Datasets

Train

Exclusively using focal audio data from Xeno-Canto (XC) with quality ratings A, B, C and excluding all recordings that are CC-ND.
Each dataset is tailored for specific target species identified in soundscape files.
We offer detected events and corresponding cluster assignments to identify bird sounds in each recording.
We provide the full recordings from XC! These can generate multiple samples from a single instance.

Test

Only soundscape data sourced from Zenodo.
We provide the full recording with the complete label set and specified bounding boxes.
This dataset excludes recordings that do not contain bird calls ("no_call").
Task: Multiclass ("ebird_code")

Test_5s

Only soundscape data from Zenodo formatted acoording to the Kaggle evaluation scheme.
Each recording is segmented into 5-second intervals without overlaps.
This contains the "no_call" class.
Task: Multilabel ("ebird_code_multilabel")
