Acoustic analysis of the budgerigar vocal repertoire [PDF]
The Journal of the Acoustical Society of America, 1984 Previous ethological studies of the budgerigar (Melopsittacus undulatus) have provided a functional description of the vocal repertoire [B. F. Brockway, Anim. Behav. 23, 294–324 (1964)]. The present study describes the acoustic structure of each of these complex vocalizations with an emphasis on the contact call.

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries
Angewandte Chemie, EarlyView.This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Bridging a gap : Interfacing vocal technique and repertoire
After an intense period of concerts and projects that involved learning large quantities of new music I realized that I often got vocally tired when learning music. I have always been a quick learner but my method of learning has not always been beneficial for my vocal health.

A comparative study of the function of heterospecific vocal mimicry in European passerines
, 2007 Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.

An Overview of the Barbary Macaque, Macaca sylvanus, Vocal Repertoire
Folia Primatologica, 2002 This study provides an overview of the vocalizations of Barbary macaques, Macaca sylvanus. Spectrographic displays of calls are presented along with photographs of the accompanying facial gestures. We give a general description of the contexts in which the different calls are uttered, with special regard to the age and sex of the caller.

Vocal recruitment for joint travel in wild chimpanzees [PDF]
, 2013 Joint travel is a common social activity of many group-living animals, which requires some degree of coordination, sometimes through communication signals. Here, we studied the use of an acoustically distinct vocalisation in chimpanzees, the 'travel hoo',
