It's my mentor in the PH; I can't afford mentorship here (one on one consultation) but I can afford it there. However, I am still taking a course (on-line) from Parrot Volancy soon to know more about FF, Avian Nutrition, Behavior, etc. to increase my base knowledge.
FF is massive in the PH, but because most people can't afford expensive Macaws, Cockatoos, Golden Conures, (bigger parrots), most fly Cockatiels, Lovebirds, Budgies and Conures (GC and Sun). However, buying a Macaw in PH will be about at least $500-$1,000 less than buying it in North America. For example, a Hahn's will cost you about 35,000 pesos there, under $1,000 Cdn., wherein a Hahn's here will probably be $1,500-$3,000.
There are about 16 Birds of Prey species in PH, half are endemic, the rest wintering (no Falcon to my knowledge) but if you are in the south provinces near the province, I would not be flying my Macaw from there due to this Eagle that moves like a Goshhawk:
Ever greater areas of North America and Western Europe are becoming heavily populated by Birds of Prey and Free Flying has become dangerous for those with Parrots outside, let along free flying one's Parrots outside.
It takes extensive work to bring Parrots to a point that such activities -- with 'recall' training being the most important.
Parrot Forum has seen members ever those very well trained Parrots fly away and not return! The pain of loosing a Parrot is heart breaking and it is more heart breaking to watch as one's Parrots flies away.
So right 'Boats. For those considering Free Flight, take warning. Even the best trained parrot can become so scared by something (like being chased by a raptor, unexpected occurrences or other stuff ) that all training goes out the window and natural survival behavior takes over. THat behavior says "Fly away as fast as possible" and training be damned.
