Passeriformes I Tyrannidae Laniidae Vireonidae Corvidae Alaudidae
Passeriformes: Passerine or perching birds • Field Marks: • Range in size from tiny Bushtit to the Common Raven • Feet anisodactyl and neither lobed, webbed, nor semipalmate • Hallux usually incumbent and equal to or longer than rest of toes • Foot structure referred to as “perching foot,” unique to this group • Wings have either 9 or 10 primaries • Life History: • Includes insectivores, granivores, frugivores, carnivores, and omnivores • Young are altricial, naked and reared in the nest • Roughly 60% of all birds belong to this order, the world’s largest order of birds • Divided into two suborders: suboscines and oscines • Distribution: • Present everywhere, except Antarctica and the oceans
