The Golondrinas de las Americas project was supported by an NSF Partnerships in International Research and Education grant from 2007 through 2012. The project established nest-box populations of Tachycineta swallows at many sites throughout the Americas, and it catalyzed international connections and collaborations that continue to the present day. With its support, 48 US students worked with 21 foreign students at 13 international sites studying eight species from Canada to Tierra del Fuego. Though this site has not been maintained since 2012, we urge you to contact David Winkler, Dan Ardia, or Justin Proctor if you have further questions about doing research in this wonderful system.

We are an international community of biologists studying swallows in the genus Tachycineta from northern Canada to Argentina. Supported by the National Science Foundation, we are using standarized protocols to better understand the breeding biology of the Golondrinas de las Americas -- the swallows of the Americas -- and their aerial insect prey. Our network of biologists monitors the effects of weather and insect density on avian breeding at different latitudes across the Western Hemisphere and we are pursuing studies of geographic variation in many aspects of swallow biology.

This long-term, correlative monitoring has obvious merit for studies of:

  • global change
  • differences between tropical and temperate ecosystems
  • tropical-temperate life history difference in birds and insects

If you are interested in working with us or have questions about the Golondrinas de las Americas, please contact the project's founder, David Winkler, or Lori Sonken, project coordinator.
