NATURE

Bustards take venom to 'flirt' moreAre these animals becaming crazy?

Those birds, didn’t become crazy. It looks like something crazy, but it isn’t.

Bustards are large, strictly terrestrial birds. Males may reach 18 kg; females are half the size of the males.

Scientists already knew the large birds, which are native to parts of Europe and Asia, snack on toxic insects to clear their guts of certain intestinal parasites, including bacteria, nematodes, and tapeworms.

But the new research, published this week in PLOS ONE, shows that males eat substantially more venom than females, a strategy that makes them appear healthy—and thus sexier—during courtship rituals.

Females feel attraction to the males who are clean and healthy for mating.
