Millions of birds migrate at night across the Earth. However, the nocturnal migration remains a little-studied phenomenon due to the complexity of tracking birds at night and identifying them only by sound. Every night, researchers and ornithologists record continuous migratory activity to better understand this phenomenon. This represents a huge amount of data to process.

Current methods of analyzing nocturnal bird migration data are therefore very time-consuming and the valuation of this data remains an area accessible only to experts. The main issue of this challenge is to find how to store the data and to automatically analyze the recording hours by identifying the sequence of interest, extracting it and making it corresponding to a species.

To address this issue, we are following the following steps:

• Develop a web application for birdwatchers to manage their annotations.
• Create and structure a database to store audio file annotations and URLs.
• Find and share codes to detect bird songs, classify sounds and identify bird species.
• Create an automatic processing platform.

At this time, we have created the database that is increasingly powered by our contributors, we also start to develop our web application. Of course, we are always open to new proposals or help that you could give us!
