About this document
Characteristics and Classification of Aves by kiogora is a document available to read on EtoBox.
Class Aves includes approximately 9000 species of birds characterized by bipedalism, feathers, warm-bloodedness, and adaptations for flight such as wings and a lightweight skeleton. They possess unique physiological traits like a four-chambered heart, specialized respiratory systems with air sacs, and a single functional ovary in females. Class Aves is classified into two subclasses: Archaeornithes, which are extinct with toothed beaks, and Neornithes, which includes modern birds without teeth.
