When you’re looking for a table in a crowded cafeteria, you probably give wide berth 1 to the family that sounds like it’s sharing a big dish of whooping 2 cough. Well, not if you’re a house finch 3, particularly a male. Because a study in the journal Biology Letters shows that male finches actually prefer feeding near males who are visibly ill.
Finches don’t get whooping cough. But they are susceptible 4 to infection with something called Mycoplasma gallisepticum, a bug 5 that leaves them lethargic 6 and sporting a bad case of conjunctivitis, otherwise known as pinkeye. The disease is quite contagious 7 and can be passed from one finch to another while dining beak 8-to-beak. All the more reason, you’d think, for healthy birds to avoid sitting next to someone with crusty red peepers. Yet male house finches, when given a choice, opt 9 to break breadcrumbs with males who are obviously under the weather.
Why risk catching 10 a nasty infection when all you really want to catch is a quick bite? Because males infected with Mycoplasma tend to be less aggressive. So eating with the infirm means you’re more likely to wind up with seed in your beak than a beak in your eye.
