This bug is currently "expected".
To give you a bit of background info: There is only one direction set for when a bird spawn. This is to the right. Birds can spawn in different corners. The rotation can be different from the direction the bird flies. It is only refreshed, once the birds go in a different direction.
As this is only a small issue and difficult to fix, it may take a while to fix it.
