Near midday, Carl Jackson alerted us to its presence at the “waterfall” by the lobby entrance. It played peek-a-boo with us for 20 minutes as it foraged in this densely planted area, then flew north, over the pond, to the plantings adjacent to the lawn, btw the ponds and bungalow area. These plantings are more widely spaced and offered great viewing opps over the following 20-odd minutes. This is an active ground foraging Geothlypis warbler. Its counter-colored plumage in olive and yellow made it hard to spot amidst the deep shade and undergrowth it frequented. Its plumage is medium-to-dark olive above, with brighter yellows below, plus black accent marking that frame its crown, face and throat. The face is strikingly marked with a clear yellow loral stripe that continues over, behind, and below the eye that generates the impression of an incomplete yellow “spectacle” with notable bulge behind the eye. The yellow lower rim of the "spectacle" terminates against a broad blackish mark that fills the lower quadrant frontal to the eye. This blackish mark extends downward starting at the base of the bill and below the lores. It continues downward while angling slightly rearward, forming a broad frame the the throat. This near black mark sharply confines the bright, clear yellow throat, while smearing broadly rearward to blend somewhat into the olive and yellow tones of its body. Taken together, the black forehead, yellow loral stripe with near complete yellow spectacles, and bright yellow throat offset in black create a striking pattern when viewed face-on. On the crown, the blackish feathers from the forehead thru mid-crown are marked with a smattering of gray sprinkles that soften the transition to dark olive on the hind crown and nape. Analogously, the transition from dark-olive upperparts to yellow-olive underparts is soft, with the brightest and clearest yellows confined to the throat, lower belly and undertail coverts. The legs and toes are pinkish. The bill was of modest length and build, bluntly pointed, and mostly dark with paler tones basally below. The eye was dark. Foraging beat was confined to deep shade and directionally erratic. It moved with a sequence of short hops interspersed with picking motions directed at the ground, or in any direction at the immediately surrounding vegetation. Stops were frequent but very brief. It moved up into the vegetation several times, picking as it went, sometimes calling actively as it climbed. It also called from the ground. Calls were delivered individually or in a sequences of several closely space calls over 5-10 seconds. It also remained silent for several to many minutes while in view. To my ears, the call was a full, rich, more “rounded” note compared to the call note of YEWA that is most familiar to me.
