Figure 7. The relative contribution of cup depth on heat loss to the ground (upper left), of cup depth on wind cooling at 5 m/s (lower left), of lining depth (upper right)and of lining material (lower right) on egg cooling rates in relation to body mass.

LS  =  little stint, PH  =  red phalarope, DU  =  dunlin, CS  =  curlew sandpiper, TU  =  turnstone, PGP = Pacific golden plover. Average and se values are represented for each species. The lines represent the regression lines.
