Science: Wall Bird

The British Council (a cultural promotion center) vouched for the newlydiscovered nesting habits of an African Kenya bird: the palm swiftwhich builds its nest vertically instead of horizontally.

The palm swift glues the nest with saliva to the side of a palm frond;then glues the eggs to the nest. To hatch the eggs, the parent birds(taking turns) grip the back of the nest with their feet, nestlethemselves against the eggs. When the young hatch, their parents helpthem to hold their perilous perch until they are ready to fly.
