"You can know the names of a bird in all languages of the world,but when you are finished ,
You will know absolutely nothing whatever about the bird.....
So let`s look at the bird and see what it`s doing --that`s what counts.
I learned very early the difference between knowing the name of something and knowing something."


-Nobel Laureate Richard P Feynman(1918-1988)

Encroachment




Over the years as the number of humans on the planet grew, pressure on the land and the natural resourses grew and we began encroaching more and more on the forest land, mostly to cater to growing greed than needs of us .Now the situtaion has so worsened that the animals are forced to move out of their shrinking natural habitats and into the human settlements and plantations in search of food....Every other day we read stories of leopards mared in traps,elephants dead due to poisoning or munching on firecrackers or hit by speeding trains... Now who are the `Encrochers' we humans or the animals? The pictures are from the tea estates of Valparai,TN.
Think of the effect the pesticide laden foliage has on the breeding biology and genes of all these animals and smaller organisms.
Think how we are killing off the future- our own...
As some Red Indian chief said Earth is not inherited from our ancestors, but borrowed from our children...

Atlas moth


The Atlas moth (Attacus atlas) is a large moth found in the tropical and subtropical forests in Asia. Atlas moths are considered to be the largest moths in the world in terms of total wing surface area (upwards of c. 400 square cm or 65 square inches). Females are appreciably larger and heavier. Females are sexually passive, releasing powerful pheromones which males detect and home in on with the help of chemoreceptors located on their large feathery antennae. Males may thus be attracted from several kilometres downwind.

Once mated the female lays a number of spherical eggs 2.5 mm in diameter on the undersides of leaves. Dusty-green caterpillars hatch after about two weeks and feed voraciously on the foliage of certain citrus and other evergreen trees. The caterpillars are adorned with fleshy spines along their backs which are covered in a waxy white substance. After reaching a length of about 115 mm (4.5 inches), the caterpillars pupate within papery cocoon interwoven into desiccated leaves. The adult moths emerge after about four weeks.

This is a photograph of a male Atlas moth found in Kalady town on 15-10-10. In September 2009 also, there was a sighting of a male atlas moth from the nearby Onampilli.

TREE PIE

We used to feed the squirrels around our place. Bread is their favourite food. Feed them banana or nuts, they look at you with an expression, "what the heck Lady, we get it all the time from your orchard!". Guess like human beings, they are also getting addicted to junk food.
Recently, our guest list has stretched to include a couple of other species - a pair of Red whiskered Bulbul , a pair of Magpie Robins, a family of Treepies and mynas and few crows. Among them, the juvenile Treepies are my favourites. They are so friendly that if I'm late to feed them in the morning, they unabashedly make a racket with their loud "kekke kekke kekke".(By the way has anybody noticed one thing? Treepies do make this sound when they come across food.)Infact, one of them is a such a daredevil that he/she doesn't mind taking the bread pieces left on my window sil.:)
They don't mind fighting with the squirrels for their share of bread. It's quite a sight to see them trying to intimidate the squirrels by puffing up their feathers.
So anybody interested in befriending a treepie, try to lure them with bread.

Russell's Viper

Hai, all,
Chelamattom, Perumbavoor, 30-9-2010, 5pm
My neighbor caught a different kind of fish with his net - a lethal one. The plastic net he used to cover his well ensnared (accidentaly) a small sized Russell's Viper (Malayalam - Anali) and the poor creature died of injury, fatigue and starvation as the casualty was noticed only after some days. I myself have two previous experiences of snakes getting entangled in similar nets on their own.
