Peer-Reviewed Research and Natural-History Notes

Wewhare, N. and Krishnan, A. (2024)

Individual-specific associations between warble song notes and body movements in budgerigar courtship displays.
Biology Open, 13(10): bio060497.
DOI | Project summary | First Person interview

Analysis of 100 courtship bouts tests associations between warble-note types and synchronized body movements, identifying population-level and individual-specific coordination patterns.

Madabhushi, A. J., Wewhare, N., Binwal, P., Agarwal, V., and Krishnan, A. (2023)

Higher-order dialectic variation and syntactic convergence in the complex warble song of budgerigars.
Journal of Experimental Biology, 226(20): jeb245678.
DOI | Project summary

Longitudinal comparison of two budgerigar colonies identifies colony-associated differences in higher-order warble-song structure and convergence following social contact.

Wewhare, N. and Pandey, U. (2021)

Sequence-level vocal convergence in common marmosets.
bioRxiv.
Preprint | Project summary

The preprint tests audience-dependent changes in sequence structure and individual phee-call acoustics following pair formation. The manuscript is currently in revision.

Sarkar, R., Pal, T. S., Maji, S., Nandi, S., Lahiri, A., Basumatary, A. K., GP, A., Wewhare, N., Jahan, N., Jakhete, S., Bandyopadhyay, S., Adhikary, R., Paul, T., Majumdar, S., and Bhadra, A. (2025)

Sight, smell and more: What cues do free-ranging dogs use for decision-making while scavenging?
arXiv, 2512.00058.
Preprint | Project summary

Field choice experiments evaluate how free-ranging dogs integrate visual and olfactory information across alternative food-choice conditions.

Dhati, A. M., Wewhare, N., Devasthale, N. S., Sundar, S., Parulekar, N., and Krishnan, A. (2025)

Vocal sequences of diverse parrots suggest an important role for note repetition.
bioRxiv.
Preprint | Project summary

Across six parrot species, observed sequence metrics are compared with random, Markov, hidden-Markov, and renewal models; results identify prominent note repetition and support contributions from both renewal- and Markov-like processes.

Interviews and Profiles

Wewhare, N. (2024)

First person – Nakul Wewhare.
Biology Open, 13(10): bio061701.
Interview

Interview concerning research training in animal communication and the development of the budgerigar multimodal-courtship study.

Manuscripts and Analyses in Progress

These entries are unpublished and should not be cited as completed publications. They document current analytical scope and are explicitly separated from peer-reviewed and preprint outputs.

Wewhare, N. and Krishnan, A. (in preparation)

Vocal learning mediates aggressive interactions in budgerigars.
Unpublished manuscript in final preparation.
Project and current results

An observational analysis of associations among male aggression, mutual display, dominance, warble syntax, and learned contact-call repertoires within one mixed-sex colony. Estimates and interpretations may change during manuscript preparation and review.

Wewhare, N. (analysis in progress)

Vocal matching and the initiation of vampire-bat exchanges.
Unpublished PhD research.
Research theme | Project and visualizations

Preliminary models from Princeton pair recordings and Panama trio recordings test whether acoustic distance from a potential responder’s recent calls predicts response probability within five seconds. Playback and behaviour-linked analyses are ongoing.
