Abstract
The cactus ferruginous pygmy-owl (
Glaucidium brasilianum cactorum) is a small, cryptic owl that is often difficult to observe. Its natural history and conservation needs are poorly understood. Despite ongoing research in Texas and Arizona, the available information remains limited. In addition, factors influencing demographics (e.g., habitat configuration, causes of mortality and reproductive failure, and prey availability) may vary geographically, increasing the need for information from all parts of the range. Without a significant commitment to additional research, management and recovery strategies will be difficult to develop. This chapter first describes the taxonomy and distribution of the ferruginous pygmy-owl (
G. brasilianum). It then discusses the known ecology of cactorum.
