If you have searched for Golden-winged Warblers (Vermivora chrysoptera) in Vermont, chances are you have probably heard of Geprags Community Park in Hinesburg. This is arguably Vermont's most famous site to see Golden-winged Warblers, Blue-winged Warblers (Vermivora cyanoptera), and their hybrids, collectively known as the "winged-warbler" or Vermivora complex, after their genus name. Roughly 93% of winged-warblers reported to eBird in Vermont are documented at, or south of, Geprags Community Park, which has left the northern end of the Champlain Valley, the area above Burlington and west of the Green Mountains, underexplored. While over 90% of the northern Champlain Valley is privately owned, four publicly accessible locations annually host breeding winged-warblers: Colchester Pond Natural Area (Colchester), Aldis Hill and Hard'ack Recreation Area (St. Albans), Maquam Wildlife Management Area (Swanton), and Rollo and Ballard roads (Highgate).
