I have always read that the Birmingham bowline cannot be made in the bight, yet here one is,... sort of.
If you tie a "legitimate" Birmingham and compare the two side-by-side, you'll note that there is indeed a difference, but the result is essentially the same two-loop knot, with two advantages:
1. Obviously, it can be tied in the bight. :-)
2. The two loops are very easy to size properly when forming the knot.
Just as in the Birmingham bowline, the two loops formed are independent, after tightening.
An interesting thing to note is that the "rabbit" here is made from a bight, and that it "goes around the tree" in the manner of a Dutch bowline, so as to wind up with the tail falling between the two loops. (If you go around in the standard direction, the result actually resembles a "Dutch" version of the Birmingham!)
I hope somebody finds this knot useful.
