Other mammals in the reserve include buffalo, baboon, Grant's gazelle, Kirk's dik-dik and klipspringer, the latter at the rocky slopes south and east of the lake.

Same as in all the Rift Valley lakes, birdlife is plentiful and diverse in Bogoria. The lake is regularly visited by thousands of greater and lesser flamingoes, which gather at the shore opposite to the hot springs. However, occasionally curiosity kills the flamingo as well, since some unaware specimens die victims of sulphur emanations and high temperatures. The reserve also hosts among others some vultures, bustards, larks and prey birds, worth to mention the fish eagles, which due to the lack of fish have learned to hover on flamingoes.

In the last years, deaths of lesser flamingoes have increased alarmingly, replicating the high mortality recorded in 1994-95, specially at Lake Nakuru. Apparently, the phenomenon is due to the poisoning of waters by heavy metals and toxins as a consequence of toxic algae overgrowth in the lake waters, which the flamingoes filter through their bills while feeding.
