What is a secondary feather?
Secondaries are the inner wing feathers, attached to the ulna bone of the lower “arm”. The number of secondaries is highly variable, related to wing length (the Feather Atlas illustrates a maximum of 12 secondaries). Unlike primaries, secondaries typically have rounded or squared ends.
What are primary and secondary feathers in birds?
In most bird species, there are 10 primary feathers on each wing. If these flight feathers are damaged or lost, a bird cannot fly. Secondary feathers: These run along the ‘arm’ of the wing and sustain the bird in the air, giving it lift. The number of secondary feathers varies with different species.

- Contour Feathers. Contour feathers give shape and color to the bird.

Because primary feathers are essential for flight, these are the wing feathers that are often trimmed on pet birds to minimize their flight capability.
How many primary feathers do bald eagles have?
The Bald Eagle has 10 full-length primaries (numbered from proximal to distal, p1 to p10), 14 to 15 secondaries (numbered from distal to proximal, s1 to s14 or s15), three tertials (numbered from proximal to distal, t1–t3), and 12 rectrices (numbered from proximal to distal, r1–r6, on each side of the tail).
