Neotropical Flyway Project

 

Status – current

Overview

The populations of many Neotropical migratory birds have shown persistent declines in recent decades and species that were considered common just 40 years ago are becoming increasingly scarce. Migratory birds are fundamental to ecosystem function globally and they provide us with many essential services such as pest control and seed dispersal, reason enough to try to reverse these declines. To do this, we must first understand the complex life cycle of these birds in order to understand their needs and to be able to determine where and when populating limiting processes occur.

Close to 300 species of migratory landbirds, whose combined populations represent more than one billion individuals, migrate between the Neotropics and North America. Many species make an annual round trip of more than 10,000 km and, often, it is those species that migrate farthest that are disappearing quickest. Of all the periods of the life cycle, migration is the least understood and, yet, at the same time it is when the majority of mortality occurs. To fill this critical gap in our knowledge of the needs of migratory birds, the Neotropical Flyway Project will work in six countries in Central and South America in order to identify migration routes, key stopover or staging regions where the energy for migration is obtained, and the relative quality of the different habitats used.

Key Findings and Achievements to date

  • In March 2016, 9 biologists and birdwatchers from Colombia were trained in the identification and monitoring of migratory birds during a week-long training course.
  • During spring migration (March-May), the team surveyed 242 transects on 4104 occasions covering 16 sites located throughout northern Colombia.
  • The team recorded 14,090 migratory birds through transects and 163,288 during visible migration counts belonging to 71 species.
  • Initial findings include the discovery of previously unknown stopover regions where species like the Yellow-billed Cuckoo and Bay-breasted Warbler attain the energy they require in order to undertake their spectacular migrations.
