Peacock

Those who have visited Arunachala have noticed the many Peacocks both at Ashrams and also found to be inhabiting Ramana Nagar. The term "peacock" is commonly used to refer to birds of both sexes. Technically, only males are peacocks. Females are peahens, and together, they are called peafowl. The Indian Peafowl is indigenous to the country and is designated the national bird of India.



The male (peacock) Indian Peafowl has iridescent blue-green or green coloured plumage. The so-called "tail" of the peacock, also termed the "train", is not the tail quill feathers but highly elongated upper tail coverts. The train feathers have a series of eyes that are best seen when the tail is fanned. Peafowl are best known for the male's extravagant tail, which it displays as part of courtship. Peacocks don't develop their long trains until they are 3 years old and they molt the train yearly.

Males possess metatarsal spurs or "thorns" used primarily during fights. Suitable males may gather harems of several females, each of which will lay three to five eggs. Wild peafowl often roost in forest trees and gather in groups called parties. The female (peahen) Indian Peafowl has a mixture of dull green, brown, and grey in her plumage. Although she lacks the long upper tail coverts of the male, she does have a crest. Females can also display their plumage to ward off danger to their young or other female competition. The average lifespan of these birds in the wild is 20 years. The male size: Body, 35 to 50 in (90 to 130 cm); Tail, 5 ft (1.5 m) and Weight: 8.75 to 13 lbs (4 to 6 kg).



Colour in nature occurs due to two basic processes: pigmentation and structural coloring. Pigment is a substance that, like a dye, gives colour to living and inanimate objects. Peacocks and other structurally coloured animals and things, such as rainbows, soap bubbles and the blue sky, instead get most of their colour from light reflection. In peacock feathers, colour is produced by the reflection of light with frequencies within the partial photonic band gap. If you change the view angle, the partial photonic band gap will shift to short wavelengths for oblique incidence.

During mating season the bird will often emit a very loud high pitched cry, "may-awe, may-awe, may-awe." Peafowl are omnivorous and eat plant parts, flower petals, seed heads, insects and other arthropods, reptiles, and amphibians. A peahen's clutch may range from 3—12 eggs, although 4—6 is average. The eggs are usually laid 2 days apart and in the later afternoon. Peafowl eggs take 28 days to hatch. The young are known as peachicks.



Peacock watching is highly entertaining, specially when Peacocks and Monkeys decide to ‘have a go,’ and in this respect recall a fascinating afternoon on a roof at Ramana Ashram watching squabbling peacocks and monkeys.
