Thereare always lots of things to learn when moving to a new area. Here in Jalisco we found that the rainy season is a few weeks away by the rain birds letting us know.
At first they start with a lone one or two on the occasional evening at dusk and within a few weeks they are singing away pretty much day and night.
I love them. If you drive the cuota from Guadalajara to Colima, there is a canyon where you can hear them singing in the afdternoon and evening. They are so loud you can often hear them even if the windows are closed.
Is there anyway I can turn off the birds in the background of the rain and stream noises? I love the sounds alone but the birds keep me awake and really distract me when i'm trying to sleep or do something. It's really annoying.
Researchers at Oregon State University have created a new computer technology that can listen to multiple bird sounds at one time to identify which species are present and how they may be changing as a result of habitat loss or climate change.
"It's difficult to hear and identify even one or two bird species at a time, and when you have many of them singing at once it's even more difficult," said Forrest Briggs, a doctoral student in computer science at OSU.
"Birds are important in themselves, but also an early warning system of larger changes taking place in the environment," Briggs said. "Now we can tell down to the second when a bird arrives, leaves, when and where it's choosing to nest, that type of information. It's just not practical to do that with human monitoring."
"It would not be reasonable for a person to count birds once per minute, 24 hours a day, for three months, but we aim to obtain similar results with acoustic surveys," the researchers wrote in a recent study published in the Journal of the Acoustical Society of America.
The error rate of this technology is already similar to that achieved by human experts, Briggs said. In one day of testing, for instance, it produced 548 10-second recordings of sounds from 13 different bird species. It is also omni-directional, meaning the microphones do not have to be pointed right at the sound in question to function accurately, one of the limitations of some previous technology.
Researchers are still working out some issues, including interference caused by rain, not to mention people heard partying in the woods, and what appeared to be the bite mark of a bear on the microphone.
Though I often extol the virtues and merits of winter in the Central Valley, especially when it comes to birding, the whole truth is that we experience "bad" weather also, just like anywhere else. But even when the winter weather rolls in, the birds are still out there! And sometimes, despite our best planning efforts, a birding day happens to coincide with crummy weather.
Birders far more intrepid than I regularly brave the ice and snow of northern winters to see their favorite birds, so perhaps you should look to them for real tips on winter birding! For those of us in the valleys of California, the worst weather we see - wind and rain - is really comparatively mild.
1. The first is that birds are simply not as active during very windy weather, particularly small songbirds. It requires extra energy to fly in the wind, so most smaller birds conserve energy by hunkering down in a sheltered spot. Insects, which many small birds feed on, also don't fly much when it's windy.
2. When scanning the habitat for birds, a birder's brain is trained to pick up on movement. But when wind is moving everything in the environment, from leaves and branches to dust and clouds, honing in on the movement of birds is really challenging.
5. Birds look different in windy conditions. Odd as this may sound, it's true. The shape of birds, perched and in flight, can change drastically in the wind. An otherwise sleek bird may looked round and fluffed when perched in a cold wind, and a crestless bird can look deceptively crested when its feathers are ruffled from behind by the wind. Even more confusing are birds in flight. Riding a strong tailwind on bent wings, a buteo or raven can flash by, giving a confusingly falcon-like impression. And birds that typically don't kite or hover, like Bald Eagles, may face into a head wind and hang in the air over one spot for long periods of time.
There are just some bird songs that stop me in my tracks. I marvel at the complexity, the melody, the tone. They're the ones that stand out from the rest of the dawn chorus by their sheer beauty. I'm always grateful to be in the right place at the right time when I hear them.
Here's a link to download the FREE Audubon Bird Guide App: , so you can have bird songs in your pocket.
I include links to the online version of the Audubon Bird Guide for each of the birds listed below -guide and give links for the songs.
Veery. When I'm asked to pick my favorite bird song, this is it. The Veery can make two tones at the same time, using both sides of its syrinx to create harmony with itself. The song has a spiraling, descending flute-like tone. You can see the two tones on a spectrogram and read more about it here.
Wood Thrush. Really, all of the thrushes are amazing singers. But I like the bouncy lilt of the song of the Wood Thrush, as well as the strange, almost-metallic sound at the end of the song. It's a really weird noise that sets it apart from all other birds' songs.
Hermit Thrush. This one's song is clear, simple and yet complex at the same time. The longer tone at the start of the song sets a calming vibe, and then it gets all jumbly. It's a good one.
Bobolink. Yes, the R2-D2 bird. Its song is a very bubbly, metallic-sounding tumble of random notes. You'll find these birds nesting in Vermont's hayfields. Learn more about Audubon Vermont's work to help conserve the Bobolink:
Winter Wren. This bird wins the prize for the longest song. It's one of the fastest as well. Someone once told me it sounds like an electric guitar solo. Winter wrens like to nest and forage in messy tangles of fallen trees' root balls on the forest floor.
Red-eyed Vireo. This bird sings all day long. It doesn't matter how hot it is, or if it's raining. This bird is singing. The song is short, sweet and sing-song-ey. "Look at me. Way up high. Over here. In a tree." So very reassuring to hear this bird song at my side in the woods.
Blue-headed Vireo. Slow down the song of the Red-eyed Vireo and you've got the Blue-headed Vireo. Its song has long, long pauses between the phrases that invite you to listen for more.
When I find myself in a different part of the world, I listen to bird song in a whole different way. The part of my brain that tries to identify bird song doesn't engage, and I can more easily appreciate the tones and melodies of the songs. Enjoy this video shared with me by a good friend:
It's a long time since I've been on a sampling session in the wild, recording fresh sounds for myNoise. Blame it on the special situation we are currently facing with the Covid pandemic. Although I took advantage of being confined in the studio to produce more musical soundscapes, I gradually started to miss working on the sounds of nature. I know these are a favorite of many of you, too.
So I listened to past recordings and found some gems that were never published. I particularly enjoyed these recordings, made during the first days of spring, early in the morning. The session started at 5AM, when the tawny owls would soon be going to bed, and with the other birds slowly waking up. It ended at around 9AM, with titmice singing vividly. Winter is over. The mornings are still cold, very cold. But they all know it won't be so for much longer. Deliverance is near, and the good days will soon return!
These birds are often heard in grasslands of mostly native grasses and forbs, and many males together sound like a cacophony of high-frequency whistles and chips. Most of these highly migratory birds winter in the llanos (or plains) of Venezuela but return to grassy areas in Texas and much of the Great Plains to settle down and raise a family. As our larger grasslands get converted to other uses and whittled down in size, so die the sounds of so many grass-loving species, from prairie-chickens to several kinds of sparrows. In order to keep the buzzy sounds of dickcissels ringing aloud, conserve and protect the native grasses found on your property.
This little wren might be the most versatile and complex songster of the bunch. He reminds me of the late Freddie Mercury, who sang an array of highs and lows for the band Queen. While this wren is fairly drab, his song is absolutely wonderful and the one I miss most when leaving the western half of the state, where this bird can be found in thick vegetation. Be sure to pronounce his name correctly, like the Buick car. Spend some time listening to one as he changes things up after a spell, maybe in order to hold the attention of others. I know it works for me!
After successfully experimenting with nature sounds (a sample video is at the end of this article), I decided to create dynamic weather that could be changed simply by adjusting a simple parameter from the game engine. Once again, I began with an analysis before proceeding to recreate the sounds using synthesizers. Procedural dynamic rain is an excellent example, especially because a simple Wwise parameter can change the sound from light rain to pouring rain.
As I can't just recreate the sound of rain by watching its spectrum or waveform, I decided to scour the internet to research this topic. I found a meaningful paper from Cornell called "Toward Animating Water with Complex Acoustic Bubbles". It contains great work, and worth the read.
These were the main conclusions I drew from this research paper:
Through this, I realized that the sound of rain is comprised of the sound of millions of bubbles merging each second to form a spectrum resembling a noise-like sound (pink noise, to be more precise).
Based on this idea, I created a prototype of dynamic rain in Ableton Live using Serum. I split the whole sound into a few layers:
1. Light high-frequency boiling
2. Mid-frequency boiling
3. Stereo noise
4. Individual raindrops
To make it more realistic, I cross-referenced my prototype with a sample of recorded rain.
