Natural Born Hustlers: Sex, Lies & Dirty Tricks

Sex, Lies & Dirty Tricks explores sneaky mating techniques. For example, a lusty low-ranking male in a mob of red kangaroos considers possible plan A and plan B options when only the alpha male has the right to mate with the females in the group. A male marsh harrier’s solution to avoid conflict with a dominant resident male during breeding season is to grow feathers that make him look like female. He fools the resident male, but is able to woo a real female and settle down to raise a family. The final hour also exposes the dark ways brood parasites avoid parental duties, and how their chicks go even further to get the full attention of their foster parents. It’s a tough world out there, so it’s not surprising that crafty animals turn to disguise, illusion, duplicity and mimicry to beat the odds and live another day.
