The female is incubating their eggs in the nest inside a tree cavity–you can just see the tip of her beak. She is encased behind a wall of mud that keeps the eggs and young chicks safe from predators. The female does not leave the nest until after the chicks have hatched and grown (usually 3 or 4 months), and during this time she is completely dependent on her partner for food, delivered through the small opening to the nest–seeds, fruits, lizards, frogs, and insects. @natgeo supported me with a grant for this work #Bhutan #Conservation #RoyalManasNationalPark #Himalayas Follow me @christianziegler for more wildlife and nature stories.」6月16日 5時01分
