What does "skybird" mean? Is it a bird in general?
Answer from a Native speaker
I believe she is referring to birds that can fly. For example, birds such as doves, robins, pigeons, swallows, etc. In this song, she is singing about how flying birds drop seeds for trees, plants, or flowers. It's not very common to call flying birds "sky birds." We usually just say birds or will name the specific type of bird, whether that bird can fly or not. Ex: Robins are considered sky birds. Ex: Ostriches and penguins are not sky birds since they cannot fly.
