Abstract Vertebrate eggs contain maternal steroid hormones in their yolks; and in avian species the concentration of these steroids vary within and among clutches. The organizational actions of these variable doses of maternal steroids in the avian egg, analogous to those regulating the development of sexually dimorphic traits, are little explored. In this study, we examined the organizational effects of yolk testosterone in the house sparrow, Passer domesticus, a sexually dichromatic passerine… 
Do different yolk androgens exert similar effects on the morphology or behaviour of Japanese quail hatchlings Coturnix japonica
TLDR
Yolk androgens should be viewed as integrated components of the complex yolk steroid environment in species where the amount of A4 in the yolk much exceeds that of the other androgens.
Yolk Androgens and Development in American Kestrel Nestlings
TLDR
Over two field seasons, control clutches and clutches given the largest dosage of androgens had the highest number of nestlings hatch and fledge and androgens may be linked to the environmental conditions.

Yolk testosterone, postnatal growth and song in male canaries
Embryonic exposure to maternal testosterone influences age-specific mortality patterns in a captive passerine bird
TLDR
It is reported that injections of a physiological dose of testosterone into yolks of freshly laid eggs of a small, seasonally breeding songbird, the house sparrow, increased survivorship in a semi-natural aviary environment.
Organizational effects of maternal testosterone on reproductive behavior of adult house sparrows
TLDR
Testosterone treatment in the egg increased the frequency of aggressive, dominance, and sexual behavior of 1‐year‐old, reproductively competent house sparrows, providing evidence that hormone‐mediated maternal effects are an epigenetic mechanism causing intra‐sexual variation in adult behavioral phenotype.

TLDR
These findings indicate that female songbirds can bestow upon their eggs a dose of hormone that modifies the behavior of offspring, suggesting that variable doses of these hormones might explain some of the individual variation in offspring behavior.
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.

We tested the hypothesis that mother birds counterbalance the negative effects of hatching asynchrony for later–hatched chicks by increasing the yolk androgen concentrations in consecutive eggs of
Testosterone and sexual signalling in male house sparrows (Passer domesticus)
TLDR
The result suggests that testosterone can be causally involved in the expression of a secondary sexual trait in house sparrows, at least in terms of its seasonal exposure.
Interfemale variation in egg yolk androgen allocation in the European starling: do high-quality females invest more?
TLDR
Examining interfemale variation in allocation of the androgenic steroids testosterone and androstenedione to eggs in a wild population of European starlings found that there was significant interf female variation in yolk androgen concentrations.
Yolk androgens reduce offspring survival
TLDR
Additional studies are necessary in order to determine whether the deposition of yolk androgens is an adaptive form of parental favouritism or an adverse by–product of endocrine processes during egg formation, despite its adaptive significance.
No evidence for differential maternal allocation to offspring in the house sparrow (Passer domesticus)
TLDR
No evidence was found that suggested differential maternal allocation in this population of house sparrows, which raises the question about the possible constraints or overriding factors operating on patterns of reproductive investment in this species.
Yolk androgens and begging behaviour in black-headed gull chicks: an experimental field study
TLDR
The enhancing effect of yolk androgens on growth in this species arises at least partly through androgen-mediated effects on the chicks’ behaviour, which is supported by the hypothesis that this within-clutch variation in maternal androgens mitigates the disadvantage of last-hatched chicks in sibling competition.

Determinants of within‐ and among‐clutch variation in levels of maternal hormones in Black‐Headed Gull eggs
TLDR
The level of yolk androgen reflects the hormonal condition of the female, that in turn is influenced by her characteristics such as her age and aggressiveness, and the level of social stimulation, which may facilitate growth and motor development of the chicks.
