25. Other Classification Schemes place: Some classification schemes place Sandgrouse in their own Order Pteroclidiformes or with the Orders Columbiformes or Charadriiformes.
There are 16 spp. in Asia and Africa, inhabit plains and deserts. Superficially they appear pigeon-like.
The traditional classification schemes have placed flamingos in the Ciconiiformes along with the herons, storks, and ibises.
Some classification schemes split hummingbirds and swifts into separate Orders, Trochiliformes and Apodiformes, respectively.
27. Superorder Neognathae Order Passeriformes - Songbirds (Perching birds), about 5700 spp. (> 50% of all birds), world-wide
Divided into primitive Suboscine Suborder (Tyranni) and advanced Oscine Suborder (Passeres) - Oscines with better vocalizations because of highly developed syrinx
Feet adapted for perching (3 in front, 1 in back)
Wing with 9 or 10 primaries
Unique palate and sperm structure
Very altricial hatchlings
28. Songbird Classification Two main divisions:
Primitive Suboscines
Advanced Oscines
Primitive Suboscine songbird group dominant in South America
Advanced Oscine songbird group outcompetes Suboscines and are dominant everywhere else
30. Research Project Why are Suboscines dominant in South America?
South America isolated from other continents
31. Research Project Why do Oscines outcompete Suboscines?
One hypothesis = Metabolic Capacity Hypothesis = Suboscines have “restrictive tropical physiology” (Feduccia 1999)
Tested hypothesis by measuring max MR in cold
Prediction: If hypothesis valid, Oscines should have higher MR than Suboscines
Why Chile? – High proportion of Suboscines and temperate climate
