In theory, females that can afford to do so may increase their fitness by investing in offspring of the sex with the greater probability of attaining high reproductive success. This has been observed in a wide variety of mammalian, reptilian and avian species although the proximate mechanism remains a mystery. Using a captive population of peafowl, Pavo cristatus, we investigated the relation between maternal quality, offspring sex ratio and plasma concentrations of the reproductive hormones… Expand
Maternal Condition but Not Corticosterone Is Linked to Offspring Sex Ratio in a Passerine Bird
TLDR
Evidence is provided that maternal condition is linked to brood sex ratio manipulation in blue tits, however, maternal baseline CORT may not be the mechanistic link between the maternal condition and sex ratio adjustment. Expand
Change in Body Mass Can Overrule the Effects of Maternal Testosterone on Primary Offspring Sex Ratio of First Eggs in Homing Pigeons
TLDR
It is proposed that not only the absolute values but also the complex interactions between maternal hormones and body condition ultimately affect the mechanism of primary offspring sex manipulation. Expand
Experimental evidence that corticosterone affects offspring sex ratios in quail

TLDR
Levels of testosterone, 17β-oestradiol and corticosterone are manipulated in breeding female Japanese quail using Silastic implants and results suggest that cortic testosterone may be part of the sex-biasing process in birds. Expand
Androgen-dependent maternal effects on offspring fitness in zebra finches
TLDR
The benefits of biasing sex ratio towards males by increasing androgen level in the yolk may be limited due to negative effects on male offspring performance early in life. Expand
Acute corticosterone treatment prior to ovulation biases offspring sex ratios towards males in zebra finches Taeniopygia guttata
TLDR
The results suggest that offspring sex ratios may be influenced at the time of meiotic division by acute exposure to corticosterone and provides evidence for the timing of this effect. Expand
Female field voles with high testosterone and glucose levels produce male-biased litters
TLDR
It is found that females with high preconception serum testosterone and glucose levels produced a male-biased litter, whereas there was no association between maternal corticosterone level and litter sex ratio, and several physiological traits of the mother may simultaneously be related to offspring sex ratio in mammals. Expand
No evidence for sex-specific effects of the maternal social environment on offspring development in Japanese quail (Coturnix japonica).
TLDR
Counter to expectations, there are no effects of the maternal social environment on offspring sex ratio, sex-specific mortality, growth, circulating androgen or corticosterone levels; the social environment during reproduction does not necessarily modify sex allocation and offspring physiology, even if it causes differences in maternal physiology.

Maternal Testosterone and Offspring Sex-Ratio in Birds and Mammals: A Meta-Analysis
TLDR
The meta-analysis provides evidence for a general positive influence of maternal testosterone around conception on the proportion of sons across birds and mammals, although less confidently so for the latter. Expand
Endogenous Corticosterone Elevations Five Hours Prior to Ovulation do not Influence Offspring Sex Ratios in Zebra Finches
TLDR
Results suggest that physiological levels of endogenous corticosterone, both baseline and acutely elevated near the time of sex determination may not be involved in the adjustment of primary sex ratios in Zebra Finches. Expand
Determinants of within- and among-clutch variation in yolk corticosterone in the European starling
TLDR
The results indicate that variation in yolk corticosterone can originate from variation in both the mother's quality as well as the quality of her breeding environment, and has the potential to alter the competitive environment within a brood. Expand

Offspring sex ratios in tree swallows: females in better condition produce more sons
TLDR
In tree swallows, investment in sons has the potential for higher fitness returns than investment in daughters, assuming that sons in better condition have greater reproductive success. Expand
Experimentally increased testosterone affects social rank and primary sex ratio in the spotless starling
TLDR
The results suggest that added testosterone had a direct role on the acquisition and maintenance of high social rank in female spotless starlings before egg formation and the maintenance of sex ratio differences long after having being implanted. Expand
Diet, maternal condition, and offspring sex ratio in the zebra finch, Poephila guttata
TLDR
Results show that facultative sex ratio manipulation and sex–biased mortality can act together to produce extreme sex ratios in this vertebrate. Expand
Experimental demonstration that offspring sex ratio varies with maternal condition.
TLDR
Experimental evidence is provided of an adaptive, facultative adjustment of sex ratio in response to changes in maternal condition in wild birds, which is commonly tested in wild populations. Expand
Primary and secondary sex ratio manipulation by zebra finches
  • R. Kilner
  • Biology, Medicine

TLDR
It is suggested that zebra finches manipulate both their primary and secondary sex ratios in relation to food availability to invest adaptively in sons and daughters, and support Trivers & Willard's hypothesis of adaptive sexual investment. Expand
Environmental sex determination in a reptile varies seasonally and with yolk hormones
TLDR
The association of maternally derived yolk hormone levels with the offspring sex ratio is demonstrated and two new aspects of temperaturedependent sex determination (TSD) are described, i.e. seasonal variation in both thermal response and yolk steroid levels. Expand
Maternal investment during egg laying and offspring sex: an experimental study of zebra finches
TLDR
It is suggested that differential hatching success of the sexes and sex differences in mass at hatching may constitute important factors shaping brood sex ratios. Expand
Circulating levels of luteinizing hormone and steroid hormones in relation to social status in the cooperatively breeding white‐browed sparrow weaver, Plocepasser mahali
TLDR
Results obtained thus far indicate that the hormonal control of aggression in white-browed sparrow weavers is different from that predicted on north temperate species, and more investigations are needed to establish the hormonal basis of reproductive behaviour and cooperative breeding. Expand
Maternal testosterone in tree swallow eggs varies with female aggression
TLDR
In tree swallows, Tachycineta bicolor, it is found that yolk testosterone was correlated with the aggressive interactions of the female before and during egg laying and did not vary with laying order in tree swallow. Expand

TLDR
The results suggest that early exposure to maternal estrogens in ovo might be involved in establishing intraindividual variation in female-specific phenotypic traits, as has previously been demonstrated for androgens and male behavioral traits. Expand
