Food, stress, and circulating testosterone: Cue integration by the testes, not the brain, in male zebra finches (Taeniopygia guttata).
TLDR
Fasting increased corticosterone and decreased testosterone in circulation, indicating that the testes can integrate and respond to cues of stress directly, and local inhibition of testosterone synthesis may allow for rapid and reversible changes in physiology and behavior when conditions are inappropriate for breeding.About:

Glucocorticoids and Reproduction: Traffic Control on the Road to Reproduction
TL;DR: Understanding how glucocorticoids regulate fertility and infertility may lead to novel approaches to the regulation of reproductive function.
Journal ArticleDOI
Molecular, cellular, morphological, physiological and behavioral aspects of gonadotropin-inhibitory hormone.
TL;DR: Gonadotropin-inhibitory hormone (GnIH) is a hypothalamic neuropeptide that was isolated from the brains of Japanese quail in 2000, which inhibited luteinizing hormone release from the anterior pituitary gland.

Does corticosterone regulate the onset of breeding in free-living birds?: The CORT-Flexibility Hypothesis and six potential mechanisms for priming corticosteroid function.
TL;DR: The CORT-Flexibility Hypothesis is grounded on a solid foundation of research showing seasonal variation in the physiological stress response and knowledge of physiological mechanisms modulating corticosteroid effects, and six possible corticosterone-driven mechanisms in pre-breeding birds that may delay breeding initiation are proposed.
Journal ArticleDOI
Endocrine and neuroendocrine regulation of fathering behavior in birds.
TL;DR: This review focuses on proximate mechanisms of paternal care in birds, and places an emphasis on specific hormones that vary predictably and/or unpredictably during the parental phase in both captive and wild birds.

Stress reactivity, condition, and foraging behavior in zebra finches: effects on boldness, exploration, and sociality
Ondi L. Crino,Ondi L. Crino,Katherine L. Buchanan,Larissa Trompf,Mark C. Mainwaring,Mark C. Mainwaring,Simon C. Griffith +6 more
TL;DR: The data show that the foraging decisions which individuals make represent not only a trade-off between food access and risk of exposure, but their underlying physiological response to stress, and suggest fundamental links between social networks and physiological parameters, which largely remain untested.

The unequal variance t-test is an underused alternative to Student's t-test and the Mann–Whitney U test
TL;DR: The aim in this forum article is to argue for the greater use of the last of these tests, the t-test for unequal variances, which is not commonly used.

Ecological bases of hormone-behavior interactions : the emergency life history stage

TL;DR: Field work reveals that changes in responsiveness to LPFs have ecological bases, such as reproductive state, body condition etc., that in turn indicate different hormonal control mechanisms in the HPA cascade.

Sheng Zhao,Russell D. Fernald +1 more
TL;DR: This algorithm provides an objective and noise-resistant method for quantification of qRT-PCR results that is independent of the specific equipment used to perform PCR reactions.

The Zebra Finch: A Synthesis of Field and Laboratory Studies
TL;DR: This treatise aims to clarify the role of language in the ecology of songbird populations and investigates its role in the selection and mate choice of birds.
