All of the species in these groups have one important thing in common: nine functional primary feathers. (However, they possess a reduced and hidden 10th primary, so they are really 10-primaried, like the majority of other passerines [Hall 2005].) Looking past this one uniting feature, we see a huge assemblage of birds which is very diverse! These birds have been grouped and classifed by bill type and function, and the major groupings are: 1• New World Warblers (a.k.a. wood-warblers or parulids). Thin, pointed bills designed for probing for insects. 2• Icterids (a.k.a. New World orioles and blackbirds). Long, pointed, conical bills that are often employed in gaping. 3• Emberizids (New World sparrows, towhees, longspurs, Old World buntings).
