revealed the presence of dietary flexibility among the sympatric insectivorous birds, thus reducing any active dietary competition and facilitating the coexistence through niche partitioning. 相似文献

Birds scratch their heads in one only of two ways, either directly or indirectly, and one method is used by all members of the same family though not necessarily by all families in the same order. When related families have different head-scratching methods, then the behaviour can help in disentangling difficult relationships. Examples are given. In the case of the passerines, only the Timaliidae (babblers) scratch directly. The implications are briefly discussed; for example, on this evidence Picathartes is not a babbler. The Psittaciformes are a potentially rewarding group for future work. 相似文献
