“…In oil sands-related studies, hepatic EROD induction was increased in nestling tree swallows inhabiting wetlands receiving industrial effluents (Gentes et al, 2006;Smits et al, 2000), but not different in ducklings raised on such wetlands, even when PAHs (pyrene and naphthalene) were found in bile (Gurney et al, 2005). Similar to our results, natural exposure to air contaminants also induced hepatic EROD activity in tree swallows exposed to contaminant emissions from the oil sands (Cruz-Martinez et al, 2014).…”

“…In a field study, tree swallows naturally exposed to air contaminants from oil sands operations had a suppressed T cell response and smaller bursa of Fabricius (Cruz-Martinez et al, 2014). Consistent with the lack of functional changes in T and B cell responses in the current study, and in a previous study on naturally exposed tree swallows (Cruz-Martinez et al, 2014), there were no histological alterations in immune organs.…”

“…Moult begins immediately subsequent to, or in some cases during, breeding (Hussell, 1983). The species’ wide distribution and resilience to study has led to their extensive use in ecological applications such as impact assessment, where physiological biomarkers would be useful tools (Ghilain and Bélisle, 2008; Harms et al ., 2010; Custer, 2011; Paquette et al ., 2013; Cruz-Martinez et al ., 2015). Finally, tree swallow flight feathers are uniformly dark, preventing confounding effects of pigment differences when comparing feather CORT levels (Jenni-Eiermann et al ., 2015).…”

“…Furthermore, starlings have also been used in exposure studies for EDCs, both in outdoor aviaries (Van den Steen et al, 2009) as well as exposure of nestlings in the field and subsequent transfer to the laboratory (Eng et al, 2014). Other passerines that have often been used in linking exposure to effects in a field context are great tits (Parus major), pied flycatchers (Ficedula hypoleuca), and tree swallows (Tachycineta bicolor) (see for example Rainio et al, 2013;Gilchrist et al, 2014;Cruz-Martinez et al, 2015a;Vermeulen et al, 2015).…”
