Black Swift

• Its wintering destination was a mystery until 2012, when tiny geolocators revealed that the Californian populations fly to western Amazonia, more than seven thousand kilometres away.
• It nests on seeping ledges behind waterfalls and on sea cliffs, and lays a single egg per season: it is one of the slowest-breeding swifts.
• Its chick can survive several days without food by entering torpor, an adaptation needed when bad weather prevents the adults from catching insects on the wing.
