Ovenbird - Seiurus aurocapilla

Ovenbirds are easiest to age if pale tips to the tertials are present, indicating a HY/SY bird; otherwise rectrix shape is the best clue, but by spring some intermediates are not reliably aged. Determination of sex is generally limited to brood patch / cloacal protuberance during the breeding season

Quick Tips:

  • Look at the tertials - in fall HY birds have narrow rusty or pale tips (sometimes still present on SY birds in spring); absence of such tips is not a reliable indicator of AHY/ASY birds
  • Examine the rectrices - on HY/SY birds they are relatively narrow and tapered to a point, while on AHY/ASY birds they are more broad and rounded toward the tip
  • Consider the crown in fall - on HY birds the central crown stripe generally has little or no orange, while on AHY birds it usually has a moderate to substantial amount of orange
