The document discusses different types of Pitohui birds found in New Guinea, including the Hooded Pitohui, Variable Pitohui, Rusty Pitohui, Black Pitohui, Crested Pitohui, and White-bellied Pitohui. Four types of Pitohui birds, as well as two other bird species, are able to produce powerful toxins in their muscles and feathers. These toxins, which are less potent than some poisons found in other animals, help protect the birds and act as a defense mechanism.
