There is this very weird species of bird that just can't get enough of delicious human flesh. But the bird has a problem - humans are big, smart, and social, so this little birdie has a unique skill: getting humans drugged up and brought into the forest. How the bird does it is the weird part: you see, these birds have a symbiotic relationship with fungus and they let it grow in their feathers and have the fungus release their psychedelic spores into the air so the human will breathe it in, and when in the human the spores trigger hallucinations. Then, according to vocalizations of the bird, the spores stimulate the reward center of the brain and lead the human into the bird groups where they tear the human's flesh off and eat most of it. They place more spores in the rest of the cadaver and let it grow into more fungus to use to hunt humans.
So my question is: which bird would be the best candidate for a creature like this? What they will need is the brains to give off complex noises to trigger the fungus and a desire for human flesh. Also what fungus would would fit these qualifications, or could develop to fit them?
