Celebrating World Migratory Bird Day in the Americas

By Catherine Lindell, Editor-in-Chief, Ornithological Applications

In honor of World Migratory Bird Day in the Americas on 9 October, we draw attention to some of the articles and blog posts about migratory birds that have been published in the AOS journal, Ornithological Applications (formerly, The Condor), the journal Ornitología Neotropical, and on AOS’s Wing Beat blog from 2019 through 2021. Given our changing world, migratory birds are particularly at risk because they traverse many different regions during their annual journeys. Generating information on their paths, their habitat preferences, and their survival helps guide conservation efforts to protect them. 

World Migratory Bird Day in the Americas is celebrated this year on 8 May (read our related blog post) in the U.S. and Canada, and on 9 October in Mexico, Central and South America, and the Caribbean. The articles we’re highlighting address topics ranging from the migratory patterns of shorebirds off the Atlantic coast of North America, to the importance of California’s Central Valley for migrants, to the potential consequences of climate change for intracontinental migrants in South America. We also include several articles about migrants published in Ornitología Neotropical, a journal that focuses on the biology of Neotropical migrant birds.

We hope this collection of important research serves as inspiration for you to learn more and get involved in conservation efforts for migratory birds.
