Song Sleuth turns your iPhone or iPad into a powerful bird song identifier for the U.S. and Canada. Developed by Wildlife Acoustics, in collaboration with the world-renowned bird expert and illustrator David Sibley, the app features the ability to automatically recognize the songs of the 200 birds most likely to be heard. With Song Sleuth, birders and nature enthusiasts can record bird songs and view likely matching species on the spot with unprecedented accuracy. Wildlife Acoustics’ identification algorithms are the result of over a decade of research and practical experience designing professional bioacoustics recorders and software.

AUTOMATICALLY IDENTIFY SINGING BIRDS
Just press the record button when you hear a bird singing and Song Sleuth will begin recording a few seconds back in time from the built-in microphone. You can watch a visual representation of the frequencies and timing of the bird’s song on the real- time spectrogram. Tap the record button again when the song is complete to stop the recording and the LIKELY MATCHES screen will immediately show you the top three species matches.

You can listen to your recording and the example recordings of the most likely bird matches as well as compare their spectrograms side-by-side using Compare Mode. This is an invaluable tool to help determine the correct bird or just to learn more about birds’ songs and their endless variations.

Auto identification is not perfect. It can't identify simple chips, only more distinct calls and songs. It can be confused by noise such as wind, clothing and other birds. You may need to edit your recordings for best results. This app is intended to be interactive and fun to learn about bird song. If you will be disappointed to see the wrong answer, then this app isn't for you. For more tips see www.songsleuth.com.

VIEW AND LISTEN TO RECORDINGS
Recordings are saved as standard .wav files for later analysis on a computer or to view in the app. You can view the recording’s spectrogram, listen to the recording, add text notes, speed up or slow down playback, and loop the recording to listen repeatedly. You can also trim the recording or selectively filter to hear only some frequencies just by zooming in to the desired range.

INCLUDES THE DAVID SIBLEY BIRD REFERENCE
Song Sleuth allows you to learn more about the bird species via The David Sibley Bird Reference. The reference includes illustrations of each bird singing, painted for the app by David Sibley. The reference also gives you details about each bird and its songs and shows a range map for the bird. The map shows your current location and allows you to pan and zoom or to change from map to satellite views. These are map features unique to this app. Also exclusive to Song Sleuth is a bar chart showing the likelihood of each bird’s presence in your area throughout the year, using David Sibley’s extensive database of bird presence.

COMPLETE COLLECTION OF EXAMPLE RECORDINGS
Well-known nature recordist Lang Elliot and friends spent countless hours in the field with sophisticated recording equipment to provide over 1,000 world-class recording examples of the included bird species. The collection includes not just the main song of the bird, but many song and call variations for that species.

SEE YOUR RECORDING LOCATIONS
Recording locations can be viewed on a satellite or road map. (An external Bluetooth GPS is necessary if your device does not have GPS built-in.) Identified birds are shown using a 6-letter species code on the map so you can see where you have recorded each species. You can open the recording right from the map. Recordings can also be transferred to your computer in a KML file that allows the location to be viewed in Google Earth. (Continued use of GPS running in the background can dramatically decrease battery life.)

SHARE RECORDINGS OR TRANSFER TO PC
Recordings can be shared with other Song Sleuth users via text messaging or email.
