Know your coffee birds: Jacu
Jacus (guans) are birds that eat ripe coffee cherries.One might imagine this habit would draw the ire of coffee farmers. But at least one enterprising producer is using the philosophy, "If life gives you lemons, make lemonade." Or in this case, "If life gives you bird crap with coffee beans it it, make coffee."
