Egg yolk androgen levels increase with breeding density in the European Starling, Sturnus vulgaris (2004, unknown): “Indeed, Whittingham & Schwabl (2002) have recently reported a positive correlation between the number of aggressive interactions that a female Tree Swallow engages in and the level of yolk testosterone in her eggs.”
Effects of elevated yolk testosterone levels on survival, growth and immunity of male and female yellow-legged gull chicks (2005, unknown): “maternal behaviour, maternal condition, paternal traits, sex of the embryo or the social environment experienced by females at the time of follicle maturation (e.g. Schwabl 1993, 1996a,b, 1997; Mazuc et al. 2003; Gil et al. 1999, 2004; Petrie et al. 2001; Reed and Vleck 2001; Groothuis and Schwabl 2”
Yolk testosterone organizes behavior and male plumage coloration in house sparrows (Passer domesticus) (2004, background): “In the American coot, Fulica americana, androgen contents were correlated with the number of pairs in a pond (Reed and Vleck 2001) and in tree swallows, Tichycineta bicolor, yolk testosterone increased with intrusion rates into the territory (Whittingham and Schwabl 2002).”
Chapter 7 Hormones in Avian Eggs: Physiology, Ecology and Behavior (2008, background): “A study showing a positive correlation between aggressive encounters and yolk androgen levels in tree swallows (Tachycineta bicolor) (Whittingham and Schwabl, 2002) suggested that females cannot wholly control what goes into their eggs.”
Yolk androgens and begging behaviour in black-headed gull chicks: an experimental field study (2003, background): “…plasma hormone levels in the female (Schwabl 1996a) and may vary adaptively with the species’ reproductive strategy and social requirements (Schwabl et al. 1997; Eising et al. 2001; Groothuis & Schwabl 2002; Müller et al. 2002; Whittingham & Schwabl 2002, but see also Sockman & Schwabl 2000).”
Maternal hormones as a tool to adjust offspring phenotype in avian species. (2005, result): “Furthermore, a suggestion for a weak opposite trend with age has been found in another study [94].”
survival with an asymmetrical brain: advantages and disadvantages of cerebral lateralization (2005, background): “Whittingham and Schwabl (2002) have shown that in tree swallows, Tachycineta bicolour, the level of testosterone deposited by the maternal bird in the egg depends on the number of aggressive interactions she experiences before or during egg laying.”
