GOOGLE PLAY DESCRIPTION
Bird Song Id helps you identify a wide variety of birds of the British Isles by their songs and calls.

Record a bird singing and use Automatic Recognition to help identify it.

Automatic Recognition is a little like Shazam for birds.

Automatic Recognition takes place on the device, no connection to the internet or mobile network is needed.

Automatic Recognition needs good quality recordings to work well. See the help below, or follow the Developer Website link to find out how to improve your recordings.

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 of Bird Song Id to be 85%.

--------------- HELP ----------------
Automatic Recognition needs a good quality recording of the bird.
-------------
Only record when it is very quiet, apart from the bird singing of course.
-------------
Be close to the bird singing, as close as you can be without disturbing it.
-------------
Only record when a single bird is singing, or when a single bird is dominant
-------------
The analysis graph should have plenty of blue and green colors with few or no black peaks.
-------------
The peaks on the Bird Song Id 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 Bird Song Id 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
-------------
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
-------------
The microphone is often at the bottom of a device, point the microphone towards the bird
-------------
Remove the case from your device 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
-------------
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 edited (inter phase gaps are often shortened). They sound very different to recording birds for real in the natural environment. Particularly true for finch and warbler recordings.
-------------
Some devices, particularly larger tablets, do not have good microphones built in to them. This will result in a lot of background hiss that will cause Automatic Recognition to fail. Better external microphones are usually available for these devices.
-------------
Get to know the warble of a warbler, the chatter of a finch, the chirp of a sparrow, the song of a blackbird etc etc !
