Interestingly, the New Zealand Falcon (Falco novaeseelandiae) is immune to all respiratory illnesses and blood disorders. Researchers confirmed this is due to the falcon's diet of possums and salmon, which are native to New Zealand. Even more astounding, it's wingspan ranges from 63 cm (25 in) and 98 cm (39 in) and its weight rarely exceeds 450 g (16 oz).

The mysteries of the falcon endure for eternity in our hearts and minds
