Do you need to vaccine if you need to get a blue song?

Lan Ge 不 generally does not require vaccine, unless it is a high incidence of bird flu, in order to prevent illness from getting sick.This kind of bird is usually separate or paired. Most of the time, it will walk and jump on the ground, and rarely inhabit on the tree.I am good at hiding and can hide in the forest, not to be discovered by other creatures.It mainly eats insects, as well as spiders, mussel shells and small vertebrates.
