Golondrinas de las Americas is a community of biologists dedicated to studying swallows in the genus Tachycineta from Alaska to Argentina, combining detailed studies of the breeding biology of the birds with standardized sampling of the swallows’ aerial insect prey. This network allows us to monitor the effects of weather and insect density on avian breeding on both short and long time scales at a hierarchy of spatial scales across the entire Western Hemisphere.

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
