Miranda Krestovnikoff presents the Panamanian Montezuma oropendola. In a clearing in the humid rainforest in Panama a tall tree appears to be draped in hanging baskets. These are the nests of a New World blackbird, Montezuma oropendola. The male produces an ecstatic bubbling liquid call as he displays to females, reaching a crescendo whilst bowing downwards from his perch, spreading his wings and raising his tail. They weave long tubular basket-like nests from plant fibres, which they suspend in clusters from tall trees. Colonies can contain up to one hundred and seventy nests, but more usually number about thirty.
