The Bird Egg is one of the many bird eggs that can be collected on the island of Matumada. It can be found in the Featherpedia, despite not being a feather. It is only obtained from the Bird Nest as a possible egg out of the many that be revealed from the Bird Nest.
In appearance, the Bird Egg appears to be a regular white egg. Other than that, not much can be said about its overall appearance.
The Bird Egg does not have any relevant purposes in-game and as such, it can be sold to a selling vendor at a selling price of 3,500 gold.
