Mini-symposia themes

Studying birds using passive acoustic monitoring

24 March 2023
Organizer: Vijay Ramesh

Passive acoustic monitoring (PAM) has emerged as a transformative tool for biodiversity monitoring. With advances in data collection, storage, and analyses, low-cost audio recorders are now being used to sample multiple locations simultaneously for long periods. As a passive and remote monitoring tool, an acoustic recorder captures a wide range of frequencies that contain information about the biotic and abiotic conditions at a given location. Today, acoustics have been used for a range of studies that include characterizing the long-term impacts of human activity on biodiversity, the seasonal movements of migratory taxa, and the effects of vegetation structure on vocalizing biodiversity, for instance.

In this mini-symposium, our speakers will provide examples of how bioacoustics is used for avian monitoring across the Indian subcontinent. A range of applications will be discussed, including the use of PAMs to monitor the impacts of ecological restoration on bird species, monitor the seasonal activity of an endemic rainforest bird, monitor birds across arid landscapes, use deep learning to detect endangered bird species, and monitor the behavior of bird hunting parties, for example.

Historical resurveys for bird monitoring

25 March 2023
Organizer: Ramnarayan K

Historically, ornithologists across the world have conducted exploratory expeditions to survey and document birds from different biogeographic regions. Such historical surveys create unique and valuable opportunities to study the change in bird populations and distributions over the years. India presents a handful of examples of such historical expeditions, some of which have been repeated more recently. This mini-symposium aims to bring together people involved in such surveys historically, or in the current times to discuss and deliberate on the insights from these resurveys and/or identify more opportunities for repeat surveys and expeditions.

We will also attempt to learn from other examples of resurveys from the Neotropics. At the Keynote talk by Dr Camila Gomez on the Columbia Resurvey Project, she will share the findings from their work and speak about the insights that such resurveys can provide.

Talk Title: Passive acoustic monitoring of avian communities and habitats


Sound is an important tool for surveying and monitoring bird populations. For many years, point count surveys and other types of acoustic censuses have provided detailed information about bird populations. More recently, advances in acoustic recording and data storage technology have made it possible to complement human surveys with passive acoustic monitoring (the use of unattended recording devices to capture long recordings from an environment).

In this talk, I will present recent research conducted with passive acoustic monitoring, highlighting the range of questions and scales that are enabled by the approach. I will use these examples to discuss the contexts where passive acoustic monitoring provides valuable extensions to human surveys, as well as limitations of the technology. In addition to presenting scientific findings, I will provide a practical introduction to passive acoustic monitoring including equipment selection and deployment, data management and curation, and analysis approaches. In doing so, I will highlight resources that are available for new practitioners, as well as emerging tools, such as machine learning based analysis of recordings.

Speaker Bio

Laurel Symes is the Assistant Director of the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology. In this role, her goal is to maximize the accessibility and effectiveness of acoustic tools for research and conservation. Scientifically, she coordinates the tropical biology research program, focusing in Central and South America and working with teams from Southeast Asia and Central Africa to develop research approaches and tools that span tropical terrestrial habitats. In addition, she works with the Yang Center capacity building team to develop introductory and advanced training materials and courses, and to provide intensive professional mentorship and training.
In her research, she works at the intersection of ecology, evolution, conservation, and technical development. She conducts research across a variety of taxa, including insects, frogs, bats, and birds in both temperate and tropical systems. She has a particular research interest in the evolution of signaling rates, how often animals repeat signals over days, months, or years, a historically difficult data type to access, and one that is central to understanding the signaling ecology of animals and to using acoustics to estimate population density.

Talk title: Colombia Resurvey Project – Assessing changes in bird communities over a century of landscape transformation


110 years ago, naturalists from the American Museum of Natural History led a series of expeditions to document bird diversity and abundance across a broad region of Colombia. Information from those expeditions exists mostly in the form of collection specimens, and as a compilation in a book written by Frank Chapman in 1917. Between 2019 and 2021 we resurveyed 6 regions that had been visited by Chapman and carried out standardized observations, as well as specimen collection, to document how bird communities have changed in this period. Our results are striking in terms of species composition and turnover. Ecosystem functionality, based on bird diversity, has changed radically even in regions where habitat transformation has not been that great. This project has opened a window to the past and will hopefully serve as a tool to continue monitoring variations in bird composition and ecosystem health towards the future.
