SummaryAuditory tuning curves of a small songbird, the great tit (Parus major), and of its principal avian predator, the European sparrowhawk (Accipiter nisus), were determined by an operant positive reinforcement conditioning procedure, using the method of constant stimuli. Thresholds were measured by the criterion of a 50% correct response and a d′ of 1.5 for intra- and interspecific comparison, respectively. The best frequency of both species was 2 kHz, the hawk being 6.5 dB SPL more… 
Comparison of Vocal Signals of Three Species of African Finches
African finches of a monophyletic group in the Passeridae nest in colonies with roofed nests thatched of dry grass-stems, with some idea of the selection pressures in the evolution of these signals.
The great tit's (Parus major) auditory resolution in azimuth
The duration of the stimulus had no effect on the resolution in azimuth for a range of durations from 40 ms to 300 ms, which suggests that the great tit may locate a sound source in an open loop fashion.
Convergent characteristics of begging vocalisations in Australian birds
The findings of this study suggest that the potential risks associated with begging in Australian birds are offset by the benefits gained from producing loud, wide band vocalisations that can be easily detected and located by parents.
Acoustic location of conspecifics in a nocturnal bird: the corncrake Crex crex

The results gave no evidence of corncrakes moving specifically in order to locate the source of the sound; they suggest that males moved toward or away from the already located sound.
Zebra finch song is a very short-range signal in the wild: evidence from an integrated approach
It is shown that wild zebra finch song is a very short-range signal with an audible range of about nine meters and that even the louder distance calls do not carry much farther, compared with songbirds that use their song as a long-range advertisement signal.
Auditory performance in bald eagles and red-tailed hawks: a comparative study of hearing in diurnal raptors
Auditory function was assessed in bald eagles, as well as in red-tailed hawks, to provide a framework within which acoustic alerting signals might be developed.
Effects of Cover on Loud Trill-Call and Soft Seet-Call Use in the Crested tit Parus Cristatus
It is suggested that the long-range part of contact communication in crested tits is strongly affected by the level of perceived predation risk, in accordance with the data on hearing ability of predators.
The adaptive utility of Richardson’s ground squirrel (Spermophilus richardsonii) short-range ultrasonic alarm signals
It is concluded that the size of the active space influences signalling strategy and that squirrels emitting ultrasonic calls can signal conspecifics to the exclusion of distant predators.
studied production specificity and contextual independence in the alarm calls of seven marmot species (
This essay aims to make two simple points about the evolution of functionally referential alarm communication, and suggests that species must have the perceptual and motor abilities to respond differently to acoustically-distinct alarm vocalizations.


An anti-predator response in the great tit (Parus major): Is it tuned to predator risk?
Two semi-quantitative predictions about the intensity of defence against a predator based on the associated costs and benefits as a function of predator species, were examined in great tits (Parus major) feeding nestlings, with the exception of the response to the pigmy owl.
Effects of Nesting Sparrowhawks on Nesting Tits

The hawk nests are shown to be occupied by Sparrowhawks and thus to analyze the predator's effect on the prey population, which results in a population of undisturbed birds near it.
The active space of red-winged blackbird song
SummaryActive space, that distance from the source over which signal amplitude remains above the detection threshold of potential receivers, was determined for Red-winged Blackbird (Agelaius
Sound transmission and its significance for animal vocalization
Two facts mitigating against Morton's sound “window” as an explanation for lower frequencies in songs of forest as opposed to open country birds are presence of similar “windows” in both habitats and restriction of windows to a zone close to the ground in most habitats.
A Comparative Study of the Songs and Alarm Calls of some Parus Species
Titmice vocalizations are presented with a view to examining variation within and between species, andSpectrographic and oscillographic analyses are made of territorial song and alarm calls.
Comparative Studies of Hearing in Vertebrates
This chapter discusses the evolution of hearing in the Mammals and the structure and function of the Avian Auditory System, as well as the nonlinear properties of the Peripheral Auditory system of Anurans.
Behavior and psychophysics of hearing in birds
It is generally agreed that birds and mammals share a common ancestry in the class Reptilia dating back about 250 million years, and it is not uncommon to find birds placed between reptiles and mammals, particularly on the basis of anatomical criteria.
Auditory sensitivity, equal loudness, temporal resolving power, and vocalizations in the house finch (Carpodacus mexicanus).
Absolute thresholds for pure tones were measured in four house finches by use of avoidance conditioning and a modified method of limits and the average power spectra of selected individual vocalizations are presented.

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the
