Dear all,

We cordially invite you to participate in the 2019 edition of the LifeCLEF Bird Recognition challenge ( LifeCLEF is part of CLEF 2019 (, a conference to be held in Lugano, Switzerland, 9-12th September 2019.

The LifeCLEF consortium aims at evaluating and improving the efficiency of fully-automated algorithms tackling large scale biodiversity problems.

The goal of the LifeCLEF Bird Recognition challenge is to detect and classify all audible birds within a set of soundscape recordings. The training data contains ~50,000 recordings taken from and covers 659 common species from North and South America. The test data contains soundscape recordings from two regions: (i) ~280h of data recorded in Ithaca, NY, United States and (ii) ~4h of data recorded in Bolívar, Colombia. Each test recording contains multiple species and overlapping vocalizations. Both sets include extensive metadata and ~80,000 expert annotations provided by the Cornell Lab of Ornithology ( and Paula Caycedo. If you are interested in bioacoustics, avian monitoring and/or machine learning, we invite you to participate in this challenge.

Please check out this website: for more information.

The results will be published in the CLEF Labs Working Notes and presented at the CLEF 2019 conference in Switzerland. Other related conference contributions are welcome as well.
