Chapter 6: Research needs for the conservation of the cactus ferruginous pygmy-owl in Arizona

Abstract

In this chapter, we describe research needs for the conservation of the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum) in Arizona. Estimates of population size, structure, and dynamics, as well as demographic data, are needed for the recovery team to formulate sound population objectives. Habitat loss due to residential development may represent the primary threat to the pygmy-owl, yet the impacts of other human activities and of disease or predation have not been evaluated. Studies of the cactus ferruginous pygmy-owl’s habitat requirements are essential to determine the importance of various vegetation types to the owl, protect critical habitat on federal lands, and develop guidelines for residential development. Using annual population surveys in conjunction with continued nest monitoring, habitat sampling, and telemetry will best address Arizona’s owl research needs. Habitat studies and population surveys in Sonora, Mexico may be necessary as well. The use of nest boxes in riparian areas, while presenting potential benefits for the management of the owl, may also address habitat research needs.
