Conclusion
This chapter summarizes the book's main points concerning the ecology, life history, and evolution of migratory birds. It first considers migration as a behavior used to exploit geographically separate environments that differ seasonally in their value for survival and reproduction. It then discusses the avian migrant's breeding period, postbreeding period, fall transient period, wintering period, and spring transient period. It also reviews the avian migrant's population ecology, evolution and biogeography, and its role in the movement and spread of pathogens such as West Nile virus (WNV) and avian influenza, along with the relevance of avian migrant “connectivity” to conservation. Finally, it reflects on the issue of migrant origins and migration as a life history strategy.
Keywords: life history, evolution, migratory birds, migration, breeding, population ecology, biogeography, pathogens, connectivity, conservation
