Abstract: Abstract The uropygial gland has been hypothesized to play a role in sexual signaling through a “make-up” function derived from the effects of secretions from the gland on the appearance of the plumage and bare… read more here.

Abstract: Quantifying an individual's state as a fitness proxy has proven challenging, but accumulating evidence suggests that telomere length and attrition may indicate individual somatic state and success at self‐maintenance, respectively. Sexual ornamentation is also thought… read more here.
