Bonobos modify communication signals according to recipient familiarity

Bonobos (Pan paniscus) are experimentally tested whether bonobos are able to take into account the familiarity, i.e. the shared interaction history, when communicating with a human partner, and it is found that subjects took the recipients’ attentional state and their own communicative effectiveness into account by adjusting signal production accordingly.

The ‘culture of two’: Communication accommodation in ravens’ (Corvus corax) nonvocal signaling

Evidence is provided that raven pairs matched their repertoires, with recipients reciprocating the signals of their communication partners in relation to time spent together, which strengthens the hypothesis that the motives to form and maintain affiliate relationships may have been crucial in boosting not only cognitive but also communicative abilities.

Intentional communication: solving methodological issues to assigning first‐order intentional signalling

A four‐step scheme with 20 statistical operational criteria to distinguish between non‐intentional and first‐order intentional signalling is presented, thereby validating comparison across communicative modalities and species and promoting the generation and testing of hypotheses about the evolution of intentional communication.

Effect of bandwidth modifications on the quality of speech imitated by Alexandrine and Indian Ringneck parrots

Investigations showed that 500–3000 Hz spectral band is adequate for retaining the important perceptual information in the phrases uttered by human speakers and imitated by parrots, and confirmed that the Indian Ringneck parrots are capable of following the formant structure and pitch contour of the phrase uttered by the human subjects.

Birds associate species-specific acoustic and visual cues: recognition of heterospecific rivals by male blackcaps

It is shown that male blackcaps can associate species- Specific songs with species-specific plumage and also that they retain the memory of this association for an 8-month period without contact with heterospecific rivals, the first time a long-term memory of associations between species- specific signals from two different sensory modalities has been shown to be important for distinguishing conspecifics from heterosPEcifics.

VOCAL REPERTOIRE OF WILD BREEDING ORANGE-WINGED PARROTS AMAZONA AMAZONICA IN AMAZONIA

The Orange-winged Parrot is a highly social species and the complexity of its social interactions is reflected in the diversity of its vocal repertoire, which contains nine vocalizations that are classified in three behavioural categories.

The use of referential gestures in ravens (Corvus corax) in the wild.

Evidence is reported that the use of declarative gestures is not restricted to the primate lineage and that these gestures may function as 'testing-signals' to evaluate the interest of a potential partner or to strengthen an already existing bond.

Vocalizations of the Blue-fronted Amazon (Amazona aestiva) in the Chancaní Reserve, Córdoba, Argentina

Vocalization rates increased in alarm contexts and during the non-breeding season, probably as a result of increasing interactions between individuals, and it is suggested that songs were derived from a process of repetition and increasing variability from gutural calls.

VOCALIZATIONS OF BLUE-CROWNED CONURES (ARATINGA ACUTICAUDATA) IN THE CHANCANÍ RESERVE, CÓRDOBA, ARGENTINA

The calls of Blue-crowned Conures (Aratinga acuticaudata) are described and their contexts of emis- sion are described, finding that energy concentration may be a useful parameter to identify the species due to its low variability.

Display in monogamous pairs: a review of empirical data and evolutionary explanations

This paper reviews display between the members of established pairs and suggests that an explanation requiring that partners are in conflict for conspicuous display to evolve may provide a new interpretation of the idea of pair bonding.

Abstract: Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of
