“…This approach could be applied to quantify the circulation of a wide range of other infectious agents of interest for human or animal populations (e.g., avian influenza viruses: Hammouda et al, 2011; tick-borne viruses: Arnal et al, 2014). In addition, eggs can be used to quantify exposure to various mineral and organic pollutants (Ackerman et al, 2016; Bertolero et al, 2015; Morales et al, 2016, 2012; Ramos et al, 2013; Vicente et al, 2012) and to study food availability around colonies in interaction with density-dependence strength (Real et al, 2017). Because large gulls are abundant and widely distributed (e.g., Hebert, 2015; Navarro et al, 2016), this approach could be applied at larger spatial scales to track exposure to various infectious agents susceptible to circulate at the human-wildlife and terrestrial-marine interfaces.…”

Efficiently tracking and anticipating the dynamics of infectious agents in wild populations requires the gathering of large numbers of samples, if possible at several locations and points in time, which can be a challenge for some species. Testing for the presence of specific maternal antibodies in egg yolks sampled on the colonies could represent an efficient way to quantify the exposure of breeding females to infectious agents, particularly when using an abundant and widespread species, such as the yellow-legged gull ( Larus michahellis ). We used such an approach to explore spatio-temporal patterns of exposure to Toxoplasma gondii , a pathogenic protozoan responsible of toxoplasmosis in humans and other warm-blooded vertebrates. First, we tested the validity of this approach by exploring the repeatability of the detection of specific antibodies at the egg level using two different immunoassays and at the clutch level using an occupancy model. Then, samples gathered in 15 colonies from France, Spain and Tunisia were analysed using an immunoassay detecting antibodies specifically directed against T. gondii . Prevalence of specific antibodies in eggs was overall high while varying significantly among colonies. These results revealed that T. gondii circulated at a large spatial scale in the western Mediterranean yellow-legged gull population, highlighting its potential role in the maintenance community of this parasite. Additionally, this study illustrates how species commensal to human populations like large gulls can be used as wildlife sentinels for the tracking of infectious agents at the human-wildlife interface, notably by sampling eggs.

“…A remarkable result is the higher concentrations and detection frequencies of PFUnDA and PFOS found in adult females compared with males (Figure S2), although most pronounced at the plant site, these differences were consistent at all sites and in both sampling periods. Most of the studies on PFAA concentrations in birds did not observe differences between sexes (reviewed in Sturm and Ahrens 51 ), and the ones that did always have reported higher concentrations in males [52][53][54][55] .…”

The ubiquity of perfluoroalkyl acids (PFAAs) contrasts with the limited information about their effects. We report here PFAA plasma concentrations in wild populations of great tits (Parus major) settled at and in the vicinity of a fluorochemical plant in Antwerp (Belgium). Using two generations we obtained novel results on some poorly known issues such as differences between sexes, maternal transfer of the compounds and potential associations with the oxidative status. For five out of the 13 detected PFAAs, the concentrations were the highest ever reported in birds' plasma, which confirms that Antwerp is one of the main hotspots for PFAAs pollution. Contrary to other studies conducted in birds, we found that females presented higher mean concentrations

“…Larger (non‐passerine) species, such as gulls (genus Larus ), can fly up to tens of kilometers to forage while breeding (Méndez et al, 2020), and they may target a specific foraging area (i.e., a refuse dump site) for prolonged periods. The contamination level of these species may thus be highly variable, even among individuals breeding at the same site, and is linked to the contamination level of individual‐specific foraging areas (Bertolero et al, 2015; Parolini et al, 2020) rather than that of the breeding sites. Insectivorous and predatory birds are probably best suited to PFAS monitoring, because they are high‐level consumers, and PFAS uptake occurs mainly via food, leading to biomagnification along the trophic chain (Ankley et al, 2021).…”

“…Several studies have demonstrated that eggs of different bird species represent a valuable, noninvasive tool for monitoring PFAS contamination in different geographical areas (e.g., Bertolero et al, 2015; Custer et al, 2013; Gebbink & Letcher, 2012; Lopez‐Antia et al, 2017; Nordén et al, 2013; Parolini et al, 2020; Vicente et al, 2012). Most studies have used eggs from seabirds, whereas studies analyzing eggs of terrestrial species, especially passerines, are less frequent (Ahrens et al, 2011; Custer et al, 2012; Holmström et al, 2010; Lasters et al, 2019; Rüdel et al, 2011; Yoo et al, 2008).…”

For many years, eggs of diverse bird species have been used as monitoring tools in studies investigating perfluoroalkyl substances (PFAS) contamination, especially in marine and remote areas. Avian eggs are a suitable monitoring matrix because they are relatively easy to collect and their yolks store diverse maternally transferred PFAS. Moreover, the concentrations of PFAS detected in the eggs are a good proxy for maternal exposure and allow the assessment of the potential risk for birds. These features support the use of avian eggs as a key monitoring tool in exposure assessment of PFAS‐contaminated sites. We first review the recent application of avian eggs in PFAS monitoring in environmental risk assessment schemes, highlighting strengths and limitations and suggesting which criteria should be considered when selecting a proper study species and structuring the sampling and analytical protocol. Eventually, we report findings from a field study realized in 2020 near a perfluoropolymer factory site in the upper Po plain (Northern Italy), revealing an unprecedented contamination level of PFOA and C6O4 in three species of wild passerines. In future, long‐term monitoring of PFAS contamination using avian eggs should be maintained, to provide crucial information on the temporal trend of fluorochemical production and waste disposal, while facilitating early identification of emerging PFAS as well as the quantification of their biomagnification across the trophic web.
