The commonest species in our home gardens has from time immemorial built its nests on the walls of houses. House-holders often keep an empty pot with a hole at the botton hanging on a nail on the outer wall their houses. The nests are often built there by these birds generation after generation. Each new season the birds throw out the old nest and build a new one. The biggest predators who eat the young are the 'Coucal' and the 'Rat-snake'. The parents stand guard all the time taking turns at 'watch-keeping'. The slightest noise makes the chick to open their mouths wide and stretch their necks upwards to receive food from their parents. about 4 feet above the ground where the house-dogs patrolled these nests have been built in a safe place.
