In this study, we describe the acoustic structure of ultrasonic alarm calls of Mongolian gerbils Meriones unguiculatus in the wild and verify these calls as belonging to Mongolian gerbils by comparison of their acoustic parameters with alarm calls recorded in captivity. Both in captivity and in the wild, the alarm calls of Mongolian gerbils represe...

Wild cheetahs Acinonyx jubatus of all age classes, from newborns to adults, use their long-distance chirps for communication with conspecifics. We investigated the ontogenetic changes of eight acoustic parameters of the chirps produced by wild-living cheetahs across 14 age classes in Kenya. Chirp maximum fundamental frequency (f0max) was found to b...

Adult cheetahs (Acinonyx jubatus) use long‐distance chirps for calling toward coalition partners (males), mates (both sexes), and cubs (females). Previously, these vocalizations were only investigated in captivity. This study estimates individual and sex‐related acoustic variation of the long‐distance chirps of 20 mature cheetahs (eight males and 1...

This is a practical guide for applying modern methods and approaches for measuring and analysis of the acoustic parameters in mammal and bird calls, along to principles of their recording in the field or under laboratory conditions. This guide contains a few practical tasks for call measuring and the comparative analysis of their acoustic variation...

The crested auklet is a medium-sized planktivorous seabird of the Alcidae family with complex social behavior, one of the interesting forms of which is the formation of club pairs in addition to existing breeding pairs. The occurrence of club pairs in this species was studied on the Talan Island (Sea of Okhotsk) in 1988-1989, when the colony was in...

Comparative studies of the communicative behavior of colonial nonpasserine birds are important for understanding the evolution of birds' social behavior. It is important to study in detail the behavior of particular species to accumulate data for such comparisons. The aim of this work is to describe the behavioral repertoire on the colony surface a...

Potential of ultrasonic vocalizations (USVs) to reflect a degree of discomfort of a caller is mostly investigated in laboratory rats and mice but poorly known in other rodents. We examined 36 (19 male, 17 female) adult yellow steppe lemmings Eolagurus luteus for presence of USVs during 8-min experimental trials including 2-min test stages of increa...

This study discovered a novel acoustic phenotype in Calsyntenin2 deficient knockout (Clstn2-KO) pups in the neurodevelopment period of 5-9 postnatal days (PND 5-9). The narrowband ultrasonic calls (nUSVs) were less complex (mostly one-note, shorter in duration and higher in peak frequency) in Clsnt2-KO than in wild-type (WT) C57BL/6 J pups. The wid...

Сбор сведений о биологии морских птиц обычно происходит в локальных гнездовых поселениях в течение относительно небольших промежутков времени. Однако меняющиеся условия среды или текущее демографическое состояние конкретной популяции могут оказывать существенное влияние на поведение особей тех или иных видов, что становится заметным при долговремен...

Vocal-based monitoring is increasingly being used as a non-invasive method for identifying individuals within avian populations and is promising for the Siberian Crane, Leucogeranus leucogeranus. This is a poorly studied, long-lived, secretive and critically endangered bird species that breeds in the Arctic tundra of western and eastern regions of...

Vocal development of cranes (Gruidae) has attracted scientific interest due to its special stage, voice breaking. During voice breaking, chicks of different crane species produce calls with two fundamental frequencies that correspond to those in adult low-frequency and juvenile high-frequency vocalizations. However, triggers that affect voice break...

Objectives: This is the first study of the sonic and ultrasonic vocalization in a Dipodidae rodent. For the small-sized quadrupedal northern birch mouse Sicista betulina, phylogenetically related to the bipedal jerboas (Dipodidae), we report null results for ultrasonic vocalization and investigate the acoustic cues to individual identity, sex and...

Сравнительные исследования коммуникативного поведения колониальных неворобьиных птиц важны для понимания эволюции социального поведения птиц в целом. При накоплении материала для подобных сравнений важны детальные исследования поведения отдельных видов. Цель данной работы – описание репертуара поведения на поверхности колонии, а также исследование...

Chicks can convey information about their needs with calls. But it is still unknown if there are any universal need indicators in chick vocalizations. Previous studies have shown that in some species vocal activity and/or temporal-frequency variables of calls are related to the chick state, whereas other studies did not confirm it. Here, we tested...

Despite a great number of empirical studies, the mechanisms of population differentiation and the factors that influence this process, particularly in seabirds, remain insufficiently understood. Here we analyzed population structure in the whiskered auklet (Aethia pygmaea), a previously poorly studied alcid species with unusual differentiation in c...

The works on the comparison of social behavior of nonpasserine birds are rather rare; however, they are useful for insight into the general theoretical issues, such as the evolution of birds’ social behavior. The aim of this work is the quantitative comparison of the birds’ behavior on the colony surface and its dependency on different factors such...

Zoo and wildlife management faces a problem with bird sexing, as many bird taxa have indiscernible gender differences in size and coloration. Problematic groups are geese, cranes, rails, raptors, owls, parrots, doves, auks, shearwaters and some passerines. Commonly accepted invasive sexing techniques based on genetics, laparoscopy, morphometric and...

Begging behaviour is an important element in the parent-offspring conflict; it has been studied in many avian species. However, the majority of the studies have been entirely based on the call counts, and they agreed that vocal activity was a good indicator of chick's nutritional need and/or condition. Fewer researches were dedicated to the tempora...

The effect of philopatry on the formation of the intrapopulation structure in the crested auklet colony of the Talan Island, Tauiskaya Bay of the Sea of Okhotsk, was examined. The nucleotide sequences of the mitochondrial DNA control region fragment (408 bp) and five microsatellite loci (Apy03, Apy04, Apy06, Apy07, Apy10) in individuals from two st...

Vocal individuality provides a method of personalization for multiple avian species. However, expression of individual vocal features depends on necessity of recognition. Here we focused on chick vocalizations of demoiselle, Siberian and red-crowned cranes that differ by their body size, developmental rates and some ecological traits. Cranes are te...

Chicks can convey information about their needs in food through their calls. However, it is still unclear if there are any universal acoustic markers of chick’s hunger. Here we tested experimentally whether acoustic call variables of human�raised Siberian crane chicks (Grus leucogeranus) are related to their hunger level. All measured frequency par...

The study of population differentiation is essential for understanding species evolution and ecology. Despite a large amount of published works in this area of study, the prediction of population structure in a number of animal species and, particularly, in seabirds remains difficult. The Crested Auklet (Aethia cristatella) is a small, planktivorou...

The vocal development of cranes (Gruidae) has attracted scientific interest due to a special stage, so-called voice breaking. During voice breaking, chicks produce both adult low-frequency and juvenile high-frequency vocalizations. The triggers that affect voice breaking are unknown. For the first time, we study the vocal development of the Demoise...

Birds that do not possess vocal learning exhibit contrasting styles of vocal development. For some Anseriformes, Galliformes and Charadrii species, gradual changes of call-frequency variables throughout development have been reported, while for some Gruiformes, Procellariiformes and Coraciiformes species, the changes are jump-like. The distribution...

Crested and parakeet auklets (Aethia cristatella and Cyclorhynchus psitaculla) are closely related plankton� feeding auk species that usually have complex social communicative behavior during breeding seasons. They differ to a great extent by the breeding density and development of sexual dimorphism in external features. The indicators of individua...

Crested auklet is a unique representative of the family Alcidae with a complex social behavior nesting in dense colonies with a size of up to one million individuals. Here we study specific individual features in their trumpet calls, loud vocalizations used by auklets as an advertising display. In 2008 and 2009, we recorded 231 calls of 24 individu...

It is usually assumed that individual recognition between parents and chicks develops when and where it is needed to restrict parental care to bird’s own offspring. Here, we tested this hypothesis on four related colonial seabird species of auks (Alcidae) that differ strongly in their nestling strategies. The first three studied species, the creste...

Vocal plasticity due to changes of social context is well documented in passerine birds. In other bird species, the impact of social environment changes on the whole vocal structure and on individual specific signatures remains largely unexplored. Here, we assessed inter- and intra-season stability of specific features of individual signatures in a...

Indicators of individual quality in ornamentation or in vocalizations have been reported for different animal species. However, no studies have jointly investigated ornamentation and vocalizations in one species. The crested auklet (Aethia cristatella, Alcidae) is a small colonial seabird of the North Pacific and is unusual for a bird in using opti...

The crested auklet, a highly social planktivorous bird species of the Northern Pacific, is an important component of marine ecosystems. Although visual and acoustic modalities play a major role in the communication of these birds, the available data on the repertoire of their vocal signals and postures are scarce and lack quantitative analysis. Thi...

Using to analysis of hypervariable fragment polymorphism in the control region of mitochondrial DNA(268 bp), the genetic variability of Swan goose Anser cygnoides L., included in the first category of endangered species in the Russian Red Book, has been investigated. Samples from the two main groups nesting in Russia—the Far Eastern group (Khabarov...

Voice breaking is a process associated with puberty of human males that also occurs in adolescence in some birds. This study reports the jump-like vocal changes occurring during voice breaking in adolescent red-crowned cranes (Grus japonensis). We investigated acoustic parameters of chirp and trill calls during vocal ontogenesis from hatching to th...

Here we present an acoustic approach for reliable sexing in four whistling duck species from the genus Dendrocygna and compare it with molecular and cloacal inspection techniques. In the four examined species, the White-faced Whistling Duck D. viduata, Fulvous Whistling Duck D. bicolor, Cuban Whistling Duck D. arborea and Red-billed Whistling Duck...

Acoustic-based monitoring has proved useful for many birds and seems promising for the endangered red-crowned crane. However, its validity in crane conservation is unclear in the absence of knowledge concerning the long-term stability of pair-specific duets. The red-crowned crane is monogamous and long-lived, with stable pair bonding both within an...

Distinctiveness of chicks’ calls may arise in ontogenesis when parents can confuse their own and alien chicks, leaving their nests and forming crèches or flocks. It is unknown, however, whether the individual vocal signature retains further in ontogenesis or relaxes when the necessity in the parental care disappears. In this paper, we study the int...

Individual, sexual, and related differences in chirp calls of 14 red-crowned crane chicks were analyzed for each of three age periods covering both family-territorial and flock stages of the development of chicks. The calls were recorded at the Oka Crane Breeding Center of the Oka Biosphere State Nature Reserve in the summer-autumn periods of 2003–...

Duets, specifically coordinated call series of pair mates, occur in all crane species. Here we compare the Red-crowned Crane duets from the mainland and the island geographical populations, and compare the duets from wild and captive mainland cranes of this species. In total, we analyzed 59 duets: 23 from wild island pairs, 20 from wild mainland po...

Here we compare the Red-crowned Crane duets from the mainland and the island geographical populations, and compare the duets from wild and captive mainland cranes of this species. In total, we analyzed 59 duets: 23 from wild island pairs, 20 from wild mainland po...

We studied the acoustic features of the endangered red-crowned crane (Grus japonensis), and, specifically, whether or not the duets carry information about a mating pair identity. The population of this species in the wild is only approximately 2,000 individuals. In 2003–2006, we recorded 343 duets from eight captive and two wild pairs. All of the...

Most studies on avian vocal ontogenesis have focused on taxa exhibiting some kind of vocal learning. This study provides a detailed analysis of vocal processes through early and late ontogenesis in 17 chicks of the Red crowned Crane Grus japonensis, a species lacking vocal learning. Three basic structural classes: trills, PE-chirps and PS-chirps an...

The White-faced Whistling Duck is a waterfowl species lacking any differences in ornamentation, coloration, size or behavior between the sexes. For distant communication, this species uses loud whistles. We analyzed 12 spectral parameters of 344 whistles from 23 captive adult ducks (14 males and 9 females). Discriminant analysis showed 94% correct...
