Greater sage-grouse (Centrocercus urophasianus) are experiencing elevated nest predation from common ravens (Corvus corax) across their range. Previous research indicates that manipulating raven breeding success by oiling raven eggs (preventing raven chicks from hatching) results in increased sage-grouse nest survival probabilities, but the effect of oiling raven eggs on sage-grouse population growth rates remains unclear. We addressed four questions regarding the effect of egg-oiling on overlapping sage-grouse populations. First, we experimentally showed that oil applied to eggs caused embryonic failure rather than the nest disturbances associated with flushing and spraying eggs with water. Second, we found that causing raven nests to fail by oiling eggs was associated with a decline of raven densities at treatment sites relative to control sites. Third, we confirmed previously published findings that oiling eggs was followed by an increase in sage-grouse nest survival probabilities. Finally, we tested whether oiling raven eggs led to population growth of overlapping sage-grouse populations at treatment sites using a Before-After-Control-Impact design. While questions regarding long term effects remain, wildlife managers can use egg-oiling to help manage overlapping populations of ravens and sage-grouse, and potentially other sensitive prey.
