The effect of variation in dietary intake on maternal deposition of antioxidants in zebra finch eggs (2003, background): “Compared to the lesser black-backed gull Larus fuscus, zebra finches had similar concentrations of αtocopherol but lower concentrations of retinol in yolk (Royle et al. 2001).”
Maternal testosterone in tree swallow eggs varies with female aggression (2002, background): “…red-winged blackbirds, Agelaius phoeniceus (Lipar et al. 1999a), American kestrels, Falco sparverius (Sockman & Schwabl 2000), lesser blackbacked gulls, Larus fuscus (Royle et al. 2001), common terns, Sterna hirundo (French et al. 2001) and black-headed gulls, Larus ridibundus (Eising et al. 2001).”
Yolk androgens and begging behaviour in black-headed gull chicks: an experimental field study (2003, methodology): “…content, but also egg mass, protein, vitamin and water content vary with laying sequence (e.g. in common tern, Sterna hirundo: Heaney et al. 1998; lesser black-backed gull, Larus fuscus: Royle et al. 2001), we used only the first-laid eggs of a clutch (A eggs) to compose the experimental clutches.”
Maternal hormones as a tool to adjust offspring phenotype in avian species. (2005, background): “Starling [27,70] Maternal age [70] Black-headed gull [24,25,69,73] Hatching asynchrony [69] Black-backed gull [65,77]”
Chapter 7 Hormones in Avian Eggs: Physiology, Ecology and Behavior (2008, background): “The interpretation of this pattern could be that egg production constraints eggs that are laid late in the sequence to contain less basic resources, but that females increase T in these eggs to increase the competitiveness of nestlings in situations in which abundant food would not be a limit to chi”
Sex-specific patterns of yolk androgen allocation depend on maternal diet in the zebra finch (2005, background): “Females may lay eggs containing greater quantities of carotenoids (Blount et al., 2002; Royle et al., 2001), lipids (Nager et al.”
Effects of elevated yolk testosterone levels on survival, growth and immunity of male and female yellow-legged gull chicks (2005, unknown): “…variation showed that in several species where hatching is asynchronous, the concentration of yolk androgens increases with laying order (e.g. Schwabl 1993; Royle et al. 2001; Groothuis and Schwabl 2002; reviewed by Gil 2003; Groothuis et al. 2005a; but see Schwabl et al. 1997; Ellis et al. 2001).”
Determinants of within‐ and among‐clutch variation in levels of maternal hormones in Black‐Headed Gull eggs (2002, background): “(Royle et al. 2001) that antioxidant capacity may vary with laying order depending on food conditions, and”
