When we think of parasites we're more likely to think of a mosquito or a leech, some gross bug that latches onto you and sucks your blood. We wouldn't normally think of a bird, but there are many freeloading birds out there, more than willing to take advantage of another animal. There are even some birds that suck blood. Today we're going to a rarely visited corner of the avian world to find vampires, pirates and changelings. It's going to be fun.To support Bird of the Week and gain access to our second podcast, What's up with that's Bird's Name? click on through to Patreon: www.patreon.com/birdoftheweekWant birds in your inbox?
