The Rufous Treepie is an arboreal omnivore feeding almost completely in trees on fruits, seeds, invertebrates, small reptiles and the eggs and young of birds;  it has also been known to take flesh from recently killed carcasses. It is an agile forager, clinging and clambering through the branches and sometimes joining mixed hunting parties along with species such as drongos and babblers. It has been observed feeding on ecto-parasites of wild deer. 

প্ৰজনন
