Garden Bird Feeding: Insights and Prospects from a North-South Comparison of This Global Urban Phenomenon (2017, background): “However, it is not a panacea and in the case of kakapo, as well as promoting recruitment, food supplementation resulted in unpredicted adverse effects such as breeding adult obesity (Powlesland and Lloyd, 1994) and an unwanted skew toward a male-biased sex ratio in offspring ( Clout et al., 2002).”
New Zealand island restoration: seabirds, predators, and the importance of history (2010, background): “Furthermore, comparative analyses showed that those females that had eaten supplementary food produced an excess of male offspring, an outcome predicted by sex allocation and parental investment theory (Clout et al. 2002).”
Predation and other factors currently limiting New Zealand forest birds. (2010, unknown): “…Sagar & Scofield 2006; supplementary feeding promotes more male kakapo chicks, Clout et al. 2002), predator control has routinely restored gender ratios in experimental studies published so far (Innes et al. 1999; Moorhouse et…”
Psittacine reintroductions: Common denominators of success (2012, background): “…kaka promoted site fidelity and facilitated post-release monitoring (Adams, 2005), and has improved survival and breeding success of reintroduced kakapo during short-term natural food scarcities (Elliot et al., 2006; but see Elliot et al. (2001) and Clout et al. (2002) for some caveats).”
A parrot apart: the natural history of the kakapo (Strigops habroptilus), and the context of its conservation management (2006, unknown): “This was followed by the finding that the sex of offspring can be influenced by the level of nutrition of the female (Clout et al. 2002); females whose body weights are high at the onset of breeding produce significantly more male than female offspring.”
PCR-based sexing in conservation biology: Wrong answers from an accurate methodology? (2006, background): “In conservation, endangered species management often places strong emphasis on an individual’s sex (e.g., Clout et al. 2002; Sutherland 2002; Groombridge et al. 2004), but as previously noted endangered species may contain few known-sex individuals with which to test the accuracy of a sex test…”
