The Koromandeluhu ( Bubo coromandus ) is a species from the family of real owls. It occurs in South and Southeast Asia .
features
The Koromandeluhu is a relatively large species of eagle owl. It reaches a body length of 48 to 53 centimeters. The body plumage is grayish to sooty washed out. The eyes are yellow. The feather ears are very noticeable, stand upright and relatively close together. The face veil has a narrow dark border. The barrels are feathered.
There are possibilities of confusion with the Bengalenuhu , since the distribution areas overlap. However, the plumage of the Bengal Huus is reddish and it has orange rather than yellow eyes. The Nepaluhu is significantly larger and noticeably spotted on the upper side of the body. His eyes are dark brown.
distribution
The distribution area of the Koromandeluhus is mainly the Indian subcontinent. It extends from Pakistan south of the Himalayas as well as the Indian Sind, Punjab and Uttar Pradesh in an easterly direction to Nepal and from there in a southerly direction to Brahmaputra , Manipur and Bangladesh. Coromandeluhus are not only common in the entire northern half of the Indian subcontinent. They also occur in western Burma and sporadically in southeast China. There are three bellows that have been collected on the Malay Peninsula. These are presumably non-brooding wanderers from the north.
habitat
The Koromandeluhu is widespread in regions with a dense population of forests and wetlands. In contrast, it is absent in arid regions and deserts. It occurs, among other things, in old mango plantations, groves, avenues with old tamarind stocks or other leafy trees. Proximity to the water is essential for him. Its height distribution extends up to 250 meters above sea level.
Way of life
The Koromandeluhu usually transmits in dense foliage and becomes active at dusk. Unlike many eagle owls, it also hunts relatively often during the day, especially on cloudy days or in light rain. It is very faithful to its location when it is not disturbed and couples often stay in the same territory for several years.
Its food spectrum includes small mammals, birds, reptiles, frogs, fish, and large insects. On the basis of stomach contents and food remains, rats, rabbits, squirrels, pigeons, parrots, coots , rackets , paddy herons and in particular glossy and thick-billed crows have been identified as part of its prey spectrum.
The breeding season falls from November to April. In northern India, the peak of the breeding season is December to January. It mainly breeds in the abandoned nests of other large bird species such as harriers, vultures or eagles. The clutch consists of two eggs that are laid with a large laying distance. This leads to a very large difference in development between the nestlings. As a rule, only the older and stronger of the nest siblings grows up.
