Debbie Stewart has spent the last 3 decades protecting, and rehabilitating New Zealand's threatened birds of prey
She set up the Wingspan National Bird of Prey Centre in Rotorua where she pioneered the breeding of New Zealand Falcons (Karearea) and Morepork (Ruru) and has been releasing them back into the wild.
The centre has just won an Canon environmental grant to film Karearea in their natural habitat throughout the year - a sight rarely seen - from hatching at the nest to fully fledged adults.
