How can computers learn to recognize birds from sounds? The Cornell Lab of Ornithology and the Chemnitz University of Technology are trying to find an answer to this question. Our research is mainly focused on the detection and classification of avian sounds using machine learning – we want to assist experts and citizen scientist in their work of monitoring and protecting our birds. BirdNET is a research platform that aims at recognizing birds by sound at scale. We support various hardware and operating systems such as Arduino microcontrollers, the Raspberry Pi, smartphones, web browsers, workstation PCs, and even cloud services. BirdNET is a citizen science platform as well as an analysis software for extremely large collections of audio. BirdNET aims to provide innovative tools for conservationists, biologists, and birders alike.

This page features some of our public demonstrations, including a live stream demo, a demo for the analysis of audio recordings, an Android and iOS app, and its visualization of submissions. All demos are based on an artificial neural network we call BirdNET. We are constantly improving the features and performance of our demos – please make sure to check back with us regularly.

We are currently featuring 984 of the most common species of North America and Europe. We will add more species and more regions in the near future. Click here for the list of supported species.

Have you ever heard a bird sound you couldn’t ID? Learn how to use our BirdNET smartphone app to identify your mystery birds on a trip through Sapsucker Woods!

Learn how to identify birds by sound with the Cornell Lab of Ornithology’s free BirdNET mobile app and website. Advances in machine learning are making it easier to identify birds by their sounds. Q&A with BirdNET developer Stefan Kahl.

The live stream demo processes a live audio stream from a microphone outside the Cornell Lab of Ornithology, located in the Sapsucker Woods sanctuary in Ithaca, New York. This demo features an artificial neural network trained on the 180 most common species of the Sapsucker Woods area. Our system splits the audio stream into segments, converts those segments into spectrograms (visual representations of the audio signal) and passes the spectrograms through a convolutional neural network, all in near-real-time. The web page accumulates the species probabilities of the last five seconds into one prediction. If the probability for one species reaches 15% or higher, you can see a marker indicating an estimated position of the corresponding sound in the scrolling spectrogram of the live stream. This demo is intended for large screens.

Reliable identification of bird species in recorded audio files would be a transformative tool for researchers, conservation biologists, and birders. This demo provides a web interface for the upload and analysis of audio recordings. Based on an artificial neural network featuring almost 1,000 of the most common species of North America and Europe, this demo shows the most probable species for every second of the recording. Please note: We need to transfer the audio recordings to our servers in order to process the files. This demo is intended for large screens.

Ultrasonic animal repellers have been a craze among homeowners. It’s perceived as an eco-friendly and mess-free solution to drive the pesky birds away. You just install it, turn it on, and let it do its job. With the right installation and placing, these repellers should discourage birds from landing on your lawn or property. But what is ultrasonic bird repeller and does it work?

In this post, we will discuss these points together with ultrasonic repeller suggestions.

How ultrasonic repeller works

Ultrasonic repellers use high-pitch sounds that will irritate animals, including birds. Unlike sonic or mp3 bird scares, these devices produce ultrasonic soundthat humans can’t hear. This means that you can drive away birds without being a nuisance to your neighbors.

It can also affect rodents, squirrels, raccoons, and other pests. Take note, however, that if you have birds as pets and other smaller animals that can be affected by the sound, ultrasonic repellers may not be the right choice.

Most of these repellers are solar-powered while others are equipped with long-lasting batteries that need to be recharged once in a while. It’s best to choose one that doesn’t require frequent maintenance to ensure that your property is guarded against pest birds all day long.

So does it drive away birds? Yes, it could. However, the answer to this will also depend on the deterrent technology of individual devices. Make sure that the one you’re going to purchase has been tried and tested to work outdoors. If you want to skip the hassle of scouting for the right model, we’ve picked five of the best options in the market.

Benefits of using ultrasonic repellent

There are many benefits to using ultrasonic repellents as long as you don’t have pets that can be harmed by the sound. Here are some of the advantages of installing an ultrasonic repellent in your property.

✔️Eco-friendly

Instead of using deterrent gels and other chemicals to discourage the birds from nesting on your property, you can use ultrasonic devices instead. These are eco-friendly and won’t ruin your yard as chemical solutions do.

✔️More humane than other solutions

Many homeowners use gel or paste deterrents, which, in turn, stick to the bird’s feathers. This can affect their flight and possibly lead to death. And since some birds are protected by the law, it’s best to use a humane solution for the bird problem.

The birds will be annoyed by the sound, but it will not harm them in any way.

✔️Long-lasting

Unlike owl statues and shiny tapes, ultrasonic repellers last long if maintained well. For solar-powered units, you barely have to do anything once it’s installed. Just ensure that the repeller is waterproof and made for outdoor use.

What to look for when buying one

If you’re planning to buy an ultrasonic bird repeller, it’s best to look for the following features.

✔️Construction

Again, the ultrasonic repeller should be suitable for outdoor use. It means that the unit can endure rain, sunlight, and other outdoor elements.

✔️Deterrent technology

What kind of deterring power does the repeller have? Look for one that emits high-frequency sound with flashing lights. This won’t just irritate the birds but also scare them away with the blinding beams.

Most outdoor ultrasonic repellers are motion-activated. Once a movement registers on its sensor, it will emit sound and engage the blinking light. It’s best to place this on the spot with the least foot traffic so the sensor won’t react on passers-by and other typical movements on your property.

✔️Covered pests

Check which pests the ultrasonic repellent blocks. Usually, it will drive away squirrels, deer, rodents, insects, birds, and raccoons. It’s like hitting many birds with one stone if your place is mired with destructive stray animals.

✔️Power

When it comes to power, look for a solar-powered one. It recharges and works during the day then works on battery mode at night. This way, you no longer have to plug it in an electrical outlet or change batteries after a few weeks.

✔️Warranty

Of course, you wouldn’t want to place your money on such a risk. Make sure that the seller allows a few days of warranty so you can see if the device works.

✔️Price

It’s never a good idea to spend a whole fortune on an expensive ultrasonic deterrent. It’s best to purchase an economical model and pair it with other inexpensive bird deterrents. That way, you drive the birds off your property without breaking the bank.

Tips for a more successful bird proofing

After purchasing the right ultrasonic repellent, you must use it properly. Here are some tips to increase the deterrent effect of the device.

✔️Use more deterrent methods

Aside from using an ultrasonic deterrent, you should also employ other methods like shiny discs, decoy predators, scare tape, chimney cowls, and more. This will complement with the ultrasonic device. Also, it provides variations to your scares. It will prevent birds, especially pigeons, from outgrowing the deterring effect.

✔️Install it before the bird season

Take note that you should install the ultrasonic device and other scares before the bird season. It’s much easier to keep the birds away if they haven’t grown accustomed to your property.

✔️Keep your property clean

As much as ultrasonic repellers work, some birds are bold enough to endure or evade its effects. Remove any bird attractants and possible food sources that may encourage the birds to land on your property.

✔️Check the device regularly

Ultrasonic repeller devices aren’t a set-it-then-forget-it solution against birds. Once in a while, you should check if the parts are intact and if it’s still working correctly. Solar-powered units may still need battery replacements once the old one corrodes over time.

✔️Install more than one device

If you have a large lawn, it’s best to install more than one ultrasonic device to cover more ground. Spread it in different corners and spots in your yard where birds tend to flock.
