Large wheatfield at Meckering, WA, plays host to Rod MacDonalds lost model. Black dot in centre is fetchermite Denzyl Moncrieff, with model.

Denzyls new cousins, waiting their turn to fly. A pigeon pair, should be naturals!

 Denzyl with Rod's recovered model. Another week and the wheat would swallow the model forever.
