However a few birds, with large wings, can have far more secondaries. The Andean condor, which has wings of up to 1.5 metre has 25 secondaries. The wandering albatross has 32 secondaries. Such large wings helps these birds remain aloft for long periods of time. The outermost flight feathers are called the primaries.
Birds can have nine to twelve primaries, but the most common number is ten.
