Field Marks and
Identifying Characteristics:
Observed a female Black-throated Blue at Tonaquint Park near the nature center. I heard it s unique chip note in with flock of Audubon s Warblers as I entered the park (reminiscent of a junco). The warbler was gleaning moths from under the eaves of the building. I returned later in the afternoon and relocated it in the cottonwoods and willows closer to the parking lot.


Medium sized chunky warbler. Olive green upperparts and buffy yellow underparts. Face with dark eye and bright white lower eye arc and thin white supra loral stripe, dark lores, and grayish auricular patch. Wings with olive coverts, secondaries and tertials, and dark primaries with a small white fleck near the base of the outer primaries. Tail, underside pale and upperside dark, bluish green. Bill dark and legs pale.
