Summary

  • Natural history: Wilson’s Warbler breeds across much of North America, but in Vermont it is essentially just a passing migrant. The species was confirmed nesting in the state only once, during the First Atlas near Bloomfield, and by the Second Atlas targeted searches of past sighting locations turned up no breeding evidence at all, suggesting that the singing males occasionally heard here in summer are likely non-breeding wanderers south of the species’ core range rather than a real local population. When a predator does approach an active nest, the female performs a broken-wing display, feigning injury to lure the threat away from her eggs or young.
  • Status in VT: Very rare breeder in northeastern corner of the state.
  • Data from other research: No additional data for VT.
  • Conservation status: State rank S1B
  • Other atlases: ON: 41%
  • VT’s role in North American range: The northeastern tip of VT is at the edge of the range.
  • Causes of change since first Atlas: No change.
  • Management/Monitoring recommendations: No current recommendations.
