Colombia has a great opportunity to implement lucrative and environmentally friendly tourist offers based on bird watching, because this is a country where a large number of species inhabit. With this type of tourism, the development of remote regions and affected by the armed conflict could be promoted. The objective of this work is develop an application for smartphones that facilitate and improve the experience of sighting in inexperienced tourists and encourage this practice in sun and beach tourists. The application has the ability to identify birds from their song. For this, a frequency analysis is carried out to characterize the sound by identifying the lowest frequency, the highest frequency and the four frequencies with the greatest intensity. For identification, the bandwidth of the song and the Euclidean distances between the vector containing the characteristic information of the song and the database with the information of the song of the registered birds are evaluated. The application has an assertiveness in recognition of 79% and a potential for success of the service in its commercialization and use of 68%. It can be concluded that it is possible to develop an application for the recognition of birds using the song, computationally light, efficient and successful that can be executed in devices with low technological features
