The densities of Chatham Island Pipits (Anthus novaeseelandiae chathamensis) and Skylarks (Alauda arvensis) on the south coast of Chatham Island were estimated at 7 individuals km2 and 10 ind. km2, respectively. Foraging behaviours used by Pipit differed significantly between rough fenland, pasture and beaches. Foraging behaviours also differed significantly between Pipits and Skylark on pasture, and Pipits moved on average 10 times further per minute than Skylark. The make-up of Pipit foraging behaviour on fields and beaches on Chatham Island also differed significantly from those at Wellington, North Island, during autumn.
