Light conditions (position of bird in relation to shade and to direction and amount of light):	Clear sky with optimal late morning sunlight. Sun angle high and behind observer. Backlighting or glare not a factor.
Optical equipment:	Zeiss Victory FL 8x42, Kowa TSN 881 Angled 88mm scope w/ 20-60x optical zoom, Canon Powershot SD1100 IS digital camera (all equipment in excellent condition).
Distance to bird(s):	within ca. 10-15 meters
Duration of observation:	~75+ min. total
Habitat:	Heavily disturbed, fragmented chenier ridge forest with scattered mature live oak mottes, hackberry-tallow-acacia scrub, dense early successional herbaceous understory (baccharis-ragweed-goldenrod-camphorweed, etc.), unimproved pasture, rural residential.
Behavior of bird:	Actively moving through and foraging in high canopy with mixed-spp. flock of wintering passerines. Perching relatively high, conspicuously on open, exposed branches for prolonged periods. Responsive to playback. Very vocal throughout encounter.
Description:	A rather drab oriole with gray upperparts and paler gray-white underparts. Brighter yellow-orange on head and especially face with most intense color at malar. Ghost pattern of male facial features quite obvious, showing darker eye line (transocular stripe) and brighter yellow supercilium. Grayish-yellow vent/undertail coverts. Two white wing bars with crisply white-edged wing coverts and flight feathers. Relatively short, yellowish-gray tail. Darker blue-gray upper mandible (maxilla) and pale horn-flesh lower mandible. Grayish legs and feet. Dark brown irides. Presumably first-winter (first basic) individual by less-defined wing bars, slightly duller plumage, and extensively pale lower mandible.
Voice:	Series of short chatters and sweet, drawn-out kleek. More squeaky, higher-pitched quality than Baltimore Oriole.
Similar species:	Female-plumaged Baltimore Oriole (Icterus galbula) can be eliminated by extensive white in median/greater wing coverts, broader white-edged flight feathers, duller gray-white underparts (lacking warmer orange wash on breast), darker eye line, brighter yellow supercilium and malar, and vocalizations.
Photographs or tape recordings obtained?	Digiscoped photos by Devin Bosler. Yes, photos attached.
Previous experience with this species:	Very familiar with this species. Observed in all Western states where they occur. Plus, observed on two occasions in PA, both coming to artificial nectar feeders during winter. In addition to multiple individuals in LA (Orleans and Cameron Parishes).
