Uncovering the Secrets of the Blue Eared-Pheasant: Behavior Breeding & Demography

The Blue Eared-Pheasant, or Crossoptilon auritum, is a species of bird that belongs to the family Phasianidae. It is a ground-dwelling bird that is widely found in China, specifically in the western provinces of Tibet, Qinghai, and Gansu.

In this article, we will learn more about this fascinating bird from its identification, plumages, to molts.


The Blue Eared-Pheasant can be easily distinguished from other species by its striking appearance. The male has a blue-greyish head and a black throat that contrasts sharply with its white neck and back.

The upperparts and flanks have a rich red-brown color, while the underparts are black with white stripes. It also has a long tail with white tips and blue-grey undertail feathers.

Meanwhile, the female is smaller and less colorful than the male. She has a brown head and underparts with white stripes, while her upperparts are brown with black markings.



When identifying the Blue Eared-Pheasant in the field, there are a few key characteristics to look for. Size can be a good starting point, as the male is larger than the female.

However, it is the coloration that is the most useful identification feature. The male’s blue-gray head and black throat are striking, as is the contrasting red-brown of the body.

Additionally, the long, blue-greyish tail with white tips can be seen as the bird takes flight.

Similar Species

It is important to note that the Blue Eared-Pheasant can be easily confused with other similar species, such as the Himalayan Monal, Lophophorus impejanus. The Monal has a distinctive green head, while its body plumage is a more subdued brown color.

However, the two species do overlap in distribution, so careful observation is needed to tell them apart.


The Blue Eared-Pheasant has a unique plumage that changes as the bird matures. Juvenile birds have a brownish-grayish plumage with buff speckles.

Their feather tips also have a buff-white fringing. The immature bird’s plumage slowly turns to a more reddish-brown color for males and brown for females, and they begin to resemble adults after their second molt.


Crossoptilon auritum has two major molts: breeding and post-breeding. The breeding molt usually occurs in May and June, while the post-breeding molt occurs between August and December.

During the breeding molt, the male’s plumage becomes more vibrant, and there is a loss of some of the feathers on the wings and tail. During the post-breeding molt, the male’s feathers become duller, and the new feathers are less vibrant.

The female, on the other hand, does not undergo significant changes in plumage during either molting period. In conclusion, the Blue Eared-Pheasant is a fascinating bird species that can be found in western China.

Identification can be made based on their unique coloration, size, and distinct tail markings. The species undergoes two major molts, which affect the plumage of the males significantly.

Understanding the habitat needs and movements of birds is essential for their conservation, as it helps us identify measures to protect them and their environments. In this article, we will explore the habitat and movements of the Blue Eared-Pheasant, a ground-dwelling bird found in western China.


The Blue Eared-Pheasant is typically found in open coniferous and mixed forests with dense undergrowth, particularly in areas of scrubby, mountainous terrain. It is known to prefer altitudes between 2,500 and 4,500 meters above sea level.

The birds can also be found in grasslands, along forest edges, and in shrubby areas near streambanks. The species is typically found in regions with cold winters and cool summers, where the overall climate is strongly seasonal.

The birds are adapted to these conditions and are well-suited to surviving the extreme cold of the Himalayan winter.

Movements and Migration

The Blue Eared-Pheasant is known for its limited movements. The birds are typically non-migratory, meaning that they do not undertake regular long-distance migrations.

Instead, they remain within their home ranges throughout the year, only moving small distances between feeding, nesting, and resting sites. However, they do undertake short seasonal movements, such as vertical migration between higher elevations in summer and lower elevations in winter.

This vertical migration is driven by the availability of food and shelter as the seasons change. During the summer breeding season, the birds are found in the highest elevations of their range, where they build their nests and raise their young.

As winter sets in and food becomes scarce, the birds move to lower elevations to search for food and shelter. The Blue Eared-Pheasant is also known for its strong fidelity to its range or home range.

As such, the birds often remain in the same area throughout their lives, only moving short distances within their range. This fidelity is driven by several factors, including the bird’s attachment to its habitat, as well as the need to remain close to vital resources such as water and food.

During the breeding season, male Blue Eared-Pheasants become territorial and defend their chosen area against rival males. This defense mechanism consists of vocal displays, such as calls and songs, as well as physical intimidation, such as visible aggression.

These displays help the males establish their territory and attract females for breeding.


In conclusion, the Blue Eared-Pheasant is a non-migratory bird that prefers open coniferous and mixed forests with dense undergrowth in scrubby, mountainous terrain. The species is adapted to cold winters and cool summers in regions with a strongly seasonal climate, and as such, it is well-suited to survive in the Himalayan winter.

The birds undertake short seasonal movements, such as vertical migration between higher and lower elevations, but are strongly attached to their home range and will remain in the same area throughout their lives. Understanding the habitat and movements of the species is essential for its conservation, as it helps us identify measures to protect this unique and interesting bird species.
