On that Sunday I was strolling near Bondel trying to capture some birds.. It was raining heavily that day and I was unable to find mach except this bird who was searching for insects in a nearby puddle. After seeing me it went near a pile of Granite rocks nearby. This gave me a nice opportunity to shoot him in a nice evening light. Here are some of the shots which I took with Canon EF 300mm f/2.8L IS USM on Canon EOS 7D with Canon EF 1.4x II Extender. All shots were taken handheld at 1/500th of second with f/4.0 and ISO 200.

The White-browed Wagtail or Large Pied Wagtail (Motacilla maderaspatensis) is a medium-sized bird and is the largest member of the wagtail family. They are conspicuously patterned with black above and white below, a prominent white brow, shoulder stripe and outer tail feathers. They are common in small water bodies and have adapted to urban environments where they often nest on roof tops. The specific name is derived from the city of Madras which is now renamed as Chennai.

The White-browed Wagtail is the largest species of wagtail at 21 cm length. It is a slender bird, with the characteristic long, constantly wagging tail of its genus. It has black upperparts, head and breast, with a white supercilium and large white wingbar. Unlike White Wagtails it never has white on the forehead. The rest of the underparts are white. The female has the black less intense than in the male. Juveniles are like the females brown-grey where the adult is black.

The White-browed Wagtail is a resident breeder in India and is endemic to the Indian subcontinent. It is rare in the higher altitude regions but has been seen in Ladakh on the edge of the Tibetan plateau. In most of India it is found below 1000 m but in southern India it goes up into the hills up to 2200 m.

These wagtails have adapted well to urban habitats and is often found perched on overhead water storages in residential buildings. Usually seen in pairs or small groups near open water. They call often especially in the mornings and are active like most other wagtails. They will perch on the ground as well as on wires or on buildings. The song is long and loud with many different notes. The usual call is a wheezy “wheech”. They can fly fairly rapidly for long distances and they fly with a bounding (dipping and rising) flight pattern and have been recorded to travel at the speed of about 40 km/h.

Like other wagtails, this species is insectivorous. Nestlings were mainly fed orthopterans, caterpillars and spiders. Stayphylinid beetles and pentatomid bugs have also been recorded in their diet. Local name for wagtails in India is dhobin meaning washerwoman.

Coppersmith Barbet

June 18th, 2010
Coppersmith Barbet

Coppersmith Barbet

I had written earlier about Two Barbets. I had opportunity to follow same Coppersmith Barbet (Megalaima haemacephala) which was at that time building a nest. I was able to observe their nest at close quarter for over 1.5 months. I saw them raise their two chicks which finally flew off as healthy juveniles. I had use my Canon EF 300mm f/4.0 L IS USM with Canon EF 1.4x II Extender on Canon EOS 7D to take these series of photos as my 300mm f/2.8 was still not available.

The Coppersmith Barbet, Crimson-breasted Barbet or Coppersmith (Megalaima haemacephala), is a bird with crimson forehead and throat which is best known for its metronomic call that has been likened to a coppersmith striking metal with a hammer. It is a resident found in South Asia and parts of Southeast Asia. Like other barbets, they chisel out a hole inside a tree to build their nest. They are mainly fruit eating but will take sometimes insects, especially winged termites.

Emerging out of Nest

Emerging out of Nest

This bird belonged one of the nine sub species called Megalaima haemacephala indica (Latham, 1790) which is found in the Indian Subcontinent form northeastern Pakistan and extends into Sri Lanka and Vietnam.

This Coppersmith had built its nest in a small tree hole of a Mango Tree (Mangifera indica) Courtship involves singing, puffing of the throat, bobbing of the head, flicking of the tail, ritual feeding and allopreening. They breed through much of the year with local variation. The breeding season is mainly February to April in India. Both sexes excavate the nest on the underside of a narrow horizontal branch. They may also roost inside the nest holes. Three or four eggs are laid and like in many hole nesting birds the incubation period is not well known but has been estimated to be about 2 weeks. Both sexes incubate. Often two broods are raised in quick succession.

On a Branch

On a Branch

Throughout their wide range they are found in gardens, groves and sparse woodland. Habitats with trees having dead wood suitable for excavation is said to be important. Birds nest and roost in cavities. In the Himalayas it is found mainly in the valleys of the outer Himalayas up to 3000 feet. They are rare in the dry desert zones and the very wet forests.

Keeps solitary, pairs, or small groups; larger parties occasionally on abundantly fruiting Ficus trees. Fond of sunning themselves in the morning on bare top branches of tall trees, often flitting about to sit next to each other. The flight is straight, with rapid flaps.

Inspecting nest hole

They compete with other cavity nesting birds and frugivores. Megalaima asiatica have been noted to evict them from their nest holes, while Red-vented Bulbuls have been seen to indulge in kleptoparasitism, robbing the male of berries brought to the female at the nest. The nest holes are also used for roosting and some birds roost alone in cavities and these often roost during part of the day. Immatures will roost with the parents but often return to roost early so as not to be prevented by the parents from entering the roost cavity.

Fly away

Fly away

The call is a loud rather metallic tuk…tuk…tuk (or tunk), reminiscent of a copper sheet being beaten, giving the bird its name. Repeated monotonously for long periods, starting with a subdued tuk and building up to an even volume and tempo, the latter varying from 108 to 121 per minute and can continue with as many as 204 notes. They are silent and do not call in winter.

Fly away

Fly away

Prefers Banyan, Peepul, and other wild figs, various drupes and berries, and the occasional insect, caught in aerial sallies. Petals of flowers may also be included in their diet. They eat nearly 1.5 to nearly 3 times their body weight in berries each day.

Big Lens Small Review

June 10th, 2010
Canon EF 300mm f/2.8 L IS USM lens

Canon EF 300mm f/2.8 L IS USM lens

After returning from Lakshadweep I received my new Canon EF 300mm f/2.8 L IS USM which i had ordered almost 2 moths prior to my departure to Lakshadweep Islands. Here is my short review on that. I find Canon EF 300mm f/2.8 L IS USM lens is an ideal walkabout lens. Lens really isn’t too heavy (only 2.5Kg ;-) ) and when combined with a good neoprene strap, there is no hardship on a good hike/walk and the performance and potential rewards are well worth the effort. In reality, you really won’t be holding the camera up to the eye for prolonged lengths of time. I also purchased an Indian made Gimbal tripod head via eBay for mounting this lens which I will review later.

The lens arrived in the CS30028 case, looked a bit feminine if truth be told (reminds of a vanity/make-up case). Also supplied is the obligatory slip-on lens cover, the E-145 in this case. This is a non-elasticated cover but quite awkward to remove and put back. I have found a 120mm plastic can lid which fits perfectly as a lens cap. It is easier than slip-on lens cover. The Canon EF300mm f2.8 is also supplied with the ET-120 lens hood. The lens hood is pain to slip on and off but is a life saver for all the glares as well as in preventing damage to front of the lens.

As with other Canon IS lenses, there is a comprehensive control panel to the side of the lens body. Uppermost on the switch control panel of the Canon EF 300mm f/2.8 L IS USM lens is the focus limit control. 3 options here, the 2.5 metres – infinity (full) setting allows the lens to focus from minimum distance to infinity. Then the 2.5 metres – 6.4 metres and finally 6.4 metres to infinity. Basically, if you’re target is expected within a known distance from you, it speeds up autofocus if the lens isn’t hunting through it’s entire range to get a lock-on.

Next we have the AF/MF switch. Says it all really, though you can always operate the camera in manual focus even if it’s set to AF, being FTM (full time manual) design. Personally I would have prefered the option of totally disabling the focus ring, as it’s can shift if you’re working from something like a beanbag.

Next we have the IS switch, Image stabilization on or off. It has confusing 1 & 0 setting which originates from binary, I is on and 0 is off. IS is of older 2-3 stop range but is very useful. The drive is also queit as compared to my Canon EF 300mm f/4 L IS USM lens.

Underneath the IS switch is the Image stabilization mode switch. Mode 1 controls movement vertically and horizontally, mode 2 just counteracts vertical movement so as to allow you to pan along with a subject without the IS system trying to compensate.

Lastly in this panel is the focus preset functions. Basically, you can set a focus distance on the lens, press ‘set’ and you can recall this distance at any time via the twist ring (the ring with the serrated edge) just in front of the focus ring. It’s handy feature if you’re likely to be shooting at 2 vastly different distances. I would prefer it if focus recall was an option on the 4 focus lock buttons and in a really ideal world, a focus recall button would be situated far closer to the camera body, or indeed controlled via the camera itself. I need to find out how to use them effectively.

The tripod collar can be simply removed from the Canon EF 300mm f/2.8 L IS USM, and this is my choice for use as a walk around lens.
To be honest, I haven’t had this lens very long, so this is just a first impression after 2 weeks or so, of some pretty grim weather. My main use for this lens is with tele-converters, so most of my initial use has been with the Canon EFII 1.4x and EFII 2x tele-converters attached, and quite frankly we all know what these flagship Canon EF 300mm f/2.8 L IS USM lenses are capable of used bare.

With the Canon EFII 2x Tele-converter auto focus speed does drop slightly, it’s fast and reliable but not exceptional as it is with a 1.4x tele-converter. As the whole combination is giving f5.6, all focus points on the Canon DSLR are available. Stopping down to f8 does reap the rewards over having the aperture wide open.

Minimum focus distance of Canon EF 300mm f/2.8 L IS USM lens is a relatively long 8.2′ (2.5m) for a maximum magnification of .13x. An extension tube can resolve this issue, but more assembly is required and infinity focus is lost. Maximum magnification is extended to .18x and .25x with 12mm and 25mm extension tubes respectively. Extenders do not affect the MFD (Minimum Focus Distance) of the lens they are mounted behind, thus the MM (Maximum Magnification) of the lens is also multiplied.

Over all results are fantastic, The Canon EF 300mm f/2.8 L IS USM Lens is probably most-noted for being extremely sharp. Results at f/2.8 are very sharp from the center right into the full frame corners and only a very slight improvement is noticed when stopped down. This lens is very usable at f/2.8 (I primarily use this lens at f/2.8) – if the super-thin DOF (Depth of Field) is adequate of course.

I am still getting my biceps ready to use these beast of a lens so wait for more photos soon. As you can see the samples of the pictures below I am using this lens as both macro & tele lens shootings birds and butterflies together (not in the same frame though ;-) ). Below are few early samples of House sparrow(Passer domesticus), Ashy Prinia (Prinia socialis) and Plain Tiger butterfly(Danaus chrysippus).
