Explicit mother care of Surinam Toad
I have seen tribal women carry their children on their back in pouches of cloth. I was reminded of this when I was informed about a different kind of frog (toad) that carries its young ones on its back! It is the Surinam toad (Pipa pipa, Star-fingered toad). It is also remarkable that it carries young ones from their embryo stage itself!

Mind stirring Nightjar!
At dusk we see birds that fly fast to their nests. But there are certain birds that hunt only in night's darkness and sleep at daytime. One such bird is the Nightjar (Caprimulgus asiaticus, Goatsucker, Common Indian Nightjar, 'Pakki' in Tamil).

The munificent tree - Palmyrah Tree!
Each year in summer we expect the arrival of a delicacy in the market. It takes the heat off our head and cools down the whole body. In my childhood I had also relished on a sweet drink related to that delicacy. These two products are from our Palmyrah tree (Borassus flabellifer, Double palm, Lontar palm, 'Panai maram' in Tamil). The tree has multiple uses from making huts to making palm sugar and what else not? Its black fruits contain the soft, jelly-like delicacy (that I mentioned earlier here) called 'Nuongu' in Tamil (Ice-apple).

Flying dracula - the Mosquito!
Mosquitoes have been made villains to me. As young, I heard a musical ringing sound over my ear when I retired to bed. That sound quickly shifted to the other ear! It is produced by nobody but by our mighty mosquito flying around. Though its name in Tamil language, 'Kosu' is used also to mean an easier work or a small sized person, the mosquito still remains the strongest giving nuisance and causing diseases such as Dengue, Chikungunya and Malaria. In 2006, when there was Chikungunya epidemic in India, the electric mosquito killing bat (zapper) was introduced to us by the increased population of these mosquitoes.

Winter spit? Wonder Nymph!
As I rose one day early in a winter morning and walked through the meadow, I found the indecent behaviour of somebody spiting out on the grass. There was the spittle on the leaf blade of the grass clasping it around. I was irritated about it and walked carefully avoiding it. Later I wondered to know from an article in a daily that it is an act by an insect's nymph and not by a human!

Reproducing Larva - the Axolotl!
We usually see that from egg caterpillar comes out, butterfly grows out of it and fly away. But in a type of Salamander (an Amphibian) its growth into an adult is hindered and it is stopped in its larval stage itself. This larva starts also to reproduce! This animal is Axolotl (Ambystroma mexicana, Mole Salamander, 'Mexican walking fish,' 'Waterdog').

Tunneling bird, the Kingfisher!
If you go near a tree and a blue bird flies out with a high pitched sound startling you, it might be a Kingfisher. Here in urban South India we frequently spot this tree kingfisher, called as White-breasted Kingfisher (Halcyon fusca, 'Meenkotthi' in Tamil).

A wonder herb, called Banana!
I had wondered in my younger days that how banana leaves are seen coming out of wayside dunes. In closer view I found out that they grew out of corms that were disposed off from the nearby plantations. This Banana tree (Musa paradisiaca, Sweet banana, Dessert banana, 'Vazhlaippazhlam' in Tamil) yields the fruits that we, the humans, apes, elephants and many other animals relish on. It is not a tree but a herbaceous plant!

The courtship wonder in Dragonflies!
I had often seen Dragonflies fly low over ponds touching the water surface now and then with their ends. And I have also seen them flying in pairs one behind the other, and wondered about them. These are the reproductive displays by virtue of their nature. We shall see about this interesting displays here.
