From: Winter body mass and over-ocean flocking as components of danger management by Pacific dunlins
Whole body fat content of Pacific dunlins. Distributions of whole body fat content of dunlins collected in the late 1970s (black symbols; from McEwan & Whitehead [29]) versus the 1990s (grey symbols). Error bars are standard deviations. Females are indicated by a circle and males by a triangle. Two individuals from the 1990s dataset could not be gender-assigned and are designated by a star. Details of the data sets are given in the Methods.
