Abstract: Haemosporidian parasites infecting birds show distinct heterogeneity in their distribution among host species. However, despite numerous studies on the prevalence and ersity of parasite communities across species, very little is known on patterns of differences between them. Such data is lacking because up to date the majority of studies explored the patterns of variation in infections in different years, different time of s ling within a year or a breeding cycle, different study sites or was based on a small s le size, all of which may affect the estimates of prevalence and parasite ersity. Here, the prevalence, richness and ersity of haemosporidian parasites from the genera Plasmodium and Haemoproteus were studied in two closely related non-migratory hole-nesting passerines: Great Tits and Blue Tits. Birds were s led in sympatrically breeding populations during two seasons at the same stage of their breeding cycle – late nestling care. Great Tits were more prevalently infected with Plasmodium and Haemoproteus parasites (97·1 vs 71·2%), harboured a higher proportion of multiple infections (26·2 vs 3·2%) and had a more erse parasite community (11 vs 5 parasite lineages) than Blue Tits. Observed differences between two host species are discussed with reference to their breeding densities and immunological and behavioural characteristics.

Abstract: Microbiome constitutes an important axis of in idual variation that, together with genes and the environment, influences an in idual's physiology and fitness. Microbiomes are dependent not only on an in idual's body condition but also on external factors, such as diet or stress levels, and as such can be involved into feedbacks between the external ecological factors and internal physiology. In our study, we used a wild population of blue tits Cyanistes caeruleus to investigate the impact of external habitat composition on the microbiome of adult birds. We hypothesized that – through differences in plant composition, potentially affecting diet complexity – habitat type may impact the ersity and structure of the gut microbiome. Blue tits breeding in dense deciduous forests tended to have more erse microbiomes and be significantly different in terms of microbiome composition from birds breeding in open, sparsely forested hay meadows. Distinct study plots also tended to differ in a number of parameters describing microbiome ersity. We observed no microbiome differentiation according to in idual characteristics such as sex or age. The study emphasizes that external environment is one of the important modulators of microbiome ersity and calls for more such studies in wild animal populations.
