“…These gut bacteria likely result from faecal contamination, either directly or via the egg passage through the cloaca. Two of the three Enterococcus OTUs found here -E. gallinarum and E. faecalis -have been associated previously with Pied Flycatchers (Moreno et al 2003;Ruiz-de-Castañeda et al 2011a). …”

“…To date, most avian nest microbial studies have focused on the effect of specific microbes on egg viability (Cook et al 2003;Ruiz-de-Castañeda et al 2011a;Grizard et al 2014), incubation behaviour (Cook et al 2005), hatching success (Soler et al , 2015, and fledging success (Mills et al 1999;Moreno et al research has been conducted on the relationship between adult birds and their nesting environments. This is despite adult birds being both a source of microbes and the recipient of microbes originating from the nesting environment that could have a potential role in shaping avian life histories (Stewart and Rambo 2000).…”

“…Beauveria bassiana is a bacterium that produces bacteriocin inhibitory to pathogenic bacteria such as Listeria (Siragusa and Cutter 1993), which is was not isolated here but is prevalent in wild birds (Hellström et al 2008). Accordingly, B. campestris might be beneficial to birds in the same way as E. faecium (Moreno et al 2003) albeit via a different causal mechanism (toxin regulation rather than out-competition). Brochothrix campestris is a soil fungus that is pathogenic to many invertebrates and is used successfully in the poultry industry as a biocontrol agent for northern fowl mites; Ornithonyssus sylviarum (Rassette et al 2011).…”

PLEASE SCROLL DOWN FOR TEXT. Microbial relationships between birds and nesting environments are complex and remain poorly understood. Past studies have focused on between-nest variation in egg/chick bacterial profiles with little attention given to the microbial relationships between adult birds and their nests. Moreover, very little microbial research has included mycology despite fungi being prevalent in nesting environments and important correlates of fitness in chicks. In this study, we identified microbes associated with feathers, skin and nests of Pied Flycatchers Ficedula hypoleuca, an internationally-declining migrant songbird. From 75 samples, we isolated 50 bacterial OTUs (Operational Taxonomic Units; dominated by Enterococcus, Sanguibacter, Pseduomonas) and 63 fungal OTUs (dominated by Penicillium, Aspergillus), many of which had not previously been isolated from birds. Although females had significantly higher non-haemolytic bacterial OTU richness and males significantly higher fungal OTU richness, there was considerable diversity in actual OTUs isolated and thus there was no "typical" female, male, or nest microbial profile. Interestingly though, we show for the first time that the microflora of individual females is significantly more similar the microflora of her own nest than the site-level average of all nests. This suggests microbes are shared within female-nest pairs such that microbial communities start to converge. This is probably a two-way interaction as gut/skin microbes were isolated from nests and plant/soil microbes were isolated from females. Convergence was not seen for males, which probably reflects the role of the female as sole nest builder and egg incubator in this species. We discuss these findings in relation to microbial transfer pathways and avian nesting behaviour. The avian origins of some nest microbes, and species-specific differences in material used to construct nests, means that it is not surprising that there is considerable interspecific variation in nest microflora. This has been demonstrated in direct comparative studies by Goodenough and Stallwood (2010) and Peralta-Sánchez et al (2012), and is also evident by comparing single-species studies by...

“…Conversely, the presence of microbes can be beneficial; for example, Enterococcus faecium has been found to increase fitness of pied flycatcher (Ficedula hypoleuca) nestlings [39], while Eupenicillium javanicum contains the cyclic depsipeptide, Eujavanicin A, the antifungal properties of which are effective against Aspergillus fumigates, a cause of avian aspergillois [17,40].

Pathogenic bacteria constitute a serious threat to viability of many organisms. Because growth of most bacteria is favored by humid and warm environmental conditions, earlier reproducers in seasonal environments should suffer less from the negative consequences of pathogenic bacteria. These relationships, and the effects on reproductive success, should be particularly prominent in predators because they are frequently exposed to pathogenic microorganisms from sick prey. Here, we presented and tested this hypothesis by sampling bacteria on adult and nestling goshawks Accipiter gentilis. We predicted that early breeders and their offspring should have fewer bacteria than those reproducing later during the breeding season. Adult goshawks with a high abundance of Staphylococcus on their beak and claws were easier to capture and their laying date was delayed. Moreover, goshawks that laid their eggs later had offspring with more Staphylococcus on their beaks and claws. The strength of the association between laying date and bacterial density of nestlings was stronger during the warm spring of 2013, when nestlings suffered from a higher abundance of pathogenic bacteria. Hatching failure and fledging failure were more common in nests with a higher abundance of Staphylococcus independently of the number of years occupied, laying date, and age of the female nest owner. These findings imply that timing of reproduction may be under the influence of pathogenic bacteria. Because early breeding goshawks produce more recruits than later breeders, our results suggest a role for pathogenic bacteria in the optimal timing of reproduction.
