Do birds migrate during night?

Can birds fly over my NOC-MiG microphone?

While it is true that anything can fly over your noc-mig microphone, the majority of sounds will come from common and widespread birds, so it pays to be cautious. When presented with a tricky call, you can download sample recordings from Xeno-Canto.

What type of microphone should I use to record night flight calls?

Nocturnal flight calls of Song Thrush, Redwing and Blackbird, recorded using a shotgun microphone and an Olympus LS-12 portable audio recorder in Cambridge, England, at 23:50 on 29 October 2019 (Jon Heath). Personally, for detecting night flight calls, which often can be quite quiet, I prefer the parabolic mic for the extra volume it gives.

How are bird call signatures used to track migration?

The process involves the use of sound-recording equipment to capture the flight calls of migrating birds, then detecting and identifying the call signatures using computer software.

What type of microphone do you use for NOC-MiG recording?

Most noc-mig recordists use either a shotgun microphone (see here) or a parabolic microphone (see here ). Shotgun mics are designed to limit sound pickup from the sides to help isolate the sound of interest, but they do not increase the volume of a sound.

What are the best practices for recording bird migration?

A change in wind direction is also thought to be a good cue for onset of migration. Position your recording equipment in an exposed position, away from overhanging branches. Overhanging objects may obscure the calls as well as causing unwanted background noise.

What are the best conditions for nocmig recording?

The best conditions for nocmig are generally considered to be cloudy (which encourages the birds to fly lower) and calm. A change in wind direction is also thought to be a good cue for onset of migration. Position your recording equipment in an exposed position, away from overhanging branches.

What equipment do I need to record Nocturnal migration?

Freshly arrived migrants: Redwing and Song Thrush are very common nocturnal migrants particularly in Autumn. To start recording you will need to make a small investment in some sound-recording equipment. Essentially you will need a microphone and a device that saves the sounds which are recorded.

How do scientists track bird migration?

Scientists can now follow migrating birds by attaching lightweight electronic transmitters to them and tracing the signals. At first they used radio transmitters, but these stopped working when the batteries ran out. Today they use solar-powered satellite transmitters, which last much longer.

What kind of microphone do you use for recording?

I personally use the Olympus LS-12 recorder (see above) and a Sennheiser ME 66 shotgun microphone. The microphone is connected to the recorder with a XLR-Mini jack cable (plug the XLR end on the powering module of your microphone, and the Mini Jack end on the “external mic” part of your recorder.

How do birders detect bird migration?

Nevertheless in recent years the detection method has grown a strong following among European birders. The process involves the use of sound-recording equipment to capture the flight calls of migrating birds, then detecting and identifying the call signatures using computer software.

Can you identify bird calls in the spectrogram?

Identifying bird calls in the spectrogram against the various other obscure night time noises (barking dogs, squealing tyres, police sirens, fireworks) will take some practice. Also don’t be discouraged if you cannot identify every call – many will be too distant, distorted or unclear to successfully identify.

What is ‘nocmig’?

‘Nocmig’ (or Night Flight Call / NFC recording as it’s known in North America) is the nocturnal equivalent of visible migration watching, and typically employs sound recording equipment to capture the flight calls of migrating birds.

What are the best conditions for nocmig migration?

The best conditions for nocmig are generally considered to be cloudy (which encourages the birds to fly lower) and calm. A change in wind direction is also thought to be a good cue for onset of migration.

What equipment do NOC-MiG recordists use?

Most noc-mig recordists use a portable digital audio recorder. These have inbuilt microphones so the recorder can be left out all night (see here ).

Why can’t we track bird migration?

It’s difficult to track birds over their yearlong journeys and migrations. Scientists use the sun as a reference to figure out where these birds actually go! For thousands of years, people wondered where birds went for certain parts of the year.

What is the bird migration season?

Spring migration runs from approximately Mar 1-Jun 15th and fall migration from approximately Aug 15-Nov 30th. Birds can be impacted by light pollution on any night during migration, so going Lights Out the full migration season is optimal.

How do birds train for migrations?

Amazingly, this change to the flight muscles occurs without birds having to increase flight activity – birds don’t train for migrations through increasing exercise; they simply take off one day, ready to go. Fat deposition and energy conservation are vital aspects of the pre-migratory process.

What’s the best way to record wildlife sounds?

The Macaulay Library recommends choosing an app that lets you record uncompressed WAV files. That’s techno-speak for an audio format that provides the highest quality and most accurate copy of wildlife sounds. It’s also the format used by archives dedicated to long-term audio preservation.

How much does it cost to record bird sounds?

Most articles on recording bird sounds will try to convince you that you need lots of fancy recording equipment (fancy means expensive). They will suggest parabolic and shotgun microphones, recorders with phantom power, and microphone preamplifiers. A pro-level setup with two microphones and a recorder will set you back $4,000.

What’s the best microphone for recording nature sounds?

“The best microphone, at the end of the day, is the one that you have,” says Ben Mirin, a sound artist who remixes nature recordings. “Every moment of birdsong is fleeting and contains information.” Six recordists share how they captured specific clips and their go-to gear.

What kind of microphone do you use to record birds?

There are several styles of microphone you can use when recording birds: a handheld recorder/microphone combo like the Zoom H4N, a parabolic setup (a microphone with a parabolic dish), or a shotgun microphone. I chose a shotgun microphone for its highly directional recording (but not too directional!).

Can you record a bird that gives one call?

So when you press the “Rec” button just after you hear this Yellow-browed warbler (Phylloscopus inornatus) call, the call will in fact already be recorded. In other words, you can record a bird that gives a single call, even if you start recording after the call.

Can microphones be used as a recording device?

Microphones that are directional, like a shotgun microphone or a parabolic reflector, greatly improve the quality of your recordings even if you are using a smartphone as a recording unit. A smartphone is designed to capture loud sounds at close range, and you’re trying to pick up soft sounds from a long way away.

What is the best microphone for bird watching?

The Sound Shark parabolic microphone is ideal for capturing bird songs. The Sound Shark’s long range allows bird watching videographers to record their favorite birds from afar.

What equipment do you need to record Birdsong?

My Gear Setup: Birdsong Recording 1 Microphone. There are several styles of microphone you can use when recording birds: a handheld recorder/microphone combo like the Zoom H4N, a parabolic setup (a microphone with a parabolic dish), … 2 Shock Mount. … 3 Windscreen. … 4 Recorder. … 5 XLR Cable. … 6 Headphones.

What is a shotgun microphone used for bird recording?

Shotgun microphones are essentially long tubes with evenly spaced slits down the sides. The actual microphone is located at the base of the tube. They are designed to allow sound in from the front, and reject sound from the sides. Shotgun microphones are popular for recording birds because they allow you to focus on a single species.
