Fig. 64. Stuffed Goshawk {Asiur africapn/t(.s, young) in winter pine woods, 

 seen from below as the hare or grouse would see him, wonderfully matching, 

 with the help of counter-shading, his barred background of twigs, skv-glints, 

 etc.

Fig. 66. The same young Gos- 

 hawk (Astnr atricapillv^) laid on its 

 back on the forest floor and looking

 in the 'twig matching' shown bv 

 Fig& 64-65.
