Very good, Ollie!!
Michele, I taught Jerry recall the same way as Camille. Now we usually just hold up our hand with a finger sticking out like as perch, say "Come here, Jare!" and he flies right over and hits that perch every time

Although he's not 100% recall trained, he comes about 70-80% when he's not distracted. But we don't reinforce the training as much as we should so at the moment we're perfectly happy with the percentage of recall.
