Owls as biomonitors of environmental contamination
Abstract
Exposure and effects of environmental contaminants on owls has been largely understudied. Research primarily has focused on two species, the eastern screech owl (Otus asio) and barn owl (Tyto alba). Most of this work has been conducted with captive populations at the Patuxent Wildlife Research Center in Laurel, MD. In the wild, work has been, or is currently being, conducted with great-horned owls (Bubo virginianus) at a Superfund site in Colorado and in agricultural croplands in Iowa, and barn owls at a Superfund site in Texas and in metal-contaminated regions of the Netherlands. As higher order consumers, owls bioconcentrate many different environmental contaminants through their prey. Owls have proven to be sensitive to a wide variety of toxic compounds, including PCB`s, metals, and fluoride. Endpoints examined include reproductive effects, eggshell thickness, residue analyses, cholinesterase inhibition, and induction of liver MFO`s. Much more work remains to be done using owls as biomonitors of environmental contamination, particularly with captive populations, salvaged individuals, raptor rehabilitation center birds, and with wild populations in areas around hazardous waste sites, smelters, landfills, agricultural croplands, and other major sources of environmental contamination.
