Reproduction in eastern screech-owls fed selenium Reproduction in eastern screech-owls fed selenium
Raptors are occasionally exposed to excessive selenium from contaminated prey, but the effects of this exposure on reproduction are unknown. Therefore, we fed captive eastern screech-owls (Otus asio) diets containing 0, 4.4, or 13.2 ppm (wet wt) added selenium in the form of seleno-DL-methionine. Adult mass at sacrifice and reproductive success of birds receiving 13.2 ppm selenium were...

Limitations of captive breeding in endangered species recovery Limitations of captive breeding in endangered species recovery
The use of captive breeding in species recovery has grown enormously in recent years, but without a concurrent growth in appreciation of its limitations. Problems with (1) establishing self-sufficient captive populations, (2) poor success in reintroductions, (3) high costs, (4) domestication, (5) preemption of other recovery techniques, (6) disease outbreaks, and (7) maintaining...

Mercury poisoning in wildlife Mercury poisoning in wildlife
Mercury is an intriguing contaminant because it has complex chemical properties, a wide range of harmful effects, and an infinite persistence in the environment. Die-offs of wildlife due to mercury have occurred in many countries, especially before mercury seed dressings were banned. Today, most mercury problems are associated with aquatic environments. Methylmercury, the most toxic...

Atlas of the Breeding Birds of Maryland and the District of Columbia Atlas of the Breeding Birds of Maryland and the District of Columbia
This was the result of a 5-year cooperative study with the Maryland Ornithological Society and the Maryland Department of Natural Resources. Each of Maryland's 1,256 5-km (25 sq km) blocks was surveyed for breeding birds using the standard categories of Possible, Probable, and Confirmed breeding. Special features include: (1) coverage of all blocks instead of a random sample; (2) one...
