Sunbirds......

Here are some photographs of the most beautiful tiny Sunbirds which i took. When i clicked the picture of a Sunbird for the first time, i showed it to my mom saying "look mom... i captured a humming bird......!!" But later came to know that these were Sunbirds, but not Hummingbirds... With the help of my wildlife photographer friends, i came to know more about these Sunbirds. These were found to be very hyper active and unstable or stationary at a place. It was very difficult to capture these photographs without a tripod stand. They used to just disappear in a fraction of seconds.. So here i am sharing some information along with the photographs of these Sunbirds which i took. Hopefully you will enjoy reading through.....!!

The Purple Sunbird (Cinnyris asiaticus) is a small sunbird. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. They have a fast and direct flight and can take nectar by hovering like a hummingbird but often perch at the base of flowers. The males appear all black except in some lighting when the purple iridescence becomes visible. Females are olive above and yellowish below. They share many similarities with the New World ("Americas") hummingbirds, as they are also able to hover in front of flowers to retrieve nectar.

The Female Purple Sunbird is greenish-brown with a bright yellow underside, a dark brown tail, and white tips on the outer feathers. Purple Sunbirds are mostly resident (non-migratory) and are distributed from sub-Saharan tropical Africa, the eastern tip of the Arabian Peninsula through the Indian sub-continent and into Southeast Asia.

A vocal species, the male purple sunbird perches on the top branch of a tree and delivers repetitions of a sharp chirp, followed by a loud song. This species is known to defend its territory by singing and chasing intruders.

The purple sunbird is predominately a nectar-feeding bird, but raises its young on small invertebrates. This species is capable of hovering like a hummingbird for short periods of time to feed on nectar while in flight. Usually, however, it feeds from flowers while perched, and is even capable of hanging upside down to feed. The purple sunbird obtains the nectar by inserting its long tongue down into the base of a flower and retracting it back into the bill.

Purple Sunbirds mostly feed on nectar - occasionally hovering in front of the flowers like a hummingbird, but generally, they prefer to perch in front of them to retrieve the nectar. To varying degrees, they will also feed on small insects and spiders, particularly when raising young. Insects are usually captured in mid-air.

These birds are very vociferous and will call and will join to mob owls or other predators. The song is rapid rattle followed by ringing, metallic notes. Other call notes include a "chwit" or "chwing!" notes. The primary breeding season is before the Monsoons, April to June in northern India and January to June in Sri Lanka. While feeding they flick their wings. They rarely hover at flowers and usually perch to forage for nectar.

The breeding season of the purple sunbird varies across the Asian continent, generally coinciding with the months where flowers are most abundant. During these months, the female purple sunbird constructs a hanging oval or pear-shaped nest from a tree, roughly three meters from the ground. The nest is built using an array of materials including leaves, grasses, hair, twigs, and caterpillar droppings, all woven together with cobwebs, with a small entrance near the top.

They mostly live in plains, but may move up to 5,600 feet (~1,700 meters) in the Himalayas and up to 7,900 feet (~ 2,400 meters) in southern India. They inhabit thin forests, but are also found in gardens and even in dense urban areas, where they are usually observed near flowering shrubs and trees.

The adult breeding male has a plumage that may appear all black (particular in low light) or dark metallic blue or purplish-black - depending on the light conditions. The wings are dark brown. During courtship displays, breeding males will flash their yellow pectoral tufts ("arm pits"), which are otherwise hidden. They have bright blue shoulder patches and an iridescent maroon collar around the neck.

The male purple sunbird has two distinct types of plumage. The breeding male is characterized by the metallic bluish-black body, and the tuft of crimson and yellow feathers under each wing.

 Less than 10 cm long they have a down-curve bill with brush-tipped tubular tongues that aid in nectar feeding. The male is glossy metallic purplish black on the upper parts with the wings appearing dark brown. The breeding male has the underparts also of the same purplish black, but non-breeding males may show a central streak of black on yellow underparts.

They have Green Metallic head. And are seen in pairs or small groups and aggregations may be found in gardens with suitable flowers. They feed mainly on nectar but also take fruits and insects. Groups of as many as 40 to 50 individuals have sometimes been noted.

Females are olive brown above with yellowish underside. There is a pale supercilium beyond the eye. There is a darkish eye stripe. The throat and breast are yellow becoming pale towards the vent. The outer tail feathers are tipped in white both in the male and female.

 In the breeding plumage, the male can be confused with the syntopic Loten's Sunbird which has a long bill and distinctive broad maroon band on the breast. Breeding males will sometimes show their yellow pectoral tufts in displays.

There is a patch of bright blue on the shoulder of breeding males. The maroon shine on the feathers of the collar around the neck is visible mainly during the breeding seasons.

The eclipse (non-breeding) male has a pale olive brown or yellow-grey upper plumage, except for blackish wings and tail. The chest and abdomen are yellow with a blue central streak extending from the throat to the abdomen. Males in the eclipse plumage were formerly separated as species currucaria.

The non-breeding male purple sunbird has a much duller ‘eclipse’ plumage that resembles the female, with yellow underparts and a dark line of feathers running down the center of the throat and breast.

A closer look at the eclipse (non-breeding) male

Female Sunbirds are yellow-grey to olive brown above and yellowish below. The throat and chest are yellow turning paler towards the vent. She has a faint yellow supercilium (line above eye). Her black tail has a narrow white tip.

Purple Sunbirds usually breed before the onset of the Monsoon (rainy) season, which varies by region. In northern India, it is from April to June and in Sri Lanka from January to June. The male performs a courtship display, which involves raising his head, fanning his tail and fluttering with partly open wings to expose his pectoral tufts ("arm pits") while singing to the female.

The nest is constructed almost entirely by the female within a 5 - 10 day period. The pouch-shaped nest is made out of unwoven, thin strips of vegetation, lichens and bark, and held together with cobwebs. The entrance is on the side, often with an overhanging projection. The nest is typically suspended from a low branch, but at times are attached to man-made objects, such as wires. The inner cavity is expanded by the bird opening its wings and turning around inside.

Conservation: Various conservation measures which benefit the purple sunbird are in place in the Kangchenjunga Conservation Area, in the Himalayas. WWF has partnered with the local and indigenous communities to conserve biodiversity. The area is protected and corridors have been established allowing migration of species to other protected areas. The purple sunbird is similarly protected within the Mahananda Wildlife Sanctuary, also in the Himalayas

THE MOON

The Stunningly Beautiful Moon.......

When i used to see the moon i would always think how would it be to be there over the moon. Always wanted to have a closer look through telescope. But never got to view though....!!
Since my work schedule during the day time was getting more and more busy, i decided to take out my camera one night. Thought what to capture in the dark... Suddenly i noticed the beautiful moon shining bright in the dark.. Immediately got hold of a tripod and adjusted my camera lens, and tried to focus over the moon... I was really so much surprised!! It looked so beautiful through the lens, but capturing it was a difficult task. Had to do a lot of adjustments to capture the craters over the moon. Some how managed to capture it with the very limited camera equipments i had. But got amazing results. Below are some of the pictures i managed to capture. Hope you all like it...

Taken from Hyderabad on 06th May 2014 at 11:56pm.. (No modifications done in color composition, except the Image being cropped to 30% to have a better clarity)

The beautiful moon with Its craters visible.. Its really awesome to see it live while taking such a picture.. Taken from Hyderabad on 18th May 2014 at 11:36pm...

Captured from Hyderabad.... Must check this in full screen mode.. The craters look awesome.. This time got to capture a part of the big crater of the moon (seen at the top)

STRUGGLE FOR SURVIVAL.......

Here is a sequence of photographs which I took at Lalbagh, Bangalore. Have put some of the pictures together to depict the sequence of fight of the Fish for its life and the fight of the Cormorant for its food....!! 

Its all a part of Nature's play.. Survival of the fittest....!!


Pic 1: The Cormorant tries catches a fish

Pic 2: The Cormorant catches a fish firmly with its beak

Pic 3: The fish tries to escape by hitting its fins over the eyes of the Cormorant, as a result of which the cormorant releases the fish and thus the fish tries to escape.

Pic 4: The hard work of fish goes in vain and the Cormorant again catches the fish, it then tosses it up in the air so that it gets a good grip on the fish.
Pic 5: The hard work of fish goes in vain and the Cormorant again catches the fish, and tries to swallow it live.

Pic 6: Still the Fish doesn't give up the hope.. It again tries to escape from the mouth of the Cormorant and its seen jumping in the water back again.

Pic 7: The Cormorant doesn't give up too... It still tries to catch the jumping fish within a fraction of seconds and tries to catch it again.

Pic 8: The Cormorant gets good hold on the fish and punctures the head portion of the fish (near eyes) with its strong beak. Blood flowing out of the fish is seen in the photograph.

Pic 9: The Cormorant gets hold of the fish and positions itself to swallow it.

Pic 10: Finally Cormorant succeeds in killing the fish, and swallows it completely.

The Macro World......

Here are some of the images of Insects and the tiny surroundings which i look in a closer way. Hopefully you all like these close-up images i took...


A Macro Close-up of a part of Butterfly's wing.. Check out the tiny scales which are in thousands.... We often see the moths and butterflies colors.. But that's due to the tiny thousands of scales present all over... Captured using Nikon D5100 with 18-55mm lens reversed...... (Hand Held)


Here is a Macro photograph of a part of Butterfly's wing.. If you observe closely, you will find the tiny scales which make these beautiful colors.... We often see colorful moths and butterflies colors.. But we hardly notice how these actually seem...!! Captured using Nikon D5100 with 18-55mm lens reversed. (Hand Held)
A marco photograph of a tiny water droplet on the wing of a Butterfly... Extreme closeup pic taken with Nikon D5100 with 18-55mm lens reversed (hand held) 

A closer look at the skeleton of a Butterfly's wing.....!! The tiny bubble magnifies this image even more at the centre.. At the top middle the tiny scales which make the beautiful colourful wing are seen... Picture taken with Nikon D5100 with 18-55mm lens reversed....

The long-legged fly (Dolichopodidae), make up a large family of true flies with more than 7,000 described species in about 230 genera distributed worldwide. The genus Dolichopus is the most speciose, with some 600 species.  They are generally small flies with large, prominent eyes and a metallic cast to their appearance, though considerable variation is observed. Most have long legs, though some do not. The males often have enlarged genitalia which can be useful for species recognition. The adults are predatory on other small animals.

The long-legged fly (Dolichopodidae), are medium sized or minute flies (1mm - 9mm). The eyes are contiguous on the frons of males (except Diaphorus where they are close set). The mouthparts are short in most species and have a wide aperture as an adaptation for sucking small prey.

A House Fly... Closer look at the compound eyes.. A human's eye is attached to muscles that allow it to move, expanding the field of vision and making it possible for the eye to gather more information about its surroundings. Instead of moving their eyes, flies receive information from several different points simultaneously. A fly's eyes are immobile, but because of their spherical shape and protrusion from the fly's head they give the fly an almost 360-degree view of the world.
The common housefly (Musca domestica) look at the world in quite a different way than humans do. The structure and function of a fly's eye are completely different from ours, and so they see shapes, motion and colour differently. Flies are also able to see light in a way humans cannot. A fly's eyes are immobile, but because of their spherical shape and protrusion from the fly's head they give the fly an almost 360-degree view of the world. In a human eye, the pupil controls how much light comes into it, which is focused by the lens onto the retina. The retina then relays information to the brain via the optic nerve. Because fly eyes have no pupils they cannot control how much light enters the eye. With no control over how much light passes through the lens, the fly cannot focus the image it sees. Flies are also short-sighted -- a visible range of a few yards is considered good for an insect.
Like all insects, ants have six legs. Each leg has three joints. The ant has two eyes, each eye is made of many smaller eyes. They are called compound eyes. The abdomen of the ant contains two stomachs. One stomach holds the food for itself and second stomach is for food to be shared with other ants. Like all insects, the outside of their body is covered with a hard armour this is called the exoskeleton.

Awesome Sparkles... An image of the tiny fly focused fully. In the previous i have focused only at the eye creating a Bokeh Effect over its remaining body(Previous Picture). Captured using Nikon D5100 with 18-55mm lens reversed..

Look at those colors... Focused at the eye, the head looks so colourful with a bokeh created because of the colorful tiny hair.. Captured this very tiny fly (size of about 3mm only) at the Lalbagh Gardens, Bangalore. Captured using Nikon D5100 with 18-55mm Lens Reversed...

A Honey Bee caught at work.....!! Captured using Nikon D5100 with 18-55mm reverse macro..
