We included all raptors (accipitriformes), all owls (strigiformes) and falcons (falconiformes) as well as all herons, storks and allies (ciconiiformes), all ducks and allies (anseriformes) and all petrels, albatrosses and allies (procellariiformes). Finally we added two smaller and more obscure orders, the trogons (trogoniformes) and the tinamous (tinamiformes).
