Flocking flamingos in groups of 50 or more may be one key to encouraging successful reproduction, according to a study published this month in Zoo Biology. Researchers used global data shared by zoos and aquariums to study reproductive success and factors such as climate, flock numbers, and an equal sex ratio in four species of flamingo in 540 ex situ populations worldwide. The zoos and aquariums curate data on groups of flamingos using the Zoological Information Management System (ZIMS) provided by the nonprofit Species360.
