TL;DR: This study reveals that δD measurements of feathers from migratory birds in Europe may be used to track their origin and movements, and so provide a powerful investigative tool for avian migration research in Europe.

TL;DR: Because of the chick’s slow growth and reduced daily need for food, brooding in Red-footed Boobies may not require a marked increase in parental effort, and the rise in corticosterone levels is probably more a reflection of slight changes in foraging activity.

TL;DR: HL secretion showed a dampened pattern in the three species, particularly in tropicbirds, and prolactin secretion increased from the prelaying period until the incubation and brooding periods and declined thereafter in boobies but stayed relatively unchanged throughout the breeding cycle in Tropicbirds.

TL;DR: This paper used a stable hydrogen isotope (δ D) isoscape for Europe and δ D analysis of feathers from harvested woodpigeons Columba palumbus in France, the Iberian Peninsula, and Corsica to estimate their natal origins.

TL;DR: In emperor penguins, increased prolactin secretion appears to be triggered around the time of egg laying and continues, driven by an endogenous mechanism, through incubation and brooding until rearing is completed.
