The data consists of mp3 files with unique IDs as file names, split into train and test sets and available as zip files in the downloads section. The labels for the training set are contained in train.csv, corresponding to one of the 40 species of bird listed below. Your task is to predict the labels for the test set, following the format in sample_submission.csv.

In cases where more than one species is calling (many recordings contain faint background noise) the labels correspond to the most prominent call, and your predictions should do likewise.

We are grateful to the many citizen scientists and researchers who shared the recordings which made this competition possible. The full list of authors can be found in authors.csv.
