Migration in birds refers to the seasonal movements of thousands of species between breeding and wintering areas. Whether local as in birds from mountains descending to the plains or on the contrary taking them thousands of kilometers across seas and deserts, migration is a central process for a majority of species in temperate zones. In Europe, there is a vast diversity of migratory strategies, sometimes within the same genus, the same species, or even one and the same population.
Partial migration, more or less long-distance migration, sudden movements, dispersal, nomadism: birds are constantly moving, and finding global patterns from this complex canvas has been a challenge for ornithologists for centuries. How did all of these strategies emerge over the course of evolution, and what consequences do they have on the diversity and distribution of species? Understanding the mechanisms that make these movements possible is another challenge: what adaptations to orient yourself, manage your moult, optimize the flight, make reserves? How to better protect these populations so mobile across borders? So many questions remain open, helping to make migration a subject of inquiry and study for thousands of enthusiasts.
The “Migration” conference dedicated to the study of migratory avifauna, which will take place on November 27 and 28, 2020 in the form of a series of online conferences (due to health constraints) given by specialists, will present the recent research results on this topic. Combining scientific standards and popularization, this conference is accessible to everyone, amateurs and professionals alike, and completely free. It is organized by LPO France, with the support of the Muséum d’Histoire Naturelle de Paris, the Ministry of Ecological and Solidarity Transition and the French Office for Biodiversity, and with the help of volunteers from the LPO Ile-de -France.
