Megjegyzések:	Feathers are dead integumentary structures that are prone to damage and thus showgradual degradation over the course of a year. This loss of quality might have negativefitness consequences. Feather-degrading bacteria are some of the most prevalent feather-degrading organisms, yet the relationship between feather-degrading bacteria load andflight feather quality has rarely been assessed. We studied this relationship in free-livingHouse Sparrows during breeding and non-breeding annual lifecycle stages. We also con-sidered the size of the uropygial gland, given the antimicrobial function of its secretions,and the effect of body condition. The number of feather holes was positively associatedwith feather-degrading bacteria load and was negatively related to uropygial gland sizeand body condition during the breeding season in both sexes. In the non-breeding seasonwe found the same relationships, but only in females. The degree of feather wear wasunrelated to any of the variables measured during the breeding season, whereas it wasnegatively associated with uropygial gland size and positively with feather-degrading bac-teria load in the non-breeding season, but only in females. Our results suggest thatfeather-degrading bacteria may induce the formation of feather holes, but play only aminor role in the abrasion of flight feathers.
