The global ecology of bird migration: patterns and processes

Abstract

Nearly 20% of bird species are migratory, their seasonal movements radically changing avian community composition across the world. In this talk, I will present a global macroecological analysis of bird migration. First, I mapped global patterns of the distribution of migratory birds, revealing strong spatial features. I then used these patterns to test hypotheses about the processes driving this phenomenon. The results paved the way for a mechanistic model which successfully explains the patterns previously described and has been used for reconstructing the global seasonal distribution of birds back to the last ice age.
