Breeding Birds Of Virginia, Bryan D. Watts
Breeding Birds Of Virginia, Bryan D. Watts
Virginia Journal of Science
Virginia supports a diverse community of breeding birds that has been the focus of investigation for more than 400 years. The avifauna reflects the latitudinal position of the state and the fact that the border extends from the Atlantic Ocean to the Appalachian Mountains. A total of 224 species have been recorded breeding in Virginia, 214 of which are extant. Twenty species have colonized the state since 1900 including 14 since 1950. Of all extant species, 102 (48%) are considered common at least somewhere in the state and 64 (30%) are rare to very rare. Diversity varies by physiographic region …

Gazetteer And Site-Based History Of The Ornithology Of Sabah. Malaysian Borneo, Frederick H. Sheldon
Occasional Papers of the Museum of Natural Science, Louisiana State University
The gazetteer lists sites in the state of Sabah, Malaysia, where birds have been collected, studied, or watched. Its purpose is to identify locations for research and birding in Sabah and to provide a brief scientific history of the more important sites. Each site description includes latitude, longitude, and general information on location. For many sites, elevation, habitat, scientific or birdwatching importance, historical notes, citations of key papers, specimen records, and records of certain species are also included.

Total Mercury Concentration In The Kidneys Of Birds From Poland, Ignacy Kitowski, Radoslaw Kowalski, Andrzej Komosa, Agnieszka Sujak
Turkish Journal of Zoology
A study was conducted on mercury renal concentration in 154 individuals of 28 species of birds with various habitat and trophic preferences. The highest geometric mean concentrations of Hg were found in large piscivorous birds such as Cormorant and Grey Heron. The maximum mercury levels were noted for individuals of White-tailed Eagle and Great Crested Grebe. Significant differences in renal mercury concentration between Sparrowhawk individuals were found in winter and in spring. Male Sparrowhawks generally accumulated rather more mercury in their kidneys than the females. Statistically significant differences in renal mercury concentration between males and females were also found for …
