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.

This app lets you record a file using the internal microphone of your Android or iOS device and an artificial neural network will tell you the most probable bird species present in your recording. We use the native sound recording feature of smartphones and tablets as well as the GPS-service to make predictions based on location and date. Give it a try! Please note: We need to transfer the audio recordings to our servers in order to process the files. Recording quality may vary depending on your device. External microphones will probably increase the recording quality.

Dedicated to advancing the understanding and protection of the natural world, the Cornell Lab joins with people from all walks of life to make new scientific discoveries, share insights, and galvanize conservation action. Our Johnson Center for Birds and Biodiversity in Ithaca, New York, is a global center for the study and protection of birds and biodiversity, and the hub for millions of citizen-science observations pouring in from around the world.

Based at the Cornell Lab of Ornithology, the K. Lisa Yang Center for Conservation Bioacoustics collects and interprets sounds in nature by developing and applying innovative conservation technologies across multiple ecological scales to inspire and inform conservation of wildlife and habitats. Our highly interdisciplinary team works with collaborators on terrestrial, aquatic, and marine bioacoustic research projects tackling conservation issues worldwide.

I am a research analyst within the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology and the community manager of the BirdNET app. I am actively involved in environmental conservation through scientific inquiries and public engagement. Understanding the relationship between natural sounds and the effects of anthropogenic factors on the communication space of animals is my passion.


While pausing to look at the plants, we were able to hear several birds overhead. Rock Cut is known for its birds, and watchers often come here. We were distracted from hiking for a few more minutes when we accidentally became bird watchers ourselves. They were quite noisy, so we knew they were around. One of them had a call like a squeaking door, and it would have been nice to know what kind of bird it was. But even with stopping and actually looking, we were only able to spot one small, brown bird that had a different call.

These are the ways Hitchcock saturates the viewer with the presence of the birds. Occasionally through visuals, but very often simply through sound and timing. He makes sure we hear them early and often, especially when there is conflict on screen, and immediately before the first mass attack, when the film takes its most decisive turn, he substitutes another source for a now-familiar sound before he yanks out the rug.

This pioneering sound-identification technology is integrated into the existing Merlin Bird ID app, meaning Merlin now offers four ways to identify a bird: by a sound, by a photo, by answering five questions about a bird you saw, or by exploring a list of the birds expected where you are.

To train Merlin to identify bird sounds, the team assembled around 500 recordings for each species. Working on computers, volunteers trimmed and classified each recording by hand before it was fed into a machine-learning model that learned each song and its variations. The app also uses eBird observations to know which birds are most likely to be found at a particular place and time.

Merlin project leader Jessie Barry says that Merlin sound ID marks a great leap forward in the ability for people to connect with and understand the sounds of the natural world around them. Macaulay Library web designer Matt Schloss, who describes himself as an advanced beginner and beta-tested the app, agrees.

Use our quick, clickable guide for identifying backyard birds by the sounds they make! Choose any of these popular different bird species to hear its typical bird sounds and bird calls, from vocalizations of parrots to the chirping of songbirds. As you're gardening in your backyard, relaxing outdoors or wandering in the woods, you might be able to use our guide to identify a few distinctive bird calls or bird noises. Identification of song bird sounds has a rich history; in the past, it was fairly complicated and frequently required mnemonics. For instance, the blue jay is recognized for singing this bird sound, "queedle, queedle, queedle," and the mourning dove bird sound can be written as "hooo-ah hoo-hoo-hoo." The northern flicker sounds like "squeechu-squeechu-squeechu," which might be easy to confuse with "queedle" unless you've heard these wild bird sounds yourself! It's also helpful to consider where you are when you're trying to identify birds chirping sound; check out the maps to see different bird species or if a particular bird is actually found in your area.

Today, identification is easier when you can listen to sounds of birds singing in short sound clips. Click a bird type to hear birds tweeting their "language." Note that some of these birds have different birds sounds based on the situation, too. For instance, many songbirds have "alarm" bird noises along with its normal tittering that can sound a little different. Tweets can also have a different tune than full bird calls. But this list of 50 sounds of birds should certainly be able to get you started!

There are plenty more migratory bird sounds to discover, too. If you really want to become a pro at bird calls identification, you'll want to learn more about the pitch, rhythm, and repetition of birdsong so you can identify birds by sound!

When on earth, iNaturalist user or not, we will come across something UGLY at least once. So, regardless whether you have observed it or not, what do you think is the ugliest bird or bird sound?

For me, I think the sound of Bald Eagles (Haliaeetus leucocephalus) is just the worst. I have worked at a rehabilitation center with them and just Ugh, they make a really loud, throaty, wet call that is nowhere near what you would expect from such a magnificent creature. See you out there!

Andrew Whitehouse is an anthropologist and birder teaching at the University of Aberdeen, Scotland. His work has explored conservation conflicts in western Scotland, landscape and anthropology and, more recently, people's relations with birds through sound. He is co-editor of the volume Landscapes Beyond Land: Routes, Aesthetics, Narratives published by Berghahn in 2012.

Life in such a perfect world was thus accompanied by the presence of birds, a presence made most readily and delightfully manifest in their songs. When once familiar companions no longer accompanied local residents, the shock was unexpected and unnerving.

The environmentalism spawned by Silent Spring has constantly drawn attention to the ways that ecosystems, both local and global, are affected by human activity. What prospers and what disappears are causally bound together with human actions in ways that are sometimes readily apparent and sometimes barely perceptible. I explore the associations that people perceive as emerging between bird sounds and environmental changes. Following the semiotic approach of Kohn,10 I argue that the symbolic and moral connotations of listening to birds in the Anthropocene follow from their iconic and indexical grounding in places, producing an anxious semiotics in which even positive associations can have portentous or uncertain implications. My argument progresses from recent claims made by Bernie Krause about the evolution of soundscapes and their disruption by humans to a series of narratives contributed to the Listening to Birds project: an anthropological study of people's relations to birds through sound. Finally, I invite the reader to listen to four recordings and consider the sounds they hear as a means of sensing life in the Anthropocene.

So here we have a sense of the sounds of the world developing in relation through the geological eras and into the present day. The different types of sound that Krause outlines might themselves be regarded as sonic epochs in which a particular category of sound emerged or tended to predominate. As such, Krause is implying that we have now entered the epoch of anthrophony and that human sounds are drowning out the biophony and geophony in many parts of the world. The Anthropocene has also ushered in a new kind of anthrophony, with the sounds of industry, machinery, combustion engines and electronic amplification being a rather different and more disruptive type of human-induced sounds than those that would have predominated in the pre-industrial era. As such, I would argue that one can differentiate between pre- and post-Anthropocene anthrophony, the former tending to integrate more closely with other sounds and the latter often disrupting or dominating them. Indeed, Krause's main concern is not with the effects of anthrophony in general but the effects of what he calls electromechanical sounds. Problematic sounds don't so much originate in human bodies themselves but in Anthropocene technologies used by humans. 2351a5e196
