BACKGROUND:The harpy eagle (Harpia harpyja) is the largest Neotropical bird of prey and is threatened by human persecution and habitat loss and fragmentation. Current conservation strategies include local education, captive rearing and reintroduction, and protection or creation of trans-national habitat blocks and corridors. Baseline genetic data p...

Oryx (2006), 40:4:411-418 Cambridge University Press Copyright © 2006 Fauna & Flora International doi:10.1017/S0030605306001360 Species reintroduction programmes, in prioritizing areas for reintroductions, have traditionally used tools that include measures of habitat suitability and evaluations of area requirements for viable populations. Here we...
California condors are one of the most endangered species native to the mainland United States and are subject of intense effort regarding captive breeding and reintroduction. We analyzed 20 years of California condor egg records from the wild and from three captive propagation facilities for fertility, hatchability, and chick survivability, along...
Eggs that are abnormally small are called runt eggs, and they occur in clutches across a wide variety of bird species. We surveyed waterfowl researchers to determine the natural frequency of occurrence of runt eggs in wild nesting ducks, geese, and swans. Of 551,632 eggs examined, 215 were runts, yielding a frequency of 0.039%. They occurred at abo...
The Large-footed Finch (Pezopetes capitalis) is a neo-tropical species whose natural history is poorly documented. It has a restricted range, breeding only in the dense undergrowth of forest clearings and borders at middle to upper elevations in the highlands of Costa Rica and northwestern Panama (Carriker 19 10, Skutch 1967. Wolf 1976. Wetmore et...
The mean eggshell thickness of 11 eggs of bald eagles (Haliaeetus leucocephalus) and 21 samples of eggshell fragments (n = 32) collected from 14 nests in Arizona during 1977 to 1985 was 0.539 mm, 8.8% thinner than the pre-1947 (pre-DDT) mean for eggs from southern California and Baja California, Mexico. Eleven eggs analyzed for contaminants contain...
A method using eggshell membranes to determine egg content levels of DDE and polychlorobiphenyls (PCBs), two of the most ubiquitous environmental contaminants, has been validated. A comparison was made between the residue levels determined from the egg contents of 40 Peregrine Falcon (Falco peregrinus) eggs and from hexanesoluble extracts of the dr...
The entire population of the California Condor (Gymnogyps californianus) probably contains fewer than 50 individuals (Wilbur 1976, 1978). Within its recorded history the species has shown a continual decline in numbers. During the past decade there has been an especially alarming decrease in condor recruitment. Be-tween 1968 and 1975 the entire pop...
