Bi-pond (or pond at pond) is a 16-bit still life made up of two ponds.
Occurrence
Bi-pond is the twenty-third most common still life in Achim Flammenkamp's census, being less common than big S but more common than trans-boat with tail.[1]
It is the 23rd most common still life on Adam P. Goucher's Catagolue, being less common than big S but more common than trans-boat with tail. It is the most common still life with 16 cells, being 7 times as common as beehive on dock.[2]
Below are two bi-pond-producing regions. The heptaplet on the left forms one bi-pond, while the nonaplet on the right forms two bi-ponds in an arrangement known as the land of lakes, one of the lesser familiar fours. In addition, the pattern on the right has a nine-cell sibling shown in the land of lakes article, and the two R-sequences or two fleet sequences can potentially form in other ways.

A 3-glider synthesis for the bi-pond was found in 2014.[4] There are multiple known alternate syntheses.[3]
The octohash database contains 6 one-glider seeds for the bi-pond. There are 21 other one-glider seeds in the octo3obj database.
