Crow Research

Transforming observations through technology


Yes, crows! As part of a multi-year partnership, I’ve been working with volunteer researchers observing and studying the thousands of crows that roost in Lawrence, MA each winter. I provide insight and guidance when it comes to how we can use new and emerging technologies to enhance our ability to observe these birds in exciting new ways.

Both of the below reports are treated as living documents, which we edit and update as time goes on, and share publicly with others in the community.

Counting Research

Beginning in mid 2020 our observations shifted to focus more on being able quantify the bird population in the Lawrence roost. While previous numbers were based on visual estimates, we sought to develop data-driven methods that could not only quantify the population but also produce proof of our count that other researchers can audit. Below is a sample of the report I prepared on how photographic technologies and automatic counting systems can be used to determine the size of a crow roost with a high degree of accuracy.

Acoustic Activity Research

Much earlier in my work with the Lawrence roost, I developed a process for recording and analyzing the acoustic activity of the crow roost. The following is a description of the process and custom software I developed.
