The North Island saddleback (Philesturnus rufusater) is a formerly endangered forest bird which is endemic to the North Island of New Zealand. Both the South Island saddleback and this species were formerly considered conspecific. The North Island saddleback has benefited from multiple population reintroductions and is now resident on nine off-shore islands totalling approximately 7000 birds, from the original 500 birds found on Hen Island.
