Galician terms for types or instances of birds.

NOTE: This is a set category. It should contain terms for birds, not merely terms related to birds. It may contain more general terms (e.g. types of birds) or more specific terms (e.g. names of specific birds), although there may be related categories specifically for these types of terms.
