Population trends and implications for monitoring cactus ferruginous pygmy owls in northern Mexico
Article Abstract:
Population trends and environmental factors was assessed and determined to explain variation in trends, and evaluate the statistical power of monitoring program for future monitoring efforts. It indicated that relative abundance of male pygmy owls declined more in areas where height of upland vegetation was shorter, relative abundance of saguaro cacti was lower, and the zone of riparian vegetation was narrower.

Comparison of habitat conditions for spotted owls in 14 demographic study areas to conditions on federal lands surrounding them
Article Abstract:
A study including 14 study areas covering much of owl's geographic range is stated to be representative of most populations of northern spotted owls on federal lands in United States. To evaluate the validity of the statement, habitat conditions in the demographic study areas were compared with conditions on federal lands in the physiographic province outside of the study area boundaries.

Estimating and dealing with detectability in occupancy surveys for forest owls and arboreal marsupials
Article Abstract:
The rate of false absences for two species of forest owl and four species of arboreal marsupial based on eight repeat visits to fifty survey locations in southeastern Australia are examined. The results suggest that temperature, rainfall and habitat quality influenced the detectability of most species.
