Do you know wingspan ratios for a lot of types of birds or just the one? I wanna know the dove ratio or smth.
The Rock Dove, or common pigeon, has about a 2:1 ratio in terms of wingspan to height. With a body length of an average of 13’ and an average wingspan of 26’, this is one of the smaller ratios I have seen so far, which is funny because of their really fat bodies. It’s like the intro to the bee movie.
They have elliptical style wings, which are common for many birds of that size, and videos seem to show that their wings actually slap together when the bird raises them to flap. Ouch.
Some wing refs I really should finish so I have something to reference when describing them in writing lol
Their dad's getting one 'cause sometimes I write him with wings, sometimes I don't, but I need a solid red nonetheless lol
