Nest poaching in Neotropical parrots

Article Abstract:

The rates of mortality due to nest poaching in 23 studies of Neotropical parrot were studied how poaching rates vary with geographic region, presence of active protection programs, conservation status and economic value of a species, and passage of the U.S. Wild Bird Conservation Act. Results of the study reveals that poaching of parrot nestlings for economic gain is a widespread and biologically significant source of nest mortality in Neotropical parrots.

Quantity versus quality in California Condor reintroduction: Reply to Beres and Starfield

Article Abstract:

The re-establishment efforts of the California Condor by identifying and discussing both demographic and behavioral problems inhibiting success are discussed. It is observed that maximal double clutching significantly reduces the potential number of parent-reared offspring as blind pursuit of maximum captive propagation undermines progress towards creating self-sustaining and properly behaving populations.

Demography of the California condor: implications for reestablishment

Article Abstract:

During 1980s, the population of California Condors (Gymnogyps californianus) declined rapidly due to high mortality rates among adult and immature birds. The most prominent factor was lead poisoning resulting from ingestion of bullet fragments in carcasses.
