Common Sandpiper

This bird is found throughout the subcontinent near rivers, tanks and creeks. Generally, hunts alone and feeds on insects, molluscs, worms etc.
It's the second time I am posting a sandpiper; this photograph shows the bird in much more details. I also love the reflection of the bird on the water surface. Photographed it with the smallest aperture possible with my H-7 to get a good reflection.

Indian Pond Heron

This is the third time I am featuring an Indian Pond heron; mainly because this photograph is better and sharper than the previous ones.
Watching this bird hunt is a great lesson in stealth. The heron stands upright at the waters edge, waiting patiently for any kind of movement and when the time is right, it jabs its beak into the prey like a spear. Sometimes, it wades into the shallows, aided by its long legs, moving forward circumspectly, with neck craned and bill poised with readiness.
Photographed near Sultan battery in Mangalore.

Oriental Garden Lizard

The last time I posted a photograph of a lizard , the long tail was not visible; this one features this adorable reptile in totality.
Though these lizards can change their colours, they can't do it as rapidly as a chaemeleon. This lizard was comfortably sitting atop a lamp post.

Large Pied Wagtail

Like you rightly guessed, this family of birds gets its name 'Wagtail' because of the constant motion of its tail. The bird has a prominent white eyebrow and are generally found in pairs. The female is the one with duller brown colour. The bird has a pleasant singing note and is pretty comfortable with humans. This one came as close as two feet from me.

Ashy Prinia

This sparrow sized bird is generally found in areas with reeds bordering streams and moist grassland. As I was photographing these birds, I realised that they enjoy sitting on a thin reed and swinging about, just like how a kid plays on a swing. The reeds were barely strong enough to carry their weight.
The first photograph was taken in fading light and hence lack details, but posted it to highlight the colour of the bird's posterior.
The bird produces a peculiar 'kit-kit-kit' sound which sounds like electric sparks. The exact way in which it produces this sound is still not fully understood. The bird also builds beautiful nests either of stitched leaves like a tailor bird or of woven fibers, like a weaver bird.
Do let me know your views.

Indian Treepie

This is not a good photograph, but unfortunately was the only one that I could manage to capture of this Indian Treepie. Will try to get a better one in future. Though this bird is generally found in wooded country and scrub jungle, it frequents residential areas, just like this one which perched on a tree next to my house. It is the size of a cuckoo but has a longer tail. It is omnivorous like the crow and is a member of the mixed hunting associations of birds that move about in the forest.

Green Iguana

Iguana's are a family of large lizards with a spiny back, generally found in South America . The photograph is of a green Iguana; these reptiles are green during their younger days and lose colour as they grow older.
The spines on the back grow upto the tail and they use it as a defense mechanism by whipping the tail. The Iguana can make it's tail break off and grow a new one like many other lizards.
The loose skin that you see below the lower jaw is called a 'dewlap', it is similar to the loose skin on many other animals like Cow, Ox( Zebu) or dog (mastiff). It is of different use to different species from cooling, scaring predators to storing fat. For the iguana, it helps in regulating body temperature and also uses it for display during mating.
