Useful Hints

  • Violet-green Swallows commonly nest in small colonies of up to 25 nests, but isolated pairs have been reported nesting in dead trees, especially near lakes and streams.
  • The female is the primary nest builder and can take from six days to three weeks.
  • During egg-laying and incubation, the male brings feathers with which to line the nest.
