{"url":"/dataset/clo-43sd","name":"CLO-43SD","full_name":"CLO-43SD","description_markdown":"**CLO-43SD** is a dataset for multi-class species identification in avian flight calls. It consists of 5,428 labeled audio clips of flight calls from 43 different species of North American woodwarblers (in the family Parulidae). The clips came from a variety of recording conditions, including clean recordings obtained using highly-directional shotgun microphones, recordings obtained from noisier field recordings using omnidirectional microphones, and recordings obtained from birds in captivity.\n\nSource: [https://wp.nyu.edu/birdvox/codedata/](https://wp.nyu.edu/birdvox/codedata/)\nImage Source: [https://www.allaboutbirds.org/a-rosetta-stone-for-identifying-warblers-migration-calls/](https://www.allaboutbirds.org/a-rosetta-stone-for-identifying-warblers-migration-calls/)","description_withheld":null,"homepage":"https://wp.nyu.edu/birdvox/codedata/","introduced_date":null,"introduced_date_note":null,"introduced_by":null,"license":null,"modalities":[{"name":"Audio","url":"/datasets/modality/audio"}],"tasks":[],"languages":[],"variants":["CLO-43SD"],"data_loaders":[],"num_papers_in_archive":0,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
