If you like to go to protected areas for birdwatching than you must know the eBird project, the world’s largest biodiversity-related citizen science project, with more than 100 million bird sightings contributed each year by eBirders around the world, a collaborative enterprise with hundreds of partner organizations, thousands of regional experts, and hundreds of thousands of users. PortugalAves is a collaborative project managed by the Sociedade Portuguesa para o Estudo das Aves. ATTENTION, DON’T REGISTER THE LOCATION OF NESTS.
