The purpose of this publication is to convey research findings to the Bureau of Land Management and other federal and state agencies to expand the current understanding of Cooper’s hawk (Accipiter cooperii) and long-eared owl (Asio otus) nesting density, nest occupancy, and productivity information in areas affected by oil and gas development. The Piceance Basin in northwestern Colorado was chosen as the study area because it has a high density of nesting Cooper’s hawk and oil and gas exploration, extraction, and production activities. Of the 304 nest structures visited during the 2011 breeding season, 34% were classified as occupied, and 65% were classified as unoccupied. Of the occupied nests in which the outcome of the nesting attempt (i.e., failed, successful, or unknown) was recorded, an observed success rate of 50% and a nest failure rate of 34% was recorded. Consequently, the outcome of the nesting attempt was not recorded at 16% of the monitored nests. When considering all 2011 Cooper’s hawk and long-eared owl nesting attempts, fledging rates were 1.3 (± 0.23) and 1.4 (± 0.36) fledglings produced per nesting attempt, respectively. The number of fledglings produced per nesting attempt among Cooper’s hawk and long-eared owl significantly declined from 2010 to 2011; however, there was no statistical difference among occupied Cooper’s hawk nests and long-eared owl nests when examining differences in fledging rates at successful nests only. When pooling occupancy data involving several other raptor species, nesting area reoccupancy during the 2011 breeding season was low, with only 29% of occupied areas in 2010 reoccupied in 2011; however, nesting area reoccupancy was high for Cooper’s hawk. The results provide additional support of the stochastic nature of nest occupancy and annual reproduction of Cooper’s hawk and long-eared owl in northwestern Colorado. To benefit management planning and conservation efforts, these findings suggest additional research is needed to assess the importance of habitat heterogeneity and the ability of Cooper’s hawk to maintain overall production of young at a relatively high rate at the site-specific scale, while overall production might be low at the landscape scale.
