Birds of Similar Flock

Some birds like to live in groups with one another. This may be due to the similar food habits of some different birds. Other reasons may be similar nesting patterns. I have observed that in the river beds which is full of brownish sand and assorted sized pebbles birds like Paddy Field Pipits, Crested Larks and Ashy Crowned Sparrow Larks cohabit. One more reason seems to be that their colours match the sand of the bed creating a perfect camouflage.

One day we found together Ashy crowned Sparrow Larks , crested Larks and pipits forage together in the Ghaggar river bed perhaps they are terrestrial birds. I could take a photo of Juvenile Ashy Crowned Sparrow Lark ( in Front) and Paddyfield Pipit in the back in the Ghaggar River passing near Panchkula city of Haryana in India.

Hope and Anxiety

House Sparrow sized, Baya Weavers are master craftsmen. Their nests are the works of great ingenuity. The summer months transiting into monsoon rains witness the intense activity of nest building by these tireless birds.

It is the male Baya Weavers which are more beautiful as compared to their female counterparts, who construct the nest. The sole purpose of the nest building is to find a suitable partner and make preparations for next generations.

When the nest is in the half way stage, the males invite the females. They make noises and flap their wings whenever female Weavers fly near the tree, these male Weavers flap their wings sitting on their half done nests to attract their attention hoping that one of them may be kind enough to inspect the nest and build a bonding.

Defeated the Physical Disability

Here are some great players from cricketing world who did great despite their physical disabilities. They defeated their disabilities with determination. Cricketers who defeated their disabilities.

  1. Tony Grieg: Great all rounder was affected by epilepsy at the age of 12 due to an accidentally.
  2. Jonty Rhodes: From South Africa had a mild epilepsy as a kid.
  3. Shoaib Akhtar: Called the Rawalpindi Express, he was the fast bowler from Pakistan. He has Flat feet and hyperextension in joints causing swelling in knees.
  4. Mansoor Ali Khan Pataudi: Indian Captain lost his eye in a car accident at 20 years.
  5. Bhagwath Chandrasekhar: Chandrasekhar was a unorthodox leg spinner. Many batsman couldn’t understood his leg spinners. This typical action was developed due to a withered right arm which was caused by polio.
  6. Len Hutton: During World War Second he was injured and after operations had asymmetrical arms.
  7. Martin Guptill: Martin Guptill is an opening batsman from New Zealand. He lost three toes on his left foot in a accident at the age of 13 but he is playing despite this handicap for 11 years.

One Planet : Seven Worlds

Sir David Attenborough is an icon in the field of wildlife world. He has explored and brought his rendezvous with nature to common man through his extraordinary documentaries. Now he has brought this documentary “One Planet Seven Worlds” which will be on BBC Earth.

Our Earth has 70% water in the form of oceans and 30% landmass. In the beginning, whole landmass was one continuous mass. At that time, lot was happening inside the Earth. Lots of tectonic activity was occurring and lava as it was cooling down was also spewing out.

Tectonic plates were colliding and pushing against one another. Slowly the single landmass began breaking into fragments. Ultimately it broke into 7 stable land masses separated from each other by the water. These are the seven continents. Asia, Africa, Europe, South America, North America, Oceania and Antarctica.

Each continent has unique climate and geology which has given rise to stunning individual bio-diversities on each continent. That is why, Attenborough calls them Seven Worlds. The series will feature remarkable, new behaviour from different continents. From the extremely hot African plains to frozen waters of Antarctica.

He will also touch how we are now destroying the habitat of the wildlife. Due to this, some species are faced with extinction. Forests are being cut, extreme fishing and pollution is threatening our own and the wildlife existence.

Trailer of One Planet Seven Worlds

Introduction features a very soulful song “Out There” by Australian born singer Sia.

“I pray
Yeah, I’m hoping that if I pray
Maybe you’ll talk back
‘Cause I pray for some faith, some faith today

This walk feels longer in the dark tonight
No hand to hold, no hand in sight
I pour my heart out to the blackest sky
Oh, spirit, can you hear my soul’s cry?

Can you hear my call? Can I have a sign?
‘Cause I am losing hope
Yeah, on my darkest night

This walk feels longer in the dark tonight
No hand to hold, no hand in sight
I pour my heart out to the blackest sky
Oh, spirit, can you hear my soul’s cry?

No, I don’t wanna walk alone, I want to believe
‘Cause I am losing hope
As love will speak to me
Can you hear my call? Can I have a sign?
‘Cause I am losing hope
Yeah, on my darkest night

I got a feeling you’re out there
I got a feeling you’re out there”

Pink Grasshopper

There is a river near my home. It is a seasonal River and has a large dry bed which is full of pebbles and sand. Many birds which lay their eggs in the nest made on the soil. I generally go for a walk and to take pictures there. Today while I was walking along the pebbles, I noticed a pink coloured pebble.

Something else Was there. It was a pink Grasshopper which is very rare. Usually the Grasshoppers are green coloured to match with the grass background for camouflage which gives them safety against predators.

But this one was of Pink Colour. It was also trying to use camouflage by sitting in the pebbles especially pink ones. It is an unusual and little-understood genetic mutation caused by a recessive gene similar to that which affects albino animals. This mutation results in one of two things happening or even a combination of the two; a reduce or even absence of the normal pigment and/or the excessive production of other pigments, in this case red which results in pink morphs. Such a morph is exposed to predators and rarely achieve the adulthood.

Elements necessary for humans

At present there are 118 elements listed in the periodic table. Some of these elements are commonly found on the earth in the form of ores. Some are radioactive and have very short half lives. Many such elements have been synthesized in the laboratory and live for a very short time.

Human body like other things existing is made of compounds which are made from the elements. Out of these 118 only some elements are connected with the human body.

Although elements as such don’t make up the body it is the combined form that is molecules constitute the human body. But elemental composition is as follows by mass.

Oxygen: 65%

Carbon: 18%

Hydrogen: 10%

Nitrogen: 3%

Other elements: 4%

Other elements include Calcium, Potassium, Phosphorus, Sulphur, Sodium, Chlorine, Magnesium, Boron, Chromium, Cobalt, Copper,  Fluorine, Iodine, Iron, Manganese, Molybdenum, Selenium, Silicon, Tin, Vanadium and Zinc.

Although these elements are used in very minor amount, they are crucial to some body processes.

Elements can be divided into different groups according to the functions they perform.

Building Blocks

The main building blocks of the body are proteins which are synthesized from amino acids. For these elements used are Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus and Sulphur. DNA also contains these elements except Sulphur. DNA is the genetic code.

Enzymes

Enzymes are chemicals which are catalysts for carrying out chemical reactions like breakdown of sugars and other macro molecules. Such enzymes use some elements like Magnesium, Manganese, Copper, Zinc, Selenium and Molybdenum. Enzymes play role in respiration, digestion, metabolism and immune system.

Nerves and Control

Brain sends messages to different parts of the body and this is a two way communication. Electrical signals are carried through electrolytic solutions like brines. Sodium, Potassium and Calcium ions this play the role of transmitting the signals. Similarly Chloride ions regulate the water in and out of cells. Iodine is used to make hormones which regulate metabolism.

Bones and Teeth

Bones make the template on which our body is hoisted. Strong bones and teeth are essential for the healthy body.  Bones and Teeth are made of Calcium and phosphate. Phosphate contains Phosphorus and Oxygen. Manganese element makes more stronger and resistance to breaking.

Blood

Blood is the lifeline of the body. Blood carries oxygen to the cells and removes the carbon-dioxide gas which is the byproduct of combustion reaction. Oxygen is carried by blood due to the presence of iron which binds the Oxygen. Other elements which are constituents of blood are Carbon, Oxygen, Iron and Cobalt. Cobalt is essential to make red blood cells.

Respiration and Energy

Respiration is inhalation of Oxygen. Adinosine Triphosphate (ATP) is formed during respiration which is the compound used by body as energy. Main elements involved here are Carbon, Nitrogen, Phosphorus and Oxygen.
