Software - Vireo

Posted in

The software Vireo calculates heart rate from remote recordings using heart rate telemetry. It was co-developed by Isabelle-Anne Bisson, Research Associate at the Smithsonian Institution’s Migratory Bird Center, and electrical engineer, Paul Kelley of NOAA (National Oceanic and Atmospheric Association) and Severn Electronics. From up to 20-hour portions of continuous field recordings of heart rate using MP3 technology and capability, Vireo allows us to extract the bird’s heart rate using a series of filters to remove spurious data and autocorrelation algorithms that provide heart rate with one-second time stamps. This program has been tested on heart rate telemetry data for 13 black-capped Vireos monitored in 2008 where the recovery rate for heart rate data was approximately 60%—a 20% increase from previous manual data analysis methods.

Compatibility with Movebank: 

This program does not access data directly from Movebank. However, heart rate data files can be stored and shared in Movebank.
