Hand-rearing reduces fear of humans in European starlings, Sturnus vulgaris.
Pending changes in European legislation ban the use of wild-caught animals in research. This change is partly justified on the assumption that captive-breeding (or hand-rearing) increases welfare of captive animals because these practices result in ...

American crow Corvus brachyrhynchos is a common species throughout North America. Crows play a role in the ecology of multiple diseases and a single laboratory experiment has shown the potential for crows to pass infectious prions, such as those associated with chronic wasting disease (CWD), in their feces after being force‐fed with infected material ...

Effects of satellite transmitters on captive and wild mallards
Satellite telemetry has become a leading method for studying large‐scale movements and survival in birds, yet few have addressed potential effects of the larger and heavier tracking equipment on study subjects.

Development of a reliable PCR‐based protocol for molecular sexing of king vultures Sarcoramphus papa
The king vulture Sarcoramphus papa is a large Neotropical scavenger that lacks external sexual dimorphism, complicating demographic, ecological, and conservation studies. Reliable sex identification is therefore essential, particularly for wild and managed populations. In this study, we assessed and optimized a PCR‐based molecular sexing protocol for S.

Comparative mortality levels among selected species of captive animals [PDF]
We present life tables by single year of age and sex for groups of animals and for 42 individual mostly mammalian species. Data are derived from the International Species Information System. The survivorship of most of these species has never been mapped
