Ianthocincla ocellata Life habits and morphological characteristics

Male and female eye-striped thrushes have similar plumage. The forehead, top of the head and nape are black, the front of the eyes, the eyebrow and the chin are tea yellow or light brown, and the eyebrow behind the eyes is sometimes a mixture of blue-gray and black. The ear feathers are chestnut, the skin is yellowish brown or black.
The upper body is brownish brown, and each feather has a black subterminal spot and white or brownish white dotted terminal spots. Sometimes the upper back is brownish yellow with a wide black subterminal horizontal spot. The rest of the upper body is brownish brown with white terminal spots, and the secondary coverts are chestnut with black subterminal horizontal spots and brownish white terminal spots; the inner flight feathers and coverts are the same color as the back. The primary coverts are chestnut with white terminal spots and black sub-terminal spots, and the flight feathers are dark brown with white terminal spots. The outer vanes of the outer

Ianthocincla ocellata Distribution range and habitat

Distributed from the western Himalayas to northeastern Myanmar, including Nepal, Bhutan and northern India. In China, it is distributed in southern Gansu, western Hubei, Sichuan (central, western and northern), Yunnan (northeast, west, northwest) and southern Tibet.
The Eyed Laughingthrush mainly inhabits dense mountain forests such as mixed woods at an altitude of 1400-3100 meters, subtropical evergreen broad-leaved forests (the subtropical region is affected by the Qinghai-Tibet Plateau, and the marine monsoon becomes the source of water vapor in the region. The southeast is humid and rainy, but also relatively warm. The further northwest, the stronger the continental nature of the climate, the gradually lower the temperature, and the gradually reduced precipitation, showing a climate characteristic of transition from warm and humid to cold and dry) and mixed coniferous and broad-leaved forests (mixed coniferous and broad-leaved forests have four distinct seasons, with hot and rai

Eye-striped Laughingthrush often moves in pairs or small groups, mostly moving and foraging among the bushes under the forest or on the ground, and occasionally making calls of "Kagui, Gui, Gui..." During the breeding period, it makes beautiful, pleasant and varied calls, which sound like a continuous "Shiwei, Shiwei, Shiwei..."

The Eyed Laughingthrush mainly feeds on insects and also on plant fruits. Most of the plant fruits are fleshy drupes, pears, berries and cones, which are usually brightly colored when ripe. The main ways for birds to eat fruits are: ① directly nibbling fruits on the tree crown or nibbling fallen fruits under the tree, sometimes biting out the seeds after nibbling; ② taking the fruits from the tree and swallowing or pecking them at the perch; ③ grinding the fruit skin and only eating the seeds inside), seeds and grass seeds, especially in the non-breeding season, mainly feeding on plant food.

The Eyed Laughingthrush is found in the coniferous and broad-leaved mixed forest belt at an altitude of 2000-2600 meters in the Wolong Nature Reserve in Sichuan in summer. On May 14, 1984, a nest of this bird was found in Yingxionggou in the area. The nesting site is a flat terrace with an altitude of 2,400 meters. It is surrounded by artificial young forests and shrubs of Sichuan redwood. There is little human interference and good concealment conditions. The nest is built on a spruce sapling 7 meters high, 3.5 meters from the ground. It is shallow bowl-shaped, with a height of 120, a depth of 50, an outer diameter of 200, and an inner diameter of 110 mm. The parent bird twists three branches and crosses them between two thick branches as the nest base, and uses tree roots, branches, grass stems, etc. with a thickness of about 4-6 mm to build a platform shape, and uses short tree roots, branches, and grass stems to build a shallow bowl shape, with fibrous roots inside. There are two eggs in the nest, which are oval and pure blue. The size of the two eggs is 33×22 mm. At that time, the parent bird was incubating eggs and had poor nesting habits.

On May 27 and 28, two chicks hatched successively; the incubation period is estimated to be 16-18 days. The male and female parents jointly take care of the chicks. After the chicks are 7 days old, their feathers gradually become fuller and their food requirements increase rapidly; the time the parents spend warming the chicks gradually decreases, and the time they spend foraging increases accordingly. At 7 days old, the parents generally feed them every 1-2 hours; I have seen a chick open its mouth continuously to beg for food even when there is no parent feeding it. During the brooding period, the parents take turns to guard the nest area. The brooding period is 19-20 days.

The body of a 1-day-old chick is tender and flesh-red. At 4 days old, the whole body is flesh-red; the down feathers are clustered; the feather buds are slightly exposed. At 6 days old, the body feather buds are released; the eyes can be slightly opened; the bare area is purple-red. At 8 days old, most of the upper body has been feathered; eyes are fully open. At 11 days old, the upper body is fully feathered; white spots appear on the wing feathers. At 13 days old, the top of the head is gray-black; white spots appear on the upper back feathers; the lower back is brown; the claws have strong grip. At 15 days old, except for the head, the down feathers have disappeared; the base of the throat feathers turns black; the ear feathers are brown. At 17 days old, it stands on the edge of the nest all day; the upper beak is dark brown; the lower beak is brown at the end. At 19 days old, chick No. 1 leaves the nest; chick No. 2 can flutter and jump on the ground. At 20 days old, chick No. 2 also leaves the nest.
