Seasonal, size‐ and age‐related patterns in body‐mass and composition of Purple Sandpipers Calidris maritima in Britain
The masses of 3229 Purple Sandpipers Calidris maritima from Britain were analysed for differences related to age, season and size. First‐year birds were lighter by 2 g. There was only a slight increase in mass in mid‐winter, in contrast to other waders wintering in Britain, suggesting that Purple Sa...
