Just in case the Introduction to Bird Classifications/Families was missed, the following table, which has been colorized for easy reference, lists only Eastern US birds in their Orders, followed by the scientific and common Family name, and then by scientific and common Subfamily name. The Genus and Species (both scientific and common) of all Eastern US birds will be listed in a separate window by moving your mouse over the Order Name. Also, the Passeriformes Order has been broken down into three (3) parts due to it's large size. For easy reading, the scientific names are not italicized. The standard convention for writing or printing scientific names requires that only the genus name be capitalized and the species should begin with lowercase. The entire scientific name should be underlined or in italics.
