Non-Passerines

Non-passerines are all the bird species that do not belong to the order Passeriformes. About 40% of all bird species fall into this group. They have feet which do not have all the toes extending at the same level, they may have webbed toes or have two toes forward and two toes back or have toes that join the leg at different levels . Additionally they generally do not have voice boxes that are developed to the same level as most Passeriformes species have.

Non-passeriformes is not really an order as Passeriformes is, rather it is a collection of orders, used to organise birds into categories that are more convenient. The collection includes birds like the doves, parrots, ducks, emus, waders and seabirds.
