IntroductionIn order to gain an understanding of the economic basis of prehistoric communities, the identification of dairying is essential, particularly in northwest Europe, where a high degree of lactose tolerance suggests that fresh milk has long been a significant dietary component. Currently, prehistoric dairying is investigated using a variety of techniques.The two techniques that have been most widely applied are the examination of faunal remains and compound-specific stable isotope analysis of lipids in pottery residues.Examination of faunal remains to determine age-at-death slaughter patterns (mortality profiles) and female to male ratios (Higham 1968;Payne 1973) allows the economic role of a particular species (e.g. for meat, wool, milk or traction) to be inferred (e.g.Legge 1981), whilst lipid analysis is effective at identifying the presence of milk products in the archaeological record (e.g. Dudd and Evershed 1998;Copley et al. 2005a). Recent developments in the detection of archaeological proteins have allowed the identification of milk proteins to species in both organic residues and human dental calculus (e.g. Hong et al. 2012;Buckley et al. 2013; Warinner et al. 2014).An additional approach to identify cattle (Bos taurus) dairying in prehistoric communities is explored in this paper: a possible relationship between calving seasonality, i.e. the distribution of births throughout the year, and economic focus. For economies focussed on the year-round production of fresh milk as a staple food product, it has been postulated that multiple-season calving would have been necessary (Towers et al. 2011;Balasse et al. 2012a;Gron et al. 2015). In contrast, a strategy of singleseason calving, probably in spring, may have been favoured for meat-based economies or economies focussed on storable milk products. Increasingly, birth seasonality of domestic herbivores has been investigated using intra-tooth isotope ratio analysis of molar enamel (e.g. Balasse et al. 2003;Balasse and Tresset 2007;Blaise and Balasse 2011;Towers et al. 2011;Balasse et al. 2012a;Balasse et al. 2012b;Tornero et al. 2013;Towers et al. 2014;Buchan et al. 2015;Gron et al. 2015).Each of the aforementioned techniques to identify p...

“…Mizutani and Wada (1988), Mizutani et al (1990Mizutani et al ( , 1992 and Hobson and Clark (1992b) also observed significant differences in ε 13 C for regurgitant and feathers from free ranging and captive birds. Variability was attributed to a variety of factors including the relationship between the timing of feather growth and seasonality in the composition of potential prey and/or the lipid content of prey items (Bender et al 1981;Sullivan and Krueger 1981;Hobson and Clark 1992a). DeNiro and Epstein (1981) were the first to demonstrate that animal tissues are enriched in 15 N compared with their diets.…”

Foraging ecology of the endangered wood stork recorded in the stable isotope signature of feathers

Down feathers and regurgitant were collected from nestling wood storks (Mycteria americana) from two inland and two coastal breeding colonies in Georgia. The stable isotopic ratios of carbon ( 13 C/ 12 C) and nitrogen ( 15 N/ 14 N) in these materials were analyzed to gain insights into the natal origins of juvenile storks and the foraging activities of adults. Down feathers differed in δ 13 C between inland and coastal colonies, having average isotopic values that reflected the sources of carbon fixed in biomass at the base of the food web. Feathers from the inland colonies differed between colonies in δ 15 N, while those from the coastal colonies did not. These patterns primarily reflected the foraging activities of parent storks, with individuals capturing differing percentages of prey of distinct trophic status at each colony. Collectively, the carbon and nitrogen isotopic signatures of feather keratin were used to distinguish nestlings from each colony, except for instances where storks from different colonies foraged in common wetlands. The stable isotopic composition of food items in regurgitant was used to reconstruct the trophic structure of the ecosystems in which wood storks foraged. Predicted foraging activities based on the isotopic composition of keratin were generally consistent with the percentage of prey types (freshwater vs. saltwater and lower trophic level vs. upper trophic level consumer) observed in regurgitant, except for the coastal colony at St. Simons Island, where the δ 13 C of feathers strongly suggested that freshwater prey were a significant component of the diet. This inconsistency was resolved by aerial tracking of adults during foraging excursions using a fixed-wing aircraft. Observed foraging activities supported interpretations based on the stable isotope content of feathers, suggesting that the latter provided a better record of overall foraging activity than regurgitant analysis alone. Observed foraging patterns were compared to the predictions of a statistical model that determined habitat utilization based on habitat availability using a geographic information system (GIS) database. Observed foraging activities and those predicted from feathers both suggested that some adult storks preferred to feed their young freshwater prey, even when saltwater resources were more accessible in the local environment. This conclusion supports the contention that wood stork populations are sensitive to changes in the distribution of freshwater habitats along the southeastern coastal plain of the United States.
