One (1993-02) on 16 Apr 1993, Cameron: Little Pecan Island, approximately 30 mi. E of Cameron. The Committee agreed that the description did not rule out the larger, darker gray (but very similar in appearance) Appalachian subspecies of Blue-headed Vireo (V. solitarius alticola) or perhaps a very worn and dull nominate Blue-headed.
One (1994-125) on 31 Dec 1994, St. John the Baptist: Laplace. Although the description was suggestive of this species, members agreed that it was not detailed enough to support the identification.
One (2005-08) on 30 Jan 2005, Livingston: Springfield, Tickfaw State Park. All members agreed that the very brief description did not rule out Appalachian Blue-headed Vireo (V. s. alticola). The observer did not specifically mention this taxon in the “similar species” section of the report, suggesting unfamiliarity with this subspecies or its similarity to Plumbeous Vireo.
One first-year (2007-026) on 14 April 2007, Jefferson: Grand Isle, TNC Grilletta Tract. Although reported by a reliable observer, identification of vagrant “Solitary Vireos” is a serious identification challenge, especially during spring when individuals (especially first-year individuals) can be in worn/faded plumage. In this case of a potential second state (and first spring and SE Louisiana) occurrence, photos were not obtained, and the description did not convincingly eliminate a relatively dull and/or worn Blue-headed Vireo, notably the grayer Appalachian subspecies V. solitarius alticola.
There is only one accepted record of Plumbeous Vireo for the State, a specimen taken in Cameron 16 Sep 1984. Extralimital sight records of this species complex are extremely problematic, and every effort should be made to obtain photographic or specimen documentation.
