Nesting Behaviour of Birds: No Nest

The most simple form of nest is no nest at all.Many birds donot build any nest.They either lay eggs directly on the bare ground or rock surface. Some make simple scrap on the ground to lay eggs. It is observed that birds who leaves the nest soon after hatching, generally build this type of nest or more accurately they don't need complex nest at all.Nightjars lay their two eggs directly onto the ground.Birds like Plovers, Pratincoles, Lapwings, Little tern make simple scrap to lay eggs. As the eggs are on open surface they generally camoufladge with their surrounding and there by protected from predators. The picture above is a Little ringed Plover Nest with egg on open ground near a river bank.
