Vocal convergence and social proximity shape the calls of the most basal Passeriformes, New Zealand Wrens

Autor: Ines G. Moran, Yen Yi Loo, Stilianos Louca, Nick B. A. Young, Annabel Whibley, Sarah J. Withers, Priscila M. Salloum, Michelle L. Hall, Margaret C. Stanley, Kristal E. Cain

Publikováno v: Communications Biology, Vol 7, Iss 1, Pp 1-15 (2024)

Abstract Despite extensive research on avian vocal learning, we still lack a general understanding of how and when this ability evolved in birds. As the closest living relatives of the earliest Passeriformes, the New Zealand wrens (Acanthisitti) hold

Genetic divergence between isolated populations of the North Island New Zealand Rifleman (Acanthisitta chloris granti) implicates ancient biogeographic impacts rather than recent habitat fragmentation

Autor: Sarah J. Withers, Stuart Parsons, Mark E. Hauber, Alistair Kendrick, Shane D. Lavery

Publikováno v: Ecology and Evolution, Vol 11, Iss 11, Pp 5998-6014 (2021)

Abstract This research investigates the extent and causal mechanisms of genetic population divergence in a poorly flighted passerine, the North Island Rifleman or Titipounamu (Acanthisitta chloris granti). While this species has a historically widesp

Improved methods for reducing translocation mortality and obtaining reliable population projections for reintroduction of the New Zealand Rifleman Acanthisitta chloris

Autor: Mark E. Hauber, Sarah J. Withers, Doug P. Armstrong, Stuart Parsons, Tamsin Ward-Smith

Publikováno v: Bird Conservation International. 29:542-557

SummaryDespite many notable successes, the failure rate of animal translocations remains high. Conservation practitioners and reintroduction specialists have emphasised the need for ongoing documentation of translocation attempts, whether successful

Geographic patterns of song variation reveal timing of song acquisition in a wild avian population

Autor: Dianne H. Brunton, Louis Ranjard, Sarah J. Withers, Howard A. Ross, Stuart Parsons

Publikováno v: Behavioral Ecology. 28:1085-1092

Geographic patterns of song variation are common in passerines and can develop as a consequence of the mechanisms of song acquisition and dispersal. In particular, the timing of dispersal relative to the sensory learning phase and the time of song cr

Integration over song classification replicates: Song variant analysis in the hihi

Autor: Howard A. Ross, Sarah J. Withers, Louis Ranjard, Dianne H. Brunton, Stuart Parsons

Publikováno v: The Journal of the Acoustical Society of America. 137:2542-2551

Human expert analyses are commonly used in bioacoustic studies and can potentially limit the reproducibility of these results. In this paper, a machine learning method is presented to statistically classify avian vocalizations. Automated approaches w
