Feather isotope ratios and sexing of oystercatchers breeding in Iceland, 2013-2017
Dataset comprises of the delta-13C and delta-15N stable isotopic information from feather samples (for 552 individuals) and the sex (assigned by DNA-analysis of blood samples for 321 individuals) of oystercatchers (Haematopus ostralegus) breeding in Iceland during the summers of 2013-2017. The Icelandic oystercatcher population contains individuals that stay in Iceland year-round and individuals that migrate to mainland Europe in the non-breeding season, and feather isotope ratios provide a means of distinguishing between these migratory behaviours (as confirmed by observations of marked individuals).
These data were collected by a collaborative team from the University of Iceland, University of East Anglia (UK) and the University of Aveiro (Portugal).

Provenance & quality
Feathers were washed in a 2:1 chloroform/methanol solution, left to dry overnight in a fume cupboard and cut into small fragments. Each sample was then weighed and loaded into a combustion Costech elemental analyser coupled to a Thermo Scientific Delta XP continuous flow isotopic ratio mass spectrometer and a Conflo III interface. DNA was extracted from blood samples using a standard ammonium acetate technique (dx.doi.org/10.17504/protocols.io.knycvfw) and diluted to a working concentration of 10–50 ng/μL, and used to assign sex following the methods set out in Fridolfsson & Ellegren (1999: DOI: 10.2307/3677252).
