Study Notes
Classification of Birds
- Kingdom: Animalia, encompassing all animal life.
- Phylum: Chordata, indicating animals with a notochord (spinal structure).
- Subphylum: Vertebrata, referring to animals with a backbone.
- Class: Aves, representing the class of birds.
Subclasses and Superorders
- Subclasses of Aves:
- Archaeornithes ("Old Birds"): Extinct group.
- Neornithes ("New Birds"): The surviving lineage of birds.
Superorders of Neornithes
- Odontognathae ("Toothed Jaw"): An extinct superorder.
- Palaeognathae ("Ancient Jaw"): Characterized by a primitive palate; mostly flightless, with all but tinamous incapable of flight.
- Neognathae ("New Jaw"): Comprises modern birds with a flexible palate.
Key Features of Superorders
-
Palaeognathae:
- Consists of cursorial landbirds.
- Distinctive palate morphology and reproductive behaviors.
- Includes five orders with a total of 60 species.
-
Neognathae:
- Divided into clades:
- Galloanseres (Fowl): Comprises Galliformes (pheasants and allies) and Anseriformes (ducks and screamers).
- Neoaves (New Birds): Contains three supra-ordinal clades.
- Basal unresolved (9 groups).
- Aequornithes: Core waterbirds.
- Telluraves: Core landbirds.
- Divided into clades:
Noteworthy Bird Orders and Families
-
Palaeognathae includes:
- Struthioniformes (Ostriches)
- Rheiformes (Rheas)
- Casuariiformes (Cassowaries & Emus)
- Apterygiformes (Kiwis)
- Tinamiformes (Tinamous)
-
Unique Order:
- Opisthocomiformes (Hoatzin): Only one species, currently indeterminate in classification.
Passeriformes Subgroups
- Two major subgroups:
- Suboscines (Suborder Tyranni): Simple syrinx structure, less complex song production through external muscles.
- Oscines (Suborder Passeres): Complex syrinx with internal muscle control, includes relatives like crows and thrushes.
Additional Facts
- North American Subfamily of Suboscines: Tyrannidae.
- Notable Fossil: Archaeopteryx, significant to the study of bird evolution.
- Total bird families: Over 250.
- Number of bird species: Approximately 10,315 to 10,725, plus 158 extinct species, exceeding a total estimate of 10,000 species.
