At first the ornithologists thought it was because other types of berries were poisonous to them, but after some testing it was determined that extracts of other juices did not affect what the birds ate.

Red for other birds. Red for hearts. Red for blood. No one had ever observed them eating live prey before. Feathers awash in blood, they turned on each other.
