Confirming a european starling

  • A very short square tail with a long pointed bill — the shape is diagnostic in flight.
  • White spotting in winter, glossy and nearly plain in summer.
  • Bill turns bright yellow in the breeding season.
  • Walks rather than hops.

Confirming a brown-headed cowbird

  • A short, thick, conical bill — finch-like, not the long pointed bill of a blackbird.
  • Male: black body with a chocolate-brown head, which can look black in poor light.
  • Female: uniformly plain grey-brown, no pattern, faint streaking below.
  • Tail is short relative to other blackbirds.
