ABSTRACT The Pectoral Sandpiper (Calidris melanotos) is one of a few highly polygynous shorebirds with strong sexual size dimorphism. The vocal part of the male courtship display has received some attention, but how the sound is generated is largely unknown. To fill this gap, we analyzed video and sound recordings collected on the breeding grounds at Barrow, Alaska, USA. The anatomy of 2 males was investigated by macroscopic and histological dissection. Synchronized wing movements and a closed… 
Song amplitude and population density in two sympatric warblers, Phylloscopus schwarzi and P. fuscatus
The analysis of video-recordings revealed the larger extension of the neck region (‘throat sac’) in Radde’s Warbler than in Dusky Warbler, which was hypothesised to be responsible for the louder song of Raddes Warbler.
Breeding site sampling across the Arctic by individual males of a polygynous shorebird
It is shown that most males of a migratory, polygynous shorebird that arrived at a known breeding location in northern Alaska subsequently moved through a considerable part of the entire species’ breeding range, sampling as many as 23 additional potential breeding sites.
Previously unknown behavior in parasitic cuckoo females: male-like vocalization during migratory activity
It is found for the first time that Oriental Cuckoo females can produce male-like calls in that time, and this findings may shed light on the evolution of vocal communication in avian brood parasites.
Coos, booms, and hoots: The evolution of closed‐mouth vocal behavior in birds
It is suggested that the capacity for closed‐mouth vocalization was present in at least some extinct nonavian dinosaurs and may have been limited to sexually selected vocal displays, and hence would have co‐occurred with open‐mouthed vocalizations.
A global analysis of song frequency in passerines provides no support for the acoustic adaptation hypothesis but suggests a role for sexual selection
The results suggest that the global variation in passerine song frequency is mostly driven by natural and sexual selection causing evolutionary shifts in body size rather than by habitat-related selection on sound propagation.
The Avian Lingual and Laryngeal Apparatus Within the Context of the Head and Jaw Apparatus, with Comparisons to the Mammalian Condition: Functional Morphology and Biomechanics of Evaporative Cooling, Feeding, Drinking, and Vocalization
This chapter will concentrate on the functional-morphological interdependences and interactions of the lingual and laryngeal apparatus with each other and with the skull and jaw apparatus.
A Semiotic Modern Synthesis: Conducting Quantitative Studies in Zoosemiotics and Interpreting Existing Ethological Studies through a Semiotic Framework
In this paper, I present an argument that quantitative behavioural analysis can be used in zoosemiotic studies to advance the field of biosemiotics. The premise is that signs and signals form


Morphology and mechanics of the larynx of the pigeon (Columba livia L.): A drill-chuck system (Aves)
The glottal apparatus operates as a drill-chuck system in which the arytaenoids are taken as the graspers (chuck jaws) and the model is studied by a movement- and electromyographic analysis of three commonglottal actions: respiration, reaction to water, and reaction to touch.
The Structure of Aerial Displays in Three Species of Calidridinae (Scolopacidae)
ABsT•-•CT.--Sandpipers in the subfamily Calidridinae (Scolopacidae) breed in the Arctic and Subarctic. In all species, unpaired males engage in distinctive aerial displays. Such displays are
Directional acoustic radiation in the strut display of male sage grouse Centrocercus urophasianus.
The results of this study suggest that males may reach females with a high-intensity signal despite their preference for an oblique display posture relative to those females.
Functional morphology of the sound‐generating labia in the syrinx of two songbird species
The size and microstructure of the labia are related to their acoustic function in two songbird species with different acoustic characteristics, the white‐crowned sparrow and zebra finch and a mechanism for their biomechanical function is suggested.
Nordic rattle: the hoarse vocalization and the inflatable laryngeal air sac of reindeer (Rangifer tarandus)
The vocal tract of reindeer has evolved an unpaired inflatable ventrorostral laryngeal air sac and individual acoustic recognition may have been the primary function in the evolution of a size‐variable air sac, and this function is retained in mother–young communication.
Pectoral Sandpiper Calidris melanotos : first record for Tanzania
The authors' nests were both >1 m high, similarly positioned to those of other Serinus species, and there seems no obvious reason for this nest height difference, though it may reflect a difference in potential predators or in conspecific competition for sites.
Melanin–based plumage coloration and flight displays in plovers and allies
The results are most consistent with the sexual–selection hypothesis, and suggest that melanized plumage has evolved to enhance the aerial displays of male plovers.
Ecology and Evolution of Social Organization in Arctic Sandpipers
There is a striking diversity of social systems in calidridine sandpipers, that is, in the styles of habitat exploitation they have evolved in the arctic and subarctic habitats to which their breeding is confined.
Breeding Vocalizations of Baird's Sandpiper Calidris bairdii and Related Species, with Remarks on Phylogeny and Adaptation
Vocalizations of Baird's Sandpiper were recorded in northeastern Alaska, U.S.A and are structurally homologous with call types described for other calidridine species.
Larynx and pharynx of crows (Corvus corone L. and C. Monedula L., passeriformes: Corvidae)
It is concluded that the "drill-chuck" mechanism operating in pigeons, and probably in most other avian orders, can not work in the crow's larynx, and supports the assumption that 2 types of avian larynges are found: a Passeriform and a non-Passeriform type.
