After incubating for 18 days, finally I saw the first evident of successful hatching yesterday. The female Iora brought out the egg shell to make room for the new member of family.
I saw the feeding frenzy with the male and female bringing food to their baby every 15 to 20 minutes.
Here female with green larva.
Male with brown insect.
The Pair - female with food. They still sit inside the nest, guarding it. Not even a second the nest left unintended. If the male is looking for food, the female sit inside the nest and vise versa.
The chicks are still small and not visible from outside.
