Birds have an amazing power to adjust themselves in various weather conditions. They have evolved it by their own effort. 'Osmoregulation' is one of those process through a bird can balance the osmotic pressure in their body fluid. This is a regular process for the birds who often visit or stay or live in coastal area and desert area. But its very rare behaviour for Oriental Pratincole who seldom visit those particular areas... I'll share my observations about their 'Salt secretion' behaviour as a part of 'Osmoregulation' soon in Natural history section. This is first time that 'salt secretion' behaviour has been photographed in wild for Oriental Pratincole from Indian subcontinent.
