SPEA is an Environmental not-for-profit organization whose mission is to support research and conservation of wild birds and their habitats, by promoting sustainable development for the benefit of future generations.
The Nocturnal Birds Working Group was created in 2007 due to the interest of some members of SPEA in this group of birds. Its aim is to promote the study and conservation of Strigiformes (owls) and Caprimulgiformes (nightjars) in Portugal.
