I’ve said it before, but those emitters don’t really rely on particleIllusion. They’re special because they use complex animated image sequences for the particles. So what you’re really asking for is a bunch of new animated images, which we just don’t have the experience or time to create.
The reason there were horses, birds, and other animals in that library was that a particleIllusion user donated his time and effort to create them for the pI community.
It’s a simple matter to swap out an existing particle image for another one in an emitter, so if you can find other animated sequences of a bird flapping, you can take the existing bird flock emitter and change it to use the new image.
As much as I’d love to create a bunch of image sequences for this sort of thing, it’s just not my area of expertise. Also, the majority of particleIllusion users are not looking for more flocks of birds or herds of animals emitters.
