Battered live oak chenier woodlot with a handful of sugarberries (hackberries) and a couple honey locusts.Thicker understory than adjacent woodlots loaded w/ ragweed stalks and other weedy plants.

Behavior of bird:

May or may not have responded to mobbing tape, but appeared in canopy of leafless sugarberry to my left, but soon moved to an obstructed perch in the canopy of an adjacent one where it began foraging on the overripe fruit.I then used playback to coax the bird into view for photo documentation, but it didnít exactly cooperate and continued to move about b/w the canopies of the live oaks all the while aggressively singing and chattering.


Mostly black upperparts w/ bright orange underparts.Black upperparts disrupted by bold white wing patch and remix edges.Head, including cheeks and supercilia, was bright orange as in underparts w/ black crown, nape, eye line, chin, and throat.Rump and tail predominantly orange w/ black tip to on tail (incl. corners).Thin, pointed bicolored bill (black upper, bluish-gray lower).Legs dark grayish.


Whistled song and husky chatter calls given in response to playback.Song w/ chatter-like intro notes followed by whistles; che chee che godee godee.

Similar species:

Mostly black upperparts, in particular forehead to nape, w/ bold white wing patch eliminates nearly all other orange and black orioles.Similar Baltimore Oriole eliminated by bright orange face and supercilium, bold white wing patch, orange-based black-tipped tail, and slightly brighter orange underparts.
