Observation details

Pair(s). Heard(s) and seen. Subspecies and/or taxon identified by size, shape, color pattern and/or sound. Male had a complete solid black cap surrounding the ear patch giving the cap a pointy claw-shape look to the corners at the sides of the neck, slaty back, whitish below, with grayish chest sides, black wings with inner white-webbed flight feathers, black short pointy bill and black tail with prominent white outer tail feathers. Female quite similar to male in overall plumage except by the narrow somewhat broken white spectacles (just to over the eye) joining with whitish lores and supraloral stripe. The bird was first heard at the higher parts of the scrubby slope, later on after use of PB, birds responded immediately and came quite close on exposed branches to investigate, and then both began foraging nearby on small bushes on lower part of the slope, making contact calls. Habitat: Pacific arid scrub with scattered cactus. Bird heard first at ca. 09:40hrs. and pair last heard and seen by 10:45hrs. Elevation ca. 2300 m. Audio recorded. (recordings after PB, and natural vocalizations). *Literature ("All the Birds of the World" book published by Lynx Edicions - Josep del Hoyo (Editor)) shows that female of Polioptila maior has a white narrow forehead which joins with white broken spectacles, which is the only noticeable difference with the female shown in the picture(s) taken by some members in the group, where the female has black forehead concolor with cap. These difference rise questions: Maybe a different subspecies isolated by geographic barriers or a hybrid between 2 taxa?.
