DescriptionThe habitat needs of the ferruginous pygmy-owl (Glaucidium brasilianum) are poorly understood. In the tropics, this common bird of prey inhabits many distinct vegetation communities or environments (e.g., Monroe 1968, Meyer de Schauensee 1970, Stiles and Skutch 1989, Sick 1993). A resident of woodlands and open forests, it is also found in the open, perched on telephone lines or fence posts (Ridgely 1976). At the northern edge of its range, the ferruginous pygmy-owl has been recorded in riparian woodlands and thickets (Bendire 1888, Breninger 1898, Oberholser 1974), live oak (Quercus virginiana), mesquite (Prosopis glandulosa) forest (Wauer et al. 1993, Mays 1996, Proudfoot 1996), and Sonoran desertscrub (Monson and Phillips 1981, Millsap and Johnson 1988, Abbate et al. 1996). In this chapter, we describe some of the vegetation types associated with the ferruginous pygmy-owl, with an emphasis on those found to support the highest densities of the owl. We then explore key pygmy-owl habitat components suggested by descriptions of those plant communities.
