Thunderbird is a methuselah that stabilizes after 243 generations. It was discovered by Hugh Thompson in 1971 during his investigation of six-bit patterns, and named due to later resemblance to the indian emblem.

Its stable pattern has 46 cells and consists of four blinkers, four beehives and two boats.

The thunderbird is very common in symmetrical soups, but unlike many other symmetrical patterns, it is much rarer in asymmetry.

The thunderbird can be hassled in two known oscillators: the p64 thunderbird hassler and a p190 shown below.
