To summon birds to your forest, you will need to use your Summoning Tree! The Summoning Tree is a majestic Tree Spirit who you will help restore the forest to a lively world of wonder with!
Your Summoning Tree Spirit can be found in the centre of your forest. You can place up to 3 Enchanted Feathers during a Summon which can be used to control the possibility of a certain bird type. Enchanted Feathers generally come from the Enchanter Fox, but can also be earned as some Mission and Achievement rewards, purchased as a possible Daily Deal item, or may arrive in gifts from friends!
When initially Summoned the bird will arrive as an egg which needs to incubate before you can hatch it.
