How Citizen Scientists are Helping the Cause of Bat Conservation

About fifteen of us were gathered in a classroom one Thursday evening last month on San Francisco’s South Bay. We were there to hear a talk as part of a bat banding workshop and field demonstration  at a riparian restoration site. The wildlife ecologist and bat expert who gave the talk explained why the nocturnal creatures deserve our protection and respect.

In the field the following night, we watched our teacher wade chest deep across a creek, deftly extract a tiny bat from a mist net by the light of his headlamp, and measure, observe, and band it back at our camp.

As I watched, I imagined what it would be like to be a scientist who gets to study and protect these fascinating animals every day, and I wondered if there was a way for a non-scientist like me to get involved. Read the rest of this entry »

Become a Bat Detective

We couldn’t have asked for a better citizen science project to start off October, a month often associated with Halloween and all things spooky.

Introducing Bat Detective, a project that enlists citizen scientists to screen sound recordings of bats to classify their distinct calls. Bats are nocturnal, making them very difficult to spot with the naked eye, so a growing number of bat surveys are being done acoustically instead. Bat calls “leak” information into the environment each night through echolocation, which bats use to sonically navigate, socialize, and locate prey in the dark.

Citizen scientists from all over the world have already recorded about 3,000 hours of acoustic surveys. Bat Detective has split the surveys in 4-second snapshots, so there are actually millions of files to be sorted. With only a few scientists, it would be an incredibly tedious, perhaps even impossible task. However, with the help of citizen scientists like you, the job will get done much more quickly!

These classifications will be used to create a new algorithm to help researchers easily extract information from their sound recordings and more closely monitor threatened bat populations. Bats are an integral part of their local ecosystems, but one in every five species of bat will face extinction over the next 50 years.

Bats carry out lots of ‘ecosystem services’ like pollination and seed dispersal,” said Kate Jones, Professor of Ecology and Biodiversity at University College London and Zoological Society of London. “They also eat masses of insects. Losing bats means that all those services are degraded,” added Jones, whose Bat Detective project was made possible through Zooniverse , a popular online citizen science platform.

“The idea of Bat Detective really caught the imagination of the Zooniverse team, and when we heard the bat calls we were sold,” said Chris Lintott, director of Zooniverse. “The rapid sequence of calls that make up a feeding call, and which means the bat has found its prey, is once heard and never forgotten.”

Bats are also incredibly vulnerable to climate change, since their hibernation and migration patterns depend largely on weather patterns, so the success or failure of their local populations often serve as a early warning sign of the failing health of the local ecosystem as a whole. Need we say more?

Be sure to sign up for this sonically exciting and scintillating citizen science scheme! While you’re at it, check out our other bat-related citizen science projects in our Project Finder. You can help the Wisconsin Department of Natural Resources with acoustic bat monitoring or identify Indian flying fox bats with the South Asian Bat Monitoring Program.

Coming soon: a collection of Halloween-themed citizen science projects. Keep your eyes (and ears) peeled!

Citizen scientists make a difference in the San Juans

Up north, in Washington State’s tranquil San Juan Islands, members of the Kwiáht marine research team are hard at work keeping an eye on local sea life and terrestrial critters. Kwiaht, a word in the Coast Salish dialect, refers to a place that is physically healthy and spiritually clean.

The group hopes to ensure the continued health of the San Juan Island ecosystem by allowing local citizen scientists to participate in ecological research.

Want to volunteer? Contact Kwiaht’s program director to find out how you can become involved as well!

In addition to research and outreach, Kwiaht also aims to help restore terrestrial and aquatic ecosystems by working with public land managers to develop conservation strategies.
