Bat Adventures and Bat Detectors

Since I have started writing about bats, I have mentioned often about my bat detector. I’ve had a few inquiries about what the heck it is. As as wedding gift in 2018 good friends of ours and fellow ghouls gave us a bat detector. We all became really interested in them after using one for the bat walk put on by High Park Nature Centre. Since receiving one as a gift my husband and I have been on many of our own bat walks.

I guess I should explain a bit more about bat detectors, what they are and what they can do.

bat detector is a device used to detect the presence of bats by converting their echolocation ultrasound signals, as they are emitted by the bats, to audible frequencies, usually about 120 Hz to 15 kHz. There are other types of detectors which record bat calls so that they can be analysed afterward, but these are more commonly referred to by their particular function.

Bats emit calls from about 12 kHz to 160 kHz, but the upper frequencies in this range are rapidly absorbed in air. Many bat detectors are limited to around 15 kHz to 125 kHz at best. Bat detectors are available commercially and also can be self-built. (source Wikipedia) To learn more check out the full article over on Wikipedia.

This article has a clip on what it sounds like when you hear a bat on your detector. After time, you can actually recognize bat types as well as tell when there is one or more flying by.

The model I have is the Bat Seeker 4. It looks like below. Sure I’d love a higher end detector, but this one works great!

If you are looking for something a bit more higher end, that has more bells and whistles and can possibly record the bat sounds, please check out The Bat Detectors Buying Guide. They are quite a bit more expensive than the Bat Seeker (which runs at about $45) and if you are just starting out, the more advanced versions may be confusing for you. I strongly suggest you start out with something more basic.

Do you plan on buying a bat detector and go on your own bat adventures?

Each time I post, I am going to also suggest music that goes with bat adventures! Today I’m suggesting The Gnarly Ones and the song Night Rider. They are a Toronto Surf band that I just discovered! I hope they are still performing once we are out of Covid Jail!

Here is a link I’ve created to all of our bat sightings.

Important: Do not handle bats. They can carry the rabies virus. Only those who have been properly vaccinated and have knowledge of bats should be handling them. If you find a bat in your home call a bat rescue. Do not call an exterminator, call a rescue. Bats are important for our environment. I have links below for rescues.
