  1. Don't quite see the nature's reasoning here. Blood isn't very nutritious, the bat needs to drink a lot, and if it misses a meal it dies. Most vertebrates which feed on blood do so out of neccessity, like the vampire finch which only turns to blood when food is scarce, but it's not like there's a shortage of insects in South America, is it?
