people with an interest in birds seem to form more than a
triangle. instead, add one more corner to this triangle to
make a square, and then add "aviculturists" on that corner.
these are the true "ugly step-sisters" in this geometric
relationship.

there are some people out there who can put one foot (or hand)
upon each one of those described corners without losing their
balance.
