Population Trajectory of Burrowing Owls (Athene cunicularia) in Eastern Washington
Anecdotal evidence suggests that burrowing owls have declined in Washington. The Washington Department of Fish and Wildlife is currently conducting a status review for burrowing owls which will help determine whether they should be listed as threatened or endangered in the state. To provide insights into the current status of burrowing owls (Athene cunicularia) , we analyzed data from the North...
متن کاملHabitat Patch Size and Local Distribution of Burrowing Owls (athene Cunicularia) in Argentina
– Habitat quality and landscape structure are key factors that determine the distributions of animals. The general characteristics of the habitat of Burrowing Owls (Athene cunicularia) have been well studied, but little is known about how landscape structure affects this species. Other studies have suggested that food resources for owls should be higher in small patches because of increased edg...
متن کاملNest-Site Characteristics of Burrowing Owls (<em>Athene Cunicularia</em>) in the Snake River Birds of Prey National Conservation Area, Idaho, and Application to Artificial Burrow Installation
—Burrowing Owl (Athene cunicularia) populations are declining in many portions of their range, and research and management efforts into stemming declines are underway. One tool with promise is the artificial burrow, which can supplement nesting opportunities and play a role in research, mitigation, translocation, and reintroduction studies. However, few studies directly assess important burrow ...
متن کاملVentilatory and metabolic responses of burrowing owls, Athene cunicularia, to moderate and extreme hypoxia: analysis of the hypoxic ventilatory threshold vs. hemoglobin oxygen affinity relationship in birds.
We measured ventilation, oxygen consumption and blood gases in burrowing owls (Athene cunicularia) breathing moderate and extreme hypoxic gas mixtures to determine their hypoxic ventilatory threshold (HVT) and to assess if they, like other birds and mammals, exhibit a relationship between HVT and hemoglobin O2 affinity (P(50)) of their blood. An earlier report of an attenuated ventilatory respo...
