Artist's Comments

Just thuoght that this might be of help to someone wanting to draw accurate wings.
Notice that the flight feathers are not symmetrical. I often see wings drawn with symmetrical flight feathers. A bird could not fly if the flight feathers were symetrical.

Birds' wings bend basically the same way our arms do. The allula is the bird's thumb and can be moved a tiny bit independantly of the rest of the wing.
The primary flight feathers are attached to the 'hand' (which consists of 2 fused fingers). The secondary flight feathers are attached to the ulna.
The flight feathers usually are numbered the way shown. I think most birds have 10 primary flight feathers, but the number of secondaries can vary a lot (long-winged birds like albatrosses have over 30 of them while parrots and songbirds mostly have 8-10, and hummingbirds have 6).

Very good diagram! its nice to see how the wings are really sopossed to look, i think its an awesome model. I wish we could have something like this posted at my work because a lot of people dont know much about bird wings.

Thanks for the great diagram and explanation! I can see myself referring back to this a lot in the future.

deffinately a big help!
so, just curiouse, can a bird not fly if the 10'th flight feather is the longest and the rest shorten from there? are the 10 and 9th always shorter than the 8th? im just not sure cause i haven't seen a sea-birds wing up close but i didn't think that was the case with every species. Im just not sure :/

:wow: Fascinating. The secondary flight feathers aren't what I thought they were. I thought the greater underwing coverts were the secondaries.

Thanks for the lesson!

love it! great resource. looks like my squiggy, except she's got her wings clipped... little trouble maker.

I don't know for sure - actually I don't know if there are any birds where the 10th flight feather is longest but I do know the 8th primary is not always the longest one.
In general, birds with long pointed wings can fly fast for long distances in open air and birds with short wings fly slower but are more maneuverable (for flying through trees, ect.).

Well you have my permission to print it out and use it if you want, though I don't know how well the lines and test will show up.
