Buzzard is the main extension to vulture of practical interest, but more of a full 13-limit system in its own right. It ~~can be~~ described as 53 & 58. As one might expect, 111edo is a great tuning for it.

Buzzard is the main extension to vulture of practical interest, finding 7 at only 3 generators down so that the generator is interpreted as a sharp ~21/16, but is more of a full 13-limit system in its own right as will be explained. It is most naturally described as 53 & 58 (though [[48edo]] is an interesting higher-damage tuning of it for some purposes). As one might expect, 111edo is a great tuning for it.

Its S-expression-based comma list is {[[1728/1715|S6/S7]], [[5120/5103|S8/S9]]} which because of the equality [[36/35|S6]]] = [[64/63|S8]] * [[81/80|S9]] tells us that in any nontrivial tuning (any tuning that observes [[64/63|S8]] and [[81/80|S9]]) it naturally finds an interval between 6/5 and 7/6 which in the 7-limit is 32/27 and in the 13-limit is 13/11, then because [[1728/1715|S6/S7]] is tempered out, that is also split into two so that it also finds an interval between 7/6 and 8/7 which in the 7-limit is [[~]][[8/7]] times [[~]][[81/80]][[~]][64/63]] or [[~]][[7/6]] divided by [[~]][[81/80]][[~]][64/63]], and in the 13-limit is [[~]][15/13]], so that it's clear this system naturally wants to be extended to and interpreted in the full 13-limit.
