Fig. 3. Mass of emu hatchling components increase with fresh egg mass (M_e). Filled circles, hatchling (yolk-free hatchling + residual yolk) mass (M_h=0.64M_e+9.6; r²=0.82); filled triangles, yolk-free hatchling mass (M_yfh=0.46M_e+20.5; r²=0.64); open triangles, yolk-free hatchling dry mass (M_yfhd=0.12M_e+6.7; r²=0.43); filled squares, residual yolk mass (M_ry=0.18M_e–10.9; r²=0.24); open squares, residual yolk dry mass (M_ryd=0.11M_e–12.0; r²=0.28).
