I believe there is also a function along the lines of
 
c(not) = sin u
 
where u is the number of degrees of the observer from the bird relative to the far side of the tree.   This explains why birds that hang out on tree trunks such as treecreepers and woodpeckers spend a lot of time going slowly around the back of the tree but zip across the front of it at Warp factor 9!  A draft UC graph is attached.
