Contributions of bird studies to biology.
Birds are widely distributed, highly diversified, and exhibit behavior and social organizations equal in complexity to mammals, yet they are generally more conspicuous and approachable in natural environments. These attributes make birds excellent subjects in many areas of biological research. The topics in which studies on birds have figured prominently include the mechanisms of species format...
متن کاملPulmonary function studies in bird breeder's lung.
Pulmonary function studies were performed at the time of diagnosis in 10 patients, aged between 11 and 51 years, with bird breeder's lung due to exposure of between 9 months and 42 years. The studies were repeated after a varying interval in nine of these patients, following removal from exposure. In initial tests, diffusing capacity was impaired in eight patients and the arterial oxygen tensio...
متن کاملReproductive costs in terrestrial male vertebrates: insights from bird studies.
Reproduction requires resources that cannot be allocated to other functions resulting in direct reproductive costs (i.e. trade-offs between current reproduction and subsequent survival/reproduction). In wild vertebrates, direct reproductive costs have been widely described in females, but their occurrence in males remains to be explored. To fill this gap, we gathered 53 studies on 48 species te...
متن کاملIntroduction: Contributions of bird studies to behavioral and neurobiological research.
B irds have fascinated naturalists and amateur bird-watchers alike for thousands of years with their remarkable abilities and behaviors (Konishi et al. 1989). These include migrating thousands of kilometers using only the earth's magnetic fi eld as their compass (Wiltschko and Wiltschko 2010); memorizing and performing complex songs after limited exposure (Hultsch and Todd 2008); and " caching ...
