"Of all the birds that have achieved mastery of the air in their individual ways none is so specialized as the European, or Common, swift Apus. It spends almost its entire life on the wing, flying continuously day and night for months or even years at a time. Unless forced down by accident or by bad weather and cold, it stops gluing only when it has found a place in which to nest..."
