Landing is a wonderful sight ! Painted storks have long slender legs ! - the one on the picture appears to have even longer legs !! Most of the aeroplanes designed by humans need to land on smooth, standardized surfaces called runways. A bird, can use structures that vary widely in diameter and texture, from overhead lines to branches to statues. How they transition from the air to a perch is a Nature’s wonder.
தமிழ் இலக்கியம் மிக சிறப்பானது .. .. ஒருவர் தம் கருத்தை மற்றவருக்குத் தெரிவிக்க இடையே பிறிதொருவரை அனுப்புவதே தூதாகும். தூதினைப் புறத்தூது, அகத்தூது என இரண்டாகக் கூறுவார். தலைவன் தலைவியிடத்தே தூது அனுப்புதலும், தலைவி தலைவனிடத்தே தூது அனுப்புதலும் அகத்தூது !! அரசர்கள், பகைவரிடத்துத் தூது அனுப்புதலும், புலவர்கள் புரவலர்களிடத்துத் தூது அனுப்புவதும் புறத்தூது -இதுவோ தம் வறுமையை தம் மனைவிக்கு சொல்லிய தூது .. தூது செல்லும் பறவை 'நாரை" .
நாராய் நாராய் செங்கால் நாராய்; பழம்படு பனையின் கிழங்கு பிளந்தன்ன !
பவளக் கூர்வாய்ச் செங்கால் நாராய் ;
நீயுநின் மனைவியும் தென்றிசைக் குமரியாடி, வடதிசைக் கேகுவீ ராயின்
The painted stork (Mycteria leucocephala) is a large wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. The only sounds they produce are weak moans or bill clattering at the nest.
Landing is an aviation term that, for a bird, involves coming down on the ground for rest or looking for food. High on the sky flying the bird selects its ideal landing spot, then tucks its wings in and dives down with legs open. Birds skillfully use their wings and also their tails to reduce speed, and control their landing, enabling them to descend on a branch in such a way as barely to disturb it. This is quite an acrobatic feat when one considers the speed at which they approach the landing spot. Sometimes birds actually beat their wings opposite the direction of flight to slow themselves down quickly.
They open their wings, flap, make the increased surface area catch the wind - acting like a wind break. In landing, birds use their legs and feet both as air brakes and to grasp the perch or surface. Small birds often land by gauging a desired perch and then by flying at a speed approaching zero at or slightly above the area; the legs and feet then serve the simple function of grasping the perch. Obliged to land at high speeds, most large birds use a ballistic approach !
Here is a Stork pictured on air, preparing to land !
