Mobbing Calls of the Phainopepla

-When mobbing potential predators, male Phainopeplas (Phainopepla nitens) utter smoothly upswept vocalizations, unlike the harsh, staccato mobbing calls of other birds and mammals. A Phainopepla repeats this call as it approaches the bottom of its diving arc over the predator. We suggest that these calls do not serve to attract additional mobbers to the scene. Rather, they appear to emphasize the diving attacks directed toward the predator. Birds and mammals commonly call while harassing or…

We examined the acoustic structure of mobbing calls of 52 species of passerines representing an array of taxa. Marler suggested that calls given during mobbing have char- acteristics enhancing

Barking and mobbing

The Behavioural Dynamics of Great Tits (Parus major) Approaching a Predator

There is a deadly risk of mobbing at a predator (= approaching it, usually alarm calling at the same time), as evidenced by a long list of published and unpublished accounts of a fatal or nearly

Giant honeybees (Apis dorsata) mob wasps away from the nest by directed visual patterns

Evidence is given that shimmering honeybees utilize directional alignment to enforce their repelling power against preying wasps, which can be identified as predator driving which is generally associated with mobbing behaviour in vertebrate species.

Alarm Response in Some Wetland Associated Animals

There appears to be evolutionary connection between feeding behavioural and alarm response, and some wetland associated animals e.g. langurs and rhesus associated with Galta kund at Ambagarh Reserve Forest, near Jaipur, Rajasthan do not respond to alarm cues.

How to Study Predator Recognition

The meeting of a prey and a predator can be organized both in the wild and in captivity, and the representativeness of experiments is mainly a problem, since the conditions here never fully tally with those in theWild.

Evidence for Abilities of Predator Recognition

If we study the ability of birds to recognize predators, we must first make clear how accurate recognition we are interested in. It is the same as if we were to survey children’s ability to recognize



Localization of Passerine Seeet and Mobbing Calls by Goshawks and Pygmy Owls

The evolution of alarm calls is discussed in terms of efficient prey communication, following Darwin's “antithesis principle”, rather than predator selection for non-localizability.

Locatable and Nonlocatable Acoustic Signals for Barn Owls

Physical parameters of sound that affect acoustic location in the barn owl were studied and differences in locatability between the two classes of signals are not due to the reasons given by Marler for predators in general.

Similarity of a Tyrant-Flycatcher and a Silky-Flycatcher: Not All Character Convergence Is Competitive Mimicry

The Crested Black-tyrant (Knipolegus lophotes), a tyrantflycatcher of open scrub and dry areas in eastern South America, is equally convergent to the unrelated Phainopepla (Phainopespla nitens) ofopen scrub anddry areas of western North America, but the resemblance does not seem to have been noted before.

A Case of Convergence in Vocal Signals between Marmosets and Birds

The hypothesis that signal forms should converge under similar selection pressures exerted by the physical configuration of the habitat, the social structure, and the function of the signal, such as aggregation or dispersal and long or short distance communication, is supported.


In many winter flocks, including those formed by shorebirds, the birds are likely to be only distantly related, and 'alarmism' could only be maintained as a result of kin selection if the disadvantage of calling were extremely small.

Ecological Sources of Selection on Avian Sounds

This study describes selection derived from habitat acoustics on the physical structure of avian sounds. Sound propagation tests were made in forest, edge, and grassland habitats in Panama to

Brood Size and the Use of Time and Energy by the Phainopepla

A Phainopepla incubating or feeding 2 nestlings in the coastal woodlands has a mean harvesting rate virtually identical to that of a bird in a comparable stage of breeding in the desert, when calculated on an energy expended per young fledged basis.

The Behavior of Communicating: An Ethological Approach

W. John Smith revises the traditional ethological concept of displays, and in a final chapter develops the further concept of formalized interactions, which extends the discussion to formal patterns of behavior that, unlike displays, are beyond the capabilities of individual performers.
