Why do birds stand on one leg ?

Have you ever seen birds standing on one leg. Of course yes. If you have not, well, time to look around you and see how beatiful and mysterious our nature is. Coming back to one leg striking pose, it vividly prompts us to compare them with Yoga poses (which most of us seldom do even in imagination).

Of course these avians looks perfectly balanced, serene and in tranquil state with an occasional professional glance, towards us. Their gaze seems to be speaking to us like "Can you do like this - stand on one leg for so much time". Jokes apart, lets get to the reason for this behaviour.

The reason for this adaptive pose is to regulate the heat loss of their bodies. Upper body is covered with feathers so its always warm from outside temperature variation. As their legs are bare, so they are prone to outside mercury changes and consequently, they become pretty cold. So, by bringing one leg up, the bird don't lose as much heat and they stay warm and comfortable for long.

TRP - What does it mean

We have all heard about TRP ratings of a program in news or papers or advertisements. Have you ever wondered what does it mean and how are the ratings calculated. Lets find out.

What exactly is TRP ?
TRP stands for Televison Rating Point is a tool to judge the viewership of any channel or programme for a period of 30 days. It gives an index of the choice of people and thus helps in recognizing the popularity quotient among different age groups.

How is it calculated ?
There are two methodologies used for TRP calculation :

A device called as People's Meter is attached to a TV set in a few thousand viewers houses across varied demographies. This device would store all relevant statistics about the viewership and sends the data to a central server periodically. After a month, an average is taken to judge the ratings score.

Another way of calculating the TRP is via picture monitoring technique where a specific signal is transmitted through satellite channels at particular intervals, which is then decoded at a central server station.

Who calculates TRP ?
In India it is calculated by INTAM (Indian Television Audience Measurement)
