To the best of my knowledge, Aves is a class. (Though taxonomy is fickle at best, taxa being constantly restructured and reevaluated.) You might mean the subclasses Paleogna…thae and Neognathae, though these too are nowadays considered superorders, of the subclass Neornithes, rather than subclasses themselves. (MORE)

Aves Aves is part of the hierarchical system of classification, specifically the subphylum Vertebrata of the Phylum Chordata (animals that have back bones). Aves is the name… of the class to which birds belong in taxonomy; the Class Aves. Aves is divided into 29 orders, with Passeriformes the largest with about 5000 species. Some of the other orders have as few as one species (like Struthioniformes, the ostrich order). The aves are commonly known as the "birds" (after all, that is what they are). Characteristics .
Both morphologically and biologically, they are highly adapted for flight although many species have lost the powers of flight. .
They have scaly legs and feathers (which are specialized scales). Their bones are light (an adaption for flight), and are honeycombed in most species. The fore-limbs are highly modified that, along with their associated feathers, in most species are adapted for flight. .
Further adaptations for flight include the urinary system that excretes nitrogenous waste as uric acid crystals, massive reduction in size of reproductive organs when not breeding, the development of only one ovary or testis when breeding, and a massive sternum to anchor flight muscles. .
All species lay eggs .
They are toothless animals, but have a beak .
As certain times of year some species lay-down a fat layer for insulation and/or a food reserve that can be utilized in long migratory flights .
They have a highly efficient cardiopulmonary system, with an endothermic heart (they are warm-blooded). (MORE)
You would have to be more clear on what you mean by "aves". That word could have many connotations, for instance, it could be referring to the Latin word for hello, it could a…lso be a declension of a Latin word, it could possibly have something to do with birds, or it could refer to the prayer, Hail Mary.

The AV-D:A is know as the Anti-Viral District of America.Supposidly a top secret organization that studies on viral diseasesand BioHazards. No one knows much about the AV-D:A.… They have 4major lab stations that are closed off to the public. --> VSL:AA (Viral Systematic Labs of Anchorage Alaska) --> AVLC (Anti-Viral Labs of California) .
--> A:51 (Area 51 [Legend]) --> DRLM (Disease Research Labs of Miami) These places are known as "Classified" but evidence of theseorganizations are all over the place. .
Their offical work line is unknown and their cause is alsounknown. (MORE)
