About Pseudoseisura gutturalis (Orbigny & Lafresnaye, 1838)
The white-throated cacholote (Pseudoseisura gutturalis) is 22 to 23 cm (8.7 to 9.1 in) long and weighs 63 to 79 g (2.2 to 2.8 oz). It is one of the largest furnariids and has a small crest. The sexes of this species share the same plumage. Adults of the nominate subspecies have a white eyering and lores, with the rest of the face being dark brownish gray. The crown and upperparts are also dark brownish gray. The wings are mostly the same dark brownish gray, with slightly paler edges on the coverts and flight feathers. The tail is dark fuscous gray with slightly paler feather edges, and the feather tips have few barbs. The chin and throat are white, with black coloring at the bottom of the throat. The breast and belly are a paler brownish gray than the back; many of these feathers have grayish white tips, which create a "frosty" appearance. The vent area and undertail coverts are slightly paler than the breast and belly. The iris ranges from yellow to creamy-buff or dark brown; the maxilla is dark gray, the mandible is pale bluish with a dark gray tip, and the legs and feet are gray. Juveniles have light mottling or barring on their underparts. Subspecies P. g. ochroleuca is paler and more sandy in overall coloration than the nominate subspecies. Of the two subspecies, P. g. ochroleuca is the more northerly one, found in northwestern Argentina. The nominate subspecies occurs in central Argentina. The geographic dividing line or overlap area between the two subspecies is unclear. The species inhabits generally barren landscapes, including arid scrublands in lowlands and montane valleys. In the northern part of its range, it also occurs in woodlands dominated by Prosopis. Its elevation range extends from sea level to 2,900 m (9,500 ft).
