Why these birds hide their sexual trysts

Arabian babblers do many activities as a group, but there’s one thing they do in secret. Besides humans, they’re one of the few known species to regularly conceal sexual activity. Arabian babblers are cooperative breeders. While typically, only the dominant male and female mate, other group members help care for chicks. They forage together, and they even have a group morning dance routine. But when it’s time to mate, they slip away from the group, either hidden behind shrubs, or far out of sight. In theory, if the birds don’t see each other doing the deed, it’s unlikely to lead to conflict.
