Spot them at altitudes ranging between 4,900 and 10,500 ft. Himalayan Woodpecker - Recognized by a constant knocking sound. Himalayan Monal spotted on the Deoriatal - Chandrashila trek. Saturday, FebruHIMALAYAN MONAL NATIONAL BIRD OF NEPAL HIMALAYAN MONAL NATIONAL BIRD OF NEPAL MONAL Himalayan Monal (male) by Aditya Chavan, also known as the Impeyan pheasant. The colour shift response of feathers was different in the case of alcohols and other water-based solutions, suggesting different swelling behaviour of keratin against different liquids the water-based solution had the more pronounced effect. The Himalayan Monal - Probably the most well-recognized bird due to its vibrant feathers, it’s found in elevations from 7,000 to 15,000 ft. The shift in colour was suggested to be due to the swelling of the keratin layer of barbules that absorbed liquids and as a result modified the refractive index and periodicity of the internal photonic structures. A quick reversible change in colours of these feathers was observed when they were soaked in water and other liquids, which reversed upon drying. The feathers exhibited interesting hydrophobic properties, with the dull-coloured proximal end showing lower hydrophobicity with a contact angle between 90° and 110° compared with the iridescent distal end of a feather exhibiting a contact angle between 115° and 120°, attributed to the change in the internal structure and/or density of the feathers. Sharp changes in the reflected brilliance were observed from the feathers upon changing the illumination conditions, such as horizontal and azimuthal angles. Here, we have studied the internal structure of its feathers from different parts of the bird's body and showed that its beautiful colours and iridescence are due to photonic structures present in the internal structure of the feathers. The bird possesses spectacular iridescent plumage with a range of different metallic colours. The Himalayan monal is a bird in the pheasant family, and it is the national bird of Nepal.
