I've been designing an an intelligent, bat-inspired avian race, and I've been struck with a question that I need answered.
Now, I want to have these bats to fulfill different types of ecological niches that are occupied by birds. Think akin to eagles, terns, ravens, maybe even flightless cassowary analogues. I've included a picture illustrating some of the different wing shapes birds have.
This means that these bats would be specialized for different kinds of flight, which may mean changing the wing shape.
From what I've seen, most bats have wing shapes that fall under the elliptical shape category. It's kind of hard to find resources on different bat wing shapes.
Now, when I was thinking about changing the shape of the bats wings, I just thought I could change around the length and layout of the fingers until it fit the wing shape I was looking for. I don't think it's that simple though. As you can see from this picture, the different types of bird flight also depend on the birds feathers.
The solution I was thinking was making the webbing not go all the way to the tip of the fingers, making a sort of scalloped edge to mimic the feathers seen in some birds. But I don't know if it would negatively affect their flying.
Thus, my question. Could you make bat wings that operate like the different types of bird wings?
