Unaccepted Records

One (2012-145) on 20 October 2012, Bossier: Red River NWR, Lake Bluff trail 0.6-0.7 mi. S headquarters unit (Bossier City). This remains a very difficult identification with many subjective pitfalls in the absence of knowing age and sex. The observer submitted a careful and detailed description but in the absence of a very detailed set of photographs, Members were unwilling to accept a single observer sight report as Louisianas third occurrence.

One (2013-096) on 28 December 2013, Cameron: Peveto Woods Sanctuary. The photographs were superficially suggestive of this species. However, two characters visible in the photos seemed to better favor Blue-headed over Cassin's: 1) bright, clean white under parts contrasting with yellowish sides, and 2) a fair amount of contrast on the upper parts between the gray crown/nape and the grayish green back. Relatively fresh fall/early winter Cassin's should show more uniform grayish-green upper parts, including the nape/crown area, with little or no contrast. This represents a difficult and subjective identification that prompted most Members to adopt a conservative stance and not accept the report. The are only two accepted state occurrences, both specimens from Cameron in early fall.
