“…These results are consistent with the findings of a recent study on homing pigeons, Columba livia, which did not find a difference in plasma haptoglobin concentration or levels of agglutination between birds that raced and those that did not (Matson et al, 2012). The magnitude and the duration of the change in body temperature in response to LPS injection can vary with a number of factors, such as age (Fraifeld and Kaplanski, 1998;Nebel et al, 2013), dose (Maloney and Gray, 1998), population (Adelman et al, 2010b;Adelman et al, 2010a) and season (Owen-Ashley and Wingfield, 2007).…”

“…For example, a study on red knots, Calidris canutus, found that induced humoral and cell-mediated responses were not affected by flight in a wind tunnel (Hasselquist et al, 2007). This highlights that the effects of flight on immune function -and vice versa -remain poorly understood (Matson et al, 2012).…”

“…Repeatability scores of our counts were highly significant (H/Ly ratio F 91,92 =8.28, P<0.01, intraclass correlation coefficient=0.78; Lessells and Boag, 1987). A high H/Ly ratio is often interpreted as a sign of physiological stress Lobato et al, 2005;Campbell and Ellis, 2007) and, for example, sustained flight has been shown to increase the H/Ly ratio (Matson et al, 2012).…”

In the context of sexual and natural selection, an allocation trade-off for carotenoid pigments may exist because of their obligate dietary origin and their role both in the antioxidant and immune systems and in the production of coloured signals in various taxa, particularly birds. When birds have expended large amounts of carotenoids to feather growth such as after autumn moult, bird health and oxidative status might be more constrained. We tested this hypothesis in a bird species with carotenoid-based plumage colour, by manipulating dietary carotenoids and physical activity, which can decrease antioxidant capacity and increase reactive oxygen metabolite (ROM) concentration. Great tits were captured after moult and kept in aviaries, under three treatments: physical handicap and dietary supplementation with carotenoids, physical handicap and control diet, and no handicap and control diet. We measured plasma composition (antioxidant capacity, ROM concentration, and vitamin A, vitamin E and total carotenoid concentrations), immune system activation (blood sedimentation) and stress response (heterophil/ lymphocyte ratio) and predicted that handicap treatment should influence these negatively and carotenoid supplementation positively. Coloration of yellow feathers was also measured. Carotenoid supplementation increased total plasma carotenoid concentration, decreased feather carotenoid chroma and marginally increased ROM concentration. Handicap increased blood sedimentation only in males but had no clear influence on oxidative stress, which contradicted previous studies. Further studies are needed to investigate how physical activity and carotenoid availability might interact and influence oxidative stress outside the moult period, and their combined potential influence on attractiveness and reproductive investment later during the breeding season.

“…Haptoglobin is a heme-binding acutephase protein with multiple physiological functions (Quaye 2008), including preventing free heme from serving as a nutrient for infectious microorganisms (Eaton et al 1982). Compared to agglutination titers, haptoglobin concentrations are considerably more labile over short timescales (van de Crommenacker et al 2010;Matson et al 2012aMatson et al , 2012b. A growing body of research explores both indexes in the contexts of avian ecology (Hegemann et al 2012;Horrocks et al 2012b), life history (Palacios et al 2007;Versteegh et al 2012), and geography (Matson 2006;Horrocks et al 2012a).…”

Island organisms face a range of extrinsic threats to their characteristically small populations. Certain biological differences between island and continental organisms have the potential to exacerbate these threats. Understanding how island birds differ from their continental relatives may provide insight into population viability and serve as a predictive tool for conservation efforts. We compared an eastern bluebird population in Ohio with a threatened population in Bermuda in terms of the birds' development, morphology, immunology, and reproduction. These comparisons revealed that island nestlings had shorter wings and island adults had longer wings than their continental analogs. Island nestlings also had shorter tarsi than continental nestlings at day 8 posthatch, but this difference was absent at day 15 and in adults. Adults weighed less in Bermuda than in Ohio, and both nestlings and adults in Bermuda exhibited higher levels of two immunological indexes (concentrations of an acute-phase protein and titers of nonspecific antibodies). Clutch sizes and hatch rates did not differ between the island and continental populations; however, as the breeding season progressed, brood sizes declined in Bermuda, whereas no such decline occurred in Ohio. Despite these differences and differences in nestling development, island and continental parents fed their nestlings at equal rates. Overall, our results suggest that the Bermuda phenotype may be adjusted to certain aspects of the island environment but not to others. Efforts to conserve the bluebirds of Bermuda may be improved by focusing on the intraseasonal patterns in nestling mortality and, more generally, the survival probabilities of different age classes.
