Birdsong identification for iPhone and Android

Hold your phone up. Siskin names the bird.

Siskin listens to a call, shows you the sound as it happens, and names the species in seconds. Every bird you identify goes into your field journal, and it all works with no signal.

01 Listen

It hears what you hear.

Siskin listens through your phone's microphone in short windows. It filters out wind and road noise, then turns the sound into a spectrogram you can read as it draws: pitch going up the page, loudness as height and colour.

  • 10 sA rolling window, so you never miss the start of a call.
  • FilteredWind and traffic are reduced before anything is matched.
  • PrivateSound is not stored unless you choose to save a clip.

02 Identify

A name, a confidence, and the reason.

Siskin compares each call with 1,400 species and shows the three best matches. Tap one to see the part of the call it matched, outlined on the spectrogram, so you can check it against your own ear.

I stood in a marsh at dawn with no signal and it named a Virginia Rail from a single grunt. That was the day I paid for Plus.

The match view shows which part of the call it used. I check it against my own ear, and it has made me a better listener.

My journal has every bird I have heard since March, each with the place and the clip. I export it for the county survey.

08 Questions

Before you download.

Does it really work without a signal?

Yes. Once a region pack is on your phone, listening and identification run on the device. You need a connection only to download packs and to sync your journal.

Does Siskin record me?

Siskin listens only while the app is open and the listening screen is showing. Sound is processed on your phone and thrown away after matching. A clip is kept only when you tap save, and it stays in your journal on your phone unless you turn on sync.

How accurate is it?

On clear recordings of common species Siskin is right far more often than not, and it shows a confidence so you can judge. Quiet, distant or overlapping calls are harder, so it also shows the second and third matches. It is a good guide, not a final answer.

Which birds and regions does it cover?

1,400 species across twelve regions of North America. Each region is a separate pack, and the free plan includes one of your choice. More regions are added through the year.

How do I cancel Siskin Plus?

Open the subscription settings in your phone's store account and choose Siskin Plus. If you cancel, you keep Plus until the end of the year you paid for, and your journal stays on your phone.
