Automatic Recognition

Bird Song Id includes an early version of our Automatic Recognition feature. Automatic Recognition takes place when you analyse a recording of your own. No connection to the internet or mobile network is needed, Automatic Recognition takes place on your device.

Automatic Recognition gives you a list of birds the recording could possibly be of, with percentage likelihood of each. Take note of the percentages given, it will give you a good indication of how sure the system is that the species is correct. A difference of 10% between species is quite small so listen to the samples carefully to determine which is correct. A difference of 20% or more indicates a good level of confidence.

How successful is it ?

Our aim is to get the correct bird in the top three of those listed. In our testing of over 1,000 samples we found the success rate to be 85%.

Automatic Recognition needs a good quality recording of the bird. Therefore:

The analysis graph should have plenty of blue and green colors with few or no black peaks. See the example below.

The peaks on the graph should reach all the way to the top. Low peaks indicate poor quality and recognition is unlikely.

The Audio Quality, shown at the top of the results screen, should be at least Good, and preferably Very Good or Excellent

The highest score should be above 70% to be useful. Below this and the system is telling you it is not sure what the song is.

A difference between two birds of less than 10% is not that significant, so listen to the samples from both to help you further

See the samples for how the analysis graph should look (to see the samples press the sample button at the top right of the help page)

Make sure it is very quiet apart from the bird song which should be nice and loud

Be as close to the bird as you can be without disturbing it

Be patient, dont expect miracles, the system works but needs good clear recordings

Find the microphone on your device. Point the microphone towards the bird

Remove the rubber case from your phone or tablet if you use one as this can dampen the microphone

Record a single bird at a time

Capture at least two singing episodes if you can. Record for the full 30 seconds if possible

Avoid windy conditions. Air moving over the microphone will mask the bird sounds

Make sure there is plenty of life in the battery. Your device will reduce power going to the microphone as the battery runs down

Playing songs to the app from recorded material on the internet, other apps or CDs is unlikely to work as this material is digitally processed and sounds different to our app from real birds in the natural environment

Graph for Auto Rec

Automatic Recognition will help identify a good cross section of bird song, but you will need a good quality 30 second recording of the bird. The song needs to be one covered by the app.

Lots of blue and green peaks reaching to the top of the analysis graph is a good indication of a quality recording. There is help in the app, and examples to give you an idea of the quality needed.
