Male Loten's Sunbird with spider in its mouth
I found this male Loten’s Sunbird in my garden the other day with spider in its mouth. The Loten’s Sunbird or Long-billed Sunbird, Cinnyris lotenius (formerly placed in the genus Nectarinia), is one of a group of very small Old World passerine birds which feed largely on nectar. Sunbirds will also take insects, especially when feeding young and Loten’s Sunbird is possibly more insectivorous than other sympatric species. Their flight is fast and direct on their short wings.

Male Loten's Sunbird
Long bill separates this from the sympatric Purple Sunbird. The wings are browner and the maroon breast band is visible on the male under good lighting. The call is distinctive and they are also very active often bobbing their head while foraging.
The song of the male is a long repeated wue-wue-wue… with the last notes accelerated. The males may sing from the tops of bare trees or telegraph wires. Loten’s Sunbird is a resident breeder that is locally common in forest and cultivation in India and Sri Lanka. Two eggs are laid in a suspended nest in a tree. The bag of webs, bark and caterpillar frass.
Loten’s Sunbirds are small, only 12-13 cm long. They have long down-curved bills and brush-tipped tubular tongues, both adaptations to their nectar feeding. The bill lengths vary across populations with long bills found on the east of Peninsular India and in Sri Lanka.
The adult male is mainly glossy purple with a grey-brown belly. It is similar to Purple Sunbird, but is larger, has a longer sickle-shaped bill, and a different belly colour.
The eclipse male has yellow-grey upperparts, darker than Purple Sunbird, and a yellow breast with a blue central streak extending to the belly. The existence of an eclipse plumage in the adult male has however been questioned. The female has yellow-grey upperparts and yellowish underparts, but lacks Purple’s faint supercilium. The call is a buzzy zwick zwick.
Found only in peninsular India and Sri Lanka. The main region is along the Western Ghats and into the southern peninsula. There are scattered records from central India and into the northern Eastern Ghats near Orissa. Race hindustanicus is found in India while the nominate race is found in Sri Lanka.

Female Oriental Garden Lizard
This Female Oriental Garden Lizard (Calotes versicolor) was photographed using Canon EF 400mm f/5.6 L USM & 24mm extension tube set.
It is an agamid lizard found widely distributed in Asia. It has also been introduced in many parts other parts of the world. It is an insectivore and the male gets a bright red throat in the breeding season leading to a incorrect name of Bloodsucker. These lizards can change their colours, quite rapidly, but not as rapidly as chameleons.
Oriental Garden Lizard also known as Changeable Lizards are usually a dull brown, grey or olive with speckles or bands, but can can be seen in other colours such as bright green. These colour changes may reflect their moods. During the breeding season, the male’s head and shoulders turns bright orange to crimson and his throat black. Males also turn red-headed after a successful battle with rivals. Thus their other gruesome name of “Bloodsucker Lizard”. But they don’t actually suck anybody’s blood! Both males and females have a crest from the head to nearly the tail, hence their other common name “Crested Tree Lizard”.
Changeable Lizards are related to iguanas (which are found only in the New World). Unlike other lizards, they do not drop their tails (autotomy), and their tails can be very long, stiff and pointy. Like other reptiles, they shed their skins. Like chameleons, Changeable Lizards can move each of their eyes in different directions.
Changeable Lizards eat mainly insects and small vertebrates, including rodents and other lizards. Although they have teeth, these are designed for gripping prey and not tearing it up. So prey is swallowed whole, after it is stunned by shaking it about. Sometimes, young inexperienced Changeable Lizards may choke on prey which are too large. They are commonly found among the undergrowth in open habitats including highly urban areas. The lizards were introduced to Singapore from Malaysia and Thailand in the 1980s.
Breeding: Males become highly territorial during breeding season. They discourage intruding males by brightening their red heads and doing “push-ups”. Each tries to attract a female by inflating his throat and drawing attention to his handsomely coloured head. About 10-20 eggs are laid, buried in moist soil. The eggs are long, spinde-shaped and covered with a leathery skin. They hatch in about 6-7 weeks. They are able to breed at about 1 year old.
Role in the habitat: Changeable Lizards control the population of their prey. In turn, they are food for predators higher up in the food chain.
Status and threats: The Changeable Lizard is relatively common and found in a wide range of habitats. They appear to adapt well to humans and are thus not endangered.

Canon announced that it will release a firmware update for the EOS 5D Mark II allowing users to manually control exposure when shooting video. The new firmware will be available for download from 2 June 2009 on Canon web site. Following the launch of the EOS 5D Mark II in September 2008, Canon’s Research and Development team has listened closely to customer feedback to develop additions to the camera’s movie recording functionality.
Allowing EOS 5D Mark II owners to achieve even more stunning video results with the camera, the firmware update will include the following manual controls when shooting video:
- Full aperture selection
- ISO speed: Auto, 100 – 6400 and H1
- Shutter speed: 1/30th – 1/4000th second
The EOS 5D Mark II integrates full HD movie capability into a high-end 21.1 Megapixel camera; opening a multitude of new possibilities for photojournalists and news photographers. Since its launch the camera has proved its appeal to professionals working in diverse fields, from studio and wedding to nature and travel. Now, following customer feedback, Canon has improved functionality for professional video users, further unleashing the potential of the EOS 5D Mark II for cinematographers and photographers alike.
Disappointing news is that there is no news about 24p option to record movie.
