Description
Dinosaur/bird wings are tricky for a lot of artists. I have wanted to put together a handy little graphic like this for a while. Hopefully this make sense to you guys.Brought to you by my PatreonΒ www.patreon.com/arvalis

And to be fair Velociraptor wings are pretty big, at least juveniles were flying around like in Deinonychus.

Perhaps even more important for a hunter is increased maneuverability, turning with aerodynamic force in addition to foot friction. Also would share the load between arms and legs, although my turning radius is entirely limited by friction rather than leg strength.
I'm also curious how wings affect running on flat ground. Most likely top speed would be reduced with wings out due to increased drag, but for distance running you may be able to go faster and longer due to increased efficiency, holding your body level while your feet push forward instead of bouncing up and down like normal. Depends on exactly how much drag it adds, and how grippy of a surface you're running on.

Thanks, even for an animator very helpful

I normally forget that the second and third finger are likely attached to one another closely through flesh and I always accidentally draw them separate even though I know that's not right >.> very helpful diagram!

I how viable would a feathered wing be if it was based on the wing ofΒ Anurognathus, albeit without aΒ pteroid and instead havingΒ an opposable thumb?
Like the wing would have four digits in addition to the thumb with wing-finger consisting of a shortΒ metacarpal like AnurognathusΒ and three phalanx bones somewhat resembling the metacarpal andΒ phalanges of a bird's hand and the wing musculature would as close to a bird's wing as possible.

I know some simplification is necessary for clarity in your diagram, but I still feel it's a good idea to point out that primaries and secondaries do interact with each other as the wing folds and not just overlap rigidly (see these pigeon wing specimens viewed from underneath for instance,Β File:Hemiphaga_novaeseelandiae_(AM_LB1510-11).jpg Β ,Β File:Hemiphaga_novaeseelandiae_(AM_LB13591-12).jpg Β ). It's something that in my discussions elsewhere I've noticed people have good amount of difficulty with, understandably so as it involves many moving parts.

Yeah, basically the fingertip and elbow feathers are rigidly bound to the bones, and all the ones inbetween move to fold/spread the fans, with the two feathers closest to the wrist joint moving the most. It does reach a point where they can't fold any further (all primary quills more or less parallel to the fingertip quill and all secondary quills more or less parallel to the elbow quill), after which the primary feather group does slide completely underneath the secondary feather group so the quills make a criss-cross pattern like in the picture. But at this half-spread position, the fans should be partially folded and not overlapping much yet.

I hope you don't mind but I'm going to use this as reference.

Yes, they couldn't fly.. so there is no reason why these knobs on their bones should be interpreted as "quill knobs".
Not even ratites or most other birds have quill knobs. (I have a longer comment down below where i explain the theme).

No, unfortunately they couldn't fly or even glide. They did, however, use them to 'steer' when running at high speeds.

Christ if it is, that would be so tedious

very interesting... seems like a very useful guide

I have a question regarding bird wings: where the secondary feathers end at the elbow, are there more feathers (tertiary?) connecting the wing to the body or do the wing feathers stop there?
I ask this because whenever I see a wing with its wings spread (whether from the front or back), there always seem to be more feathers there. Or am I crazy?

There indeed are tertiary feathers, but they are soft and not stiff like the flight feathers (primaries and secondaries) are. It's for the purpose of reducing air resistance during up flap when the bird is pulling its wings up; the soft tertiary feathers aid in maintaining lift on the underside but twist out of the way when the wing is being pulled upwards when it prepares for the next down flap.
You can see the tertiary feathers clearly separate from secondaries in this photo: thumbs.dreamstime.com/z/set-baβ¦
