The uropygial gland function as a defence mechanism to avoid colonisation and maintenance of pathogenic microorganisms on feathers, and thus protect birds from infections and feather degradation [ 20212526 ].

Males with gynecomastia may appear anxious or stressed due to concerns about the possibility of having breast cancer. The age of effective homeothermy in enlarged broods might even have preceded that of reduced broods because of the favourable thermal environment in these nests and the increased thermal inertia provided by a large brood Hill and Beaver, Age of effective homeothermy in nestling tree swallows according to brood size.

Looks like I have another article to write. Ecology and Evolution Instead, it led to higher loads of both total and keratinolytic bacteria on feathers compared to controls.

People with kidney failure are often malnourished, which may contribute to gynecomastia development.

The onset and degree of endothermic heat production, and hence the capacity for homeothermy, also vary with factors such as the length of the nestling period Dawson and Evans, ; Dunn,nest type and nest location Morton and Carey,and stage-specific predation risk Cheng and Martin, Mild cases of gynecomastia in adolescence may be treated with advice on lifestyle habits such as proper diet and exercise with reassurance.
