To overcome this confusion, it has been proposed to merge the "core" Pelecaniformes into the Ciconiiformes.
The existing avifauna can be grouped into podicipediformes, pelecaniformes, phoenicopteriformes, falconiformes, anseriformes, galliformes, gruiformes, charadriiformes, columbiformes, cuculiformes, strigiformes, caprimulgiformes, apodiformes, coraciiformes, piciformes, passeriformes. 39 species are included in the Red Book of Armenia.
