Soul Taker Secrets – Angel Wings

The Council of Twelve series is a YA fantasy/paranormal romance series where we meet celestial beings. The first book in the series is ‘Soul Taker’, where we meet the Council of Twelve, the most powerful individuals in existence, and the protagonist, Katie, a Guardian Angel-to-be. In the ‘Soul Taker Secrets’ category, I reveal the one or other ‘inside’ knowledge about The Council of Twelve, their consorts, and in this case, a little of their physical secrets.

Wing feathers

The wing feathers specialized for flight are characterized by uniform windproof surfaces, or vanes, on either side of the central shaft that is created by an interlocking microstructure. Also called remiges, these feathers are asymmetric with a shorter, less flexible leading edge that prevents mid-air twisting.

Tail feathers

Most tail feathers, or rectrices, feature an interlocking microstructure similar to wing feathers. Arranged in a fan shape, these feathers support precision steering in flight. Typically, birds have six pairs of feathers on the tail, which display increasing levels of asymmetry toward the outer pairs. In some birds, tail feathers have evolved into showy ornaments that are useless in flight.

Contour feathers

Contour feathers are what you see covering the bird’s body and streamlining its shape. Arranged in an overlapping pattern like shingles, the waterproof tips are exposed to the elements, and the fluffy bases are tucked close to the body. Sometimes brilliantly colored or uniformly drab, contour feathers can also help the bird show off or stay camouflaged. Contour feathers on the wing, called coverts, shape it into an efficient airfoil by smoothing over the region where the flight feathers attached to the bone.

Semiplume

Mostly hidden beneath other feathers on the body, semiplumes have a developed central rachis but no hooks on the barbules, creating a fluffy insulating structure.

Down

Similar to semiplumes with an even looser branching structure but little or no central rachis, down feathers, are relatively short and positioned closest to the body where they trap body heat.

Filoplume

Short, simple feathers with few barbs, filoplumes function like mammal whiskers to sense the position of the contour feathers.

Bristle

Bristles are the simplest feathers, with a stiff rachis that usually lacks barb branches. Most commonly found on the head, bristles may protect the bird’s eyes and face.

Now that we learned about the different feathers in the wings let’s look at the different wing-shapes.

In this picture, we can see the wing shaping feathers and their functionality.


Now, bird and angel wings basically have the same biological structure with one main difference. Their mobility is far more extended to guarantee the optimal function since, of course, angels don’t have tail feathers to brake, steer, and keep the balance of the wing carrier. And of course, they are much more reliable, due to the weight they have to lift.
