The barn swallow (Hirundo rustica) poses a number of fascinating scientific questions, including the taxonomic status of postulated subspecies. Here we obtained and assessed the sequence variation of 411 complete mitogenomes, mainly from the European H. r. rustica, but other subspecies as well. In almost every case, we observed subspecies-specific haplogroups, which we employed together with estimated radiation times to postulate a model for the geographical and temporal worldwide spread of the species. The female barn swallow carrying the Hirundo rustica ancestral mitogenome left Africa (or its vicinity) around 280 thousand years ago (kya), and her descendants expanded first into Eurasia and then, at least 51 kya, into the Americas, from where a relatively recent (< 20 kya) back migration to Asia took place. The exception to the haplogroup subspecies specificity is represented by the sedentary Levantine H. r. transitiva that extensively shares haplogroup A with the migratory European H. r. rustica and, to a lesser extent, haplogroup B with the Egyptian H. r. savignii. Our data indicate that rustica and transitiva most likely derive from a sedentary Levantine population source that split at the end of the Younger Dryas (11.7 kya). Since then, however, transitiva received genetic inputs from and admixed with both the closely related rustica and the adjacent savignii. Demographic analyses confirm this species’ strong link with climate fluctuations and human activities making it an excellent indicator for monitoring and assessing the impact of current global changes on wildlife.

Urbanization affects the natural world, with implications for habitat availability and wildlife behavior, notably in the context of South Korea. This study investigates the effects of urbanization on the nest sizes and materials of barn swallows, a migratory bird species. Utilizing comparative analyses across suburban, exurban, and rural regions, the study found substantial variations in nest volumes. Specifically, rural areas had significantly larger nests than suburban areas, whereas exurban nest sizes fell in between. Although a potential explanation might relate to differences in the availability of nesting materials, this hypothesis necessitates further investigation. The study also found that the soil composition in nests varied by location, with sand, silt, and clay content showing marginal differences, but not statistically significant disparities. However, a clear preference for a specific soil texture was evident, along with the finding that forest cover within a 1 km radius of the nest was correlated with larger nest sizes. Land use was further linked to the external volume of barn swallow nests, pointing to a potential interaction between habitat quality and nest construction. Overall, the findings underscore the complexity of urbanization’s impact on barn swallows, emphasizing the need to conserve natural habitats and devise strategies to mitigate the negative effects on these birds. These results contribute to the growing understanding of urban ecology and the urgent need for thoughtful management of human-altered landscapes.

Effects of a novel ectoparasite on condition and mouth coloration of nestling barn swallows

Parasites have profound and widespread implications for the ecology and evolution of hosts, and human activity has increased the frequency of interactions between hosts and parasites that have not co-evolved. For example, by building habitat attractive for nesting, humans might have facilitated range expansion by cliff swallows (Petrochelidon pyrrhonata) and barn swallows (Hirundo rustica) in North America, concurrently allowing a haematophagous ectoparasite of cliff swallows, the swallow bug (Oeciacus vicarious), to infest the nests of barn swallows. We found that in barn swallow nests infested with swallow bugs, nestlings weighed less and had lower haematocrit, and the within-brood variation in body mass and tarsus length was higher. Information about these negative effects might be available to parents via mouth coloration, a condition-dependent component of the begging signal. We found that nestlings from infested broods had lower-intensity carotenoid-based and ultraviolet mouth colours, although most elements of colour were unrelated to parasites. Host switching by the swallow bug offers excellent opportunities to understand the direct and indirect effects of a novel parasite and might also afford insights into how parasites cope with selective pressures exerted by closely related hosts with key ecological differences.
