The blue-winged teal (Spatula discors) is a species of bird in the duck, goose, and swan family Anatidae. One of the smaller members of the dabbling duck group, it occurs in North America, where it breeds from southern Alaska to Nova Scotia, and south to northern Texas. It winters along the Pacific and Atlantic coasts and south into the Caribbean islands and Central America.

Field-craft tips#

  • Winter is peak season for colourful drakes.
  • Morning side-light reveals iridescent head colours.
  • Get low to the water for an eye-level perspective; expose for bright plumage to avoid clipped whites.
  • Sightings peak in April, which is when you'll have the most chances.

Ethics#

  • The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
  • Stay on trails, respect closures around nests, leks, dens and haul-outs.
  • Avoid playback and baiting in sensitive seasons; never bait predators.
  • Don't share precise locations of rare, nesting or roosting animals publicly.
