Body to liver mass relationship in guillemots dying of different causes. Plots show the significant, positive relationship between body and liver mass. Light grey areas indicate standard errors around the regression line. Birds that died of drowning had heavier livers than other birds for a given body mass, while the body mass – liver mass relationship did not differ between birds that died of drowning compared to other causes
