Description

The tufted tit-tyrant is a small bird, averaging 9.5 to 11 centimeters (3.7 to 4.3 in) in length and weighing about 6 grams (0.21 oz). Its long, recurved crest is typically conspicuous and is often parted, giving the impression that the bird has two crests. The crest's feathers are black and emerge from the center of the bird's black crown, although occasionally there is a small patch of white hidden by the crest. The head is black overall with a white supraloral and postocular stripe. The bird's iris is creamy white to pale yellow and the bill is black. This tit-tyrant's back is a dull, grayish brown, and the wings and tail are a duskier shade of this color. The wings also feature two narrow white wingbars, while the outer tail feathers are white. The throat and breast are white and covered in dark gray to black streaks, which thin out further down the breast and along the sides. The belly is a pale yellow which fades as the plumage becomes more worn, while the bird's legs are black. Males and females are similar in appearance, although females are typically smaller and may have smaller crests. Juvenile tufted tit-tyrants are duller in coloration and have a shorter crest; the juvenile's wingbars are also buffy and there is no hidden white spot on the crown. There are few variations in plumage between the three subspecies. Anairetes parulus aequatorialis tends to be browner than the nominate subspecies in its upperparts, with broader and more extensive breast streaks and broader and more distinct white wingbars. A. p. patagonicus has more variation from the nominate subspecies as it is paler gray overall, particularly on the crown, and the wingbars and breast streaks are broader and more distinct. A. p. patagonicus's underbelly is also a paler yellow to white. This flycatcher has a loud, high-pitched song. It is also known to give a fast chuit-chuit-chuit-chuit-chuit-chidi-didi song, and occasionally single notes of chuit are made in a slow series of calls. When foraging in pairs, tufted tit-tyrants have been observed using a perr-reet call to stay in contact with each other. The species' contact call has been described as a pluit-pluit. The tufted tit-tyrant is also known to give a long, weak trill.

Feeding Habits
Tufted Tit-tyrant primarily consumes insects, occasionally seeds. It forages actively, often in pairs or family groups, throughout all strata of its habitat, using a mix of strategies including gleaning, hover-gleaning, and flycatching. Unique adaptations include leapfrog-style feeding within pairs and tail flicking while hunting in specific shrubs.
Habitat
The tufted tit-tyrant has been recorded in Colombia, Ecuador, Peru, Bolivia, Argentina, and Chile. It is mostly restricted to the Andes mountains throughout the northern portions of its range, while in the south its range broadens to include the coast. It has also been recorded as a vagrant in the Falkland Islands. It is the most abundant and widely distributed of the tit-tyrant species. Its preferred habitat is upper montane forests and shrublands. Despite this preference, it is a habitat generalist and is also found in elfin forest, the edges of cloud forests, Polylepis woodland, brushy forests with Chusquea bamboo, disturbed humid scrub, temperate forests, and dry thorn scrub. It seems to move back into fire-stricken areas at a normal rate for páramo birds, neither colonizing recently burned areas nor waiting for the area to completely recover. This tit-tyrant is most frequently found between 1,800 and 3,500 meters (5,900 and 11,500 ft), though it can be found at sea level in Chile and up to 4,200 meters (13,800 ft) in the Andes.

Behavior
This tit-tyrant appears to be territorial in defending what it regards as its feeding territory, although it only displays territorial behavior against other tufted tit-tyrants. Birds defending their territory, either alone or in a pair, tend to begin their defense by calling rapidly and displaying displacement behavior, such as bill wiping or wing flaring. They then raise their crest and chase the other tit-tyrant through the shrubs, occasionally physically attacking the intruder. The victorious tit-tyrant then returns to its normal foraging behavior. The southern subspecies, A. p. patagonicus, migrates to northern Argentina after the breeding season; the other populations appear to be non-migratory.

Species Status
The tufted tit-tyrant is listed as Least Concern because of its large range of 2,640,000 km (1,020,000 sq mi) and stable population, which, although not officially estimated, is believed to be well above 10,000 individuals. It is uncommon to locally common throughout its range. This species is considered to have a low sensitivity towards human disturbances in its habitat.
