The Regulation of Egg Temperatures and Attentiveness Patterns in the Dusky Flycatcher (Empidonax oberholseri)
TL;DR: In this paper, the authors describe a hypothermie temporaire de l'œuf couve, un manque de soins vis-a-vis de celui-ci and l'alimentation de la femelle qui couve par le mâle seraient des reactions adaptatives pouvant reduire le conflit entre soin parental and temps passe a l'approvisionnement, permettant ainsi aux oiseaux dont la couvaison est effectuee par un seul sexe de

Changes in plasma corticosterone and adrenocortical response to stress during the breeding cycle in high altitude flycatchers
TL;DR: Monitoring of Dusky Flycatchers suggested that variation in the length of the reproductive cycle and degree of parental investment may help to explain the level of adaptive modulation of the adrenal stress response in species that breed in unpredictable environments.

TL;DR: General issues regarding the effects of food on avian reproduction, with particular focus on wild taxa for which tracking changes in food availability is critical to reproductive success are discussed, including new data on several taxa of cardueline finches.

Physiological responses to photoperiod in three cardueline finch species.
TL;DR: Testing for photo-induction of reproductive development and photorefractoriness in males of three cardueline finch species indicates that the reproductive systems of all three species were stimulated by long days, but that the crossbills, which are temporal opportunists, either did not become absolutelyPhotorefractory, or developed refractoriness more slowly than did the other two species.

Interspecific Variation in Photo-Induced GnRH Plasticity among Nomadic Cardueline Finches
TL;DR: Patterns of decrease in GnRH immunoreactivity, gonadal regression and molt suggest that some form of refractoriness to photostimulation develops on constant long days, and relatively small differences in the response of the neuroendocrine system to stimulatory cues such as day length may lead to remarkably different capabilities for reproductive flexibility even within a closely related family of birds.
