The Pale-headed Brush-finch Atlapetes pallidiceps is an emberizine finch that is confined to south-central Ecuador and critically endangered owing to cowbird parasitism and habitat loss. We report a marked increase in numbers of brush-finches after seven years of cowbird control, confirming that brood parasitism had been an important limiting factor, and that shooting with firearms can be an effective method of controlling local cowbird parasitism.
