Happy Holidays

Hi All,

I just thought I'd wish all of you a Merry Christmas and a Happy New Year.

I'm away on holidays at the moment and will not be able to post any new images on the blog as I do not have access to Photoshop. However, expect a whole lot of new posts from mid January covering  Flycatchers, Drongos Indian Rollers and a whole lot more.

Cheers,
Dev

White-rumped Munia



The White-rumped Munia or White-rumped Mannikin (Lonchura striata), sometimes called Striated Finch in aviculture, is a small passerine bird from the family of waxbill "finches". More info inside.
The White-rumped Munia is about 10-11cm in length with a stubby grey bill and a long black pointed tail. Adult birds are brown above and on the breast and lighter below. Sexes are almost impossible to distinguish in all subspecies.

The bird is a resident breeder ranging from South Asia, to Southern China, East to Taiwan and South to Sumatra. It frequents open woodland, grassland and scrub and adapts well to agricultural land use. It is a gregarious bird which feeds mainly on seeds, moving through the undergrowth in groups. The nest is a large domed grass structure in a tree, bush or grass into which 3-8 white eggs are laid. It is a common and widespread species across a large range and is not considered a threatened species by the IUCN.

I photographed this bird in our garden. It was having a drink in the bird bath when I noticed it and luckily the camera, with the 100-400mm, was with me. I had to push the ISO to 1600 as it was late evening and the light wasn't good. The fact that the birdbath was in the shadow of a tree didn't help matters either. I'm pretty happy that I managed to capture a sharp image of the bird using a shutter of 1/40, handheld.

Red-rumped Parrot


The Red-rumped Parrot is a medium sized slender parrot found in the south-east of Australia. More images and info inside.

The adult male, shown above, is bright green with a blue green head, a red rump and yellow shoulders and belly. The female is a duller olive green with a green rump and faint yellow or light green scales on the belly. Young birds of both sexes are duller in colour. It is similar to the Mulga Parrot.

 


The Red-rumped Parrot is found in open grassland or lightly timbered plains, as well as along watercourses and in mallee farmlands with access to water. These Parrots feed in pairs or small flocks on the ground preferring to feed on seeds and leaves of grasses. They will also feed on fruits and flowers in trees. They can be seen feeding with other Parrots, including Eastern Rosellas and Galahs.

These birds mate for life. The female chooses and prepares the nesting site, usually a hollow in a eucalypt tree or, as shown above, in hollows found in wooden beams of buildings. Eggs are laid on a decayed wood bed and the female incubates the eggs while the male regularly feeds her. The young can be fed for a while after they fledge.

The images in this post were taken at one of our friends farms in the Northern Hunter region of New South Wales. The birds are not easy to approach and I had to use a car as a hide to capture the images above. I was pretty lucky with the light as it was an overcast day. The female was perched in the shade under a roof and, as a result, the highlights in the background were blown.

Scaly-breasted Munia


The Scaly-breasted Munia is a common bird found throughout Sri Lanka, ascending to the highlands where it may be seen in the same habitat as the endemic Black throated Munia. More info after the jump.

The Scaly-breasted Munia, also known as the Nutmeg Manikin or the Spice Finch, is a resident breeder in tropical southern Asia from India and Sri Lanka east to Indonesia and the Philippines. It has also been introduced to Puerto Rico where they are already widespread in lowland agricultural areas. It feeds on seeds and can been seen foraging on grasslands and crops and is therefore considered a pest.

A typical clutch consists of 4 - 10 eggs which are laid in an untidy and dome shaped nest. It will move into gardens to occupy suitable nesting habitats. They move around in restless flocks, seldom staying in one place for long. The sexes are similar, juveniles have light brown upper parts  and have uniform buff under parts.

I found a small flock of these birds near the Thalangama tank one morning. They were moving about in the undergrowth feeding on seeds in the grass when I came across them. They move around a lot and it took a bit of patience to capture the image above. The bird in the image perched on a stick and paused for a little while to look around before disappearing into the undergrowth. Fortunately there was enough time for me to lock focus and capture the image.

White-browed Bulbul


The white browed Bulbul is a shy member of the Bulbul family of passerine birds. It is a resident breeder in Sri Lanka and the coasts of peninsular India. More info after the jump.

The white-browed Bulbul is about 20cm in length with a long tail. The upper part of the bird is an olive gray while the under parts are whitish. This species of Bulbul is identified by the white supercilium, the white crescent below the eye and the dark eye stripe. It also has a yellow vent, which is not always seen. The sexes are similar in plumage. It feeds on fruits, nectar and insects. It builds a cup shaped nest in a tree and typically lays two eggs per clutch.

The bird is usually detected by its characteristic call, a "loud rattle of sweetish notes", which is a familiar sound in the dry zone forests of Sri Lanka.

This photograph was taken at the Thalangama tank. I was out looking for Kingfishers when I came around a bend in the road and found it perched on a branch about 6 feet off the ground. It was very close to where I was standing and surprisingly it did not fly off or hide. I took these images at a focal length of 400mm. The light wasn't the best so I had to crank up the ISO to 1600. I was using the 400D at the time and wasn't too happy about increasing the ISO that much. At least I got a half decent image though!

Superb Fairy-wren



The Superb Fairy-wren is the most widespread of the ten species of fairy-wren found in Australia. Their range extends along the south eastern coast of Australia from Brisbane to Adelaide. It was once an abundant species and was once common in urban areas. More images and info inside.

The Superb Fairy-wren males defend a territory of between 0.5 and 2 ha. They live in family groups with the young of the previous years remaining in their parents' territory and contributing to the care of the younger siblings. During the non-breeding period the males moult into brown plumage similar to the females except for the tail which remains blue. The males also have a black beak while females and juveniles have chestnut coloured beaks.



Fairy-wrens have been described as the "least faithful birds in the world" because DNA fingerprinting has revealed that more than three quarter of the young within a "family" group are sired by males form outside the group. Females prefer "high quality" males and therefore, 4% of the males in an area sire 50% of the offspring. The attribute of the male Superb Fairy-wrens most related to their attractiveness to females is the duration they hold their bright blue breeding plumage. Older males are more attractive than younger males. Some "top quality" males moult directly from breeding plumage to breeding plumage.



I spent a fair amount of time trying to photograph these birds. They move around a lot in the undergrowth and therefore it is pretty hard to actually lock focus on them. To get a crisp image of them a relatively fast shutter speed has to be used. I could have increased the ISO but I wanted to produce images which had minimal noise. I guess using a hide would have been an option but I never had a hide or a substitute for one available.


The last two images show the actual colour of the Superb Fairy-wrens breast. It is a very dark blue but is often mistaken for being black.

I will update this post with images of a female Superb fairy-wren when I actually capture one!

Green Skimmer



The Green Skimmer is a widespread dragonfly in Sri Lanka. It is frequently found hovering near ponds, water ways, paddy fields and streams. More info inside.

This image was taken at Arankelle near Kurunegala. We were travelling up to Dambulla at the time and had planned to stop at Arankelle for breakfast as we wanted to have a look at the ruins of the ancient monastery. As I approached one of the ponds in the complex I noticed that it was teeming with dragonflies. The majority of them were either Green Skimmers or Scarlet Baskers. I sat on the steps leading down into the pond and waited a couple of minutes until this Green Skimmer settled on one of the reeds in the water. Fortunately I had the 100-400mm lens on the camera and was able to capture the image above without having to move any closer. The light was fairly good and I was able to shoot at 1/1000th of a second.

I also noticed a pair of dragonflies in the wheel position in flight but was unable to capture an image of them. I managed to lock focus on them but they moved before I could release the shutter.

I'm still not very good at identifying dragonflies and had actually thought that this Green Skimmer was a Sri Lankan Forktail. Thankfully Amila was able to correct me.

Black-rumped Flameback

 A Black-rumped Flameback photographed in Colombo, Sri Lanka

More images of this woodpecker can be found at http://devwijewardane.blogspot.com/2010/05/black-rumped-flameback-part-2.html

Out of all the birds found in Sri Lanka, the Black-rumped Flameback is one of my favorites. It is also one of the most familiar birds found on the island. More details inside.

Click here to see techs.

The Black-rumped flameback (also known as the red backed woodpecker) is an unobtrusive bird which frequents residential areas. However, its call, which rises and then falls in pitch and accelerates, may give away its presence. The red back and the black and white head and neck are distinctive and can only be confused with the Greater Flameback. The Greater Flameback has an Ivory coloured beak and does not have the two white stripes around the eye. The Black-rumped Flameback has a black throat while the Greater Flameback's throat is white. The Black-rumped Flameback, like all other woodpeckers, has a stiff tail which it uses to support itself against tree trunks. It also has zygodactil feet with two toes pointed forward and two pointed backward. It is a large species measuring in at 26-29cm in length and uses its long tongue to feed on insects.

A pair of Black-rumped Flamebacks frequents our garden in the heart of Colombo. We've had regular visits from these birds for years. The image above was taken from a bed room window at home. I was able to spend around 40 minutes photographing these birds as they hopped along the branches foraging for food just 20 meters away from where I was.

Glassy Tiger


The Glassy Tiger is a common butterfly found at an altitude of up to 5000 feet, over most of the island. More info on the butterfly and the image inside.

Click here for techs.

With a wingspan of 65-80mm it is the slowest of the Danaids. It spends much of its time between 5 and 10 feet and rarely flies up into the canopy. It is the most shade loving of all the Danaids and is frequently seen nectaring on flowers in the undergrowth. It has a chemical defense that protects it against predators. When handled, it plays dead and emits a foul smelling substance. The sexes are similar.

The male has scent patches on the hind wing. The pouch shaped patch on vein 1 is larger than the pouch on vein 2. Both are more swollen and visible on the underside than on the upper side. The markings on the Glassy Tiger are uniformly grey. It is also the smallest butterfly in the group.

The Glassy Tiger is similar to the Blue Tiger, Dark Blue Tiger, Female Dark Wanderer and the Common Mime.

The fact that it is slow in flight probably helped me when it came to capturing the image above. I followed it as it settled on a number of different flowers until I finally got the shot I was after. I used the 100-400mm lens for this and therefore I didn't have to get too close to it. I came across this butterfly in the middle of the afternoon which is probably the worst time to photograph Butterflies. The best time to photograph them is early morning before they "warm up" in the sun and become more active. Make sure that your shadow does not fall on the subject when you approach it as that tends to disturb them.

I've got more shots of this butterfly at http://devwijewardane.blogspot.com/2010/04/glassy-tiger.html

Rose-ringed Parakeet



This is the most common Parakeet in the low-lands of Sri Lanka. It is one of the few birds which is not protected as it is considered an agricultural pest. More info and techs inside.

To see the techs for this shot, click here.

The Rose-ringed parakeet regularly visits gardens in urban areas, including gardens in the heart of Colombo, feeding on fruits and seeds. They feed and move around in small flocks which are often heard screeching in flight. They nest in tree burrows and compete for nest sites with Barbets. Only the males have a rose collar and their faces have a powder blue tinge.

A bird feeder which is regularly filled or some fruit trees and a little bit of luck is all that is required to attract the birds to your garden.. The Parakeets do not take flight as easily as some other birds and they can be photographed with ease using a 300mm lens. The image above was taken at 400mm but I am confident that, if required, I would have been able to move a lot closer.

Phalaenopsis



I finally got around to using my home made soft box when we bought a Phalaenopsis Orchid over the weekend. More details after the jump.

In order to make the soft box, I cut out three sides and the top of a cardboard box and covered two of the sides and the top with white tracing paper. The remaining side was left open to allow me to photograph through it. I then cut out the bottom of the box to allow me to place it over a subject, if necessary. To create a background I used a piece of black bristle board pasted on the remaining side of the box.

A single Canon 430EX speedlight was used to light the flowers from camera right. I'm not sure what the settings on the speedlight were but I think it was shot at 1/4 of a second and zoomed to 35mm. The left hand side of the flower was lit with the light reflecting off the white tracing paper on the left hand side of the box. The image was taken at 1/200th of a second at f\10.

Sydney Opera House


I had been meaning to capture this image of the Opera house for a couple of weeks but, due to bad weather, I did not get around to it until this evening. This image is a 6 image stitch, created using Hugin. More information on how I captured the images, after the jump.

I noticed the great light this evening, as I stepped out of work and decided to head down to Circular Quay to capture another image of the opera house. Thanks to daylight savings, I was able to get home, grab my gear and make it down to the opera house with about 20 minutes to spare before sunset. After scouting out a location to set up the tripod, I took a few test shots and waited around twenty minutes after sunset to capture the images.

I used a 50mm lens at f10 to ensure that the lamps and the opera house were in focus. The test shots, which I took earlier, gave me an indication of the required shutter speed. From memory, the shutter speed used to capture these images was 1.6 seconds or 2 seconds. I used auto-focus and locked focus on the centre of the Opera house, then moved into manual focus and did not change focus during the entire shoot. I also used a remote shutter release to minimise camera shake.

I then used Photoshop to process the RAW files and stitched them using Hugin.

Black-shouldered Kite



Images have to be viewed large.

Over the last two years I have visited several national parks in and around Sydney with the hope of capturing a decent image of this raptor. Needless to say, I have had very limited success. This weekend I finally managed to spend 45 minutes photographing these beautiful birds of prey. More photographs and info inside.


 

We spent the long weekend at a friend's farm in the northern Hunter region about 4 hours drive north west of Sydney. The area where the farm was located was quite hilly and the slopes were covered in rocky bush land. The valleys were divided into numerous paddocks which were used for grazing and to grow Lucerne. This was ideal habitat for Kites and other raptors as there was an abundance of prey.  I had noticed several Nankeen Kestrels on the drive in and couldn’t help but feel optimistic about finally getting a decent shot of a Black-shouldered Kite.

 

I made an early start on Sunday morning hoping to get an hour and a half of photography done before breakfast. While photographing Superb-fairy wrens (a future post) in a Lucerne field I noticed a white bird perched on a branch about 30 meters off the ground. Initially I thought it was a cockatoo but when I zoomed in on it I realised that it was a Black-shouldered Kite. I promptly forgot about the wrens and started taking shots of the Kite instead. Unfortunately the Kite was facing me and I was unable to get a decent side on shot of the Kites black and grey wings. However the bird was well lit as the sun was coming in over my right shoulder. Ten minutes after I started photographing the kite it was joined by a second Kite.

 

The two spent about half an hour on the branch and I was able to capture a number of images of the birds stretching and in flight. Finally, to top things off, the first bird changed positions and I was able to capture a number of images of the bird where its wings were clearly visible.











Unfortunately I was unable to photograph any Wedge-tailed eagles over the weekend. Maybe next time…

Taj Mahal Complex



This shot was taken fairly early in the morning before the majority of visitors had arrived. See it in colour here.

 I prefer the black and white version as I feel the rays of sun light and the misty haze are more pronounced.

This is a part of the wall which surrounds the Taj Mahal and the gardens around it. The wall is built out of red sand stone and encloses three sides of the Taj Mahal. The fourth side faces the river Yamuna and is left open. The wall is interspersed with small buildings and domed watch towers. The garden facing inner sides of the wall is fronted by columned arcades. This is a feature of hindu temples which was later incorporated into Mughal mosques.

Although the white domed mausoleum of Mumtaz Mahal is the most familiar component, the Taj Mahal consists of an integrated complex of structures. These structures included mosques, other mausoleums and guest houses.

The Taj Mahal was commissioned by Shah Jehan after the death of his third wife in 1631. Construction of the complex started in 1632. The mausoleum was complete in 1648 and the surrounding buildings and gardens were completed in 1653.

Unfortunately, due to air polution, the white marble, which was used to construct the main maausoleum, is getting discoloured.
