19 orders

Birds: Classification Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Aves Within the class there are 29 Orders 187 Families 9600 Species

Taxonomy of the Robin Level Name Description Kingdom Animalia Animals Phylum Chordata Subphylum: Vertebrata Animals with backbones Class Aves Animals called Birds Order (29) Passeriformes Birds that perch Family (187) Turdidae All Thrushes Genus Turdus Similar Thrushes Species (9600) Turdus migratorius American Robin

Characteristics Unique to Birds Have Feathers Right aortic arch in heart

Shared with Mammals Endothermic 4 chambered heart

Shared w/ Mammals Cont. Large amount of parental care

Shared with Reptiles Egg laying Egg tooth helps break out of shell Scales: feathers and on feet Skeletal characteristics (many) Air sacs (similar to turtles and chameleons)

Historical Incomplete fossil record Soft bones do not fossilize well Archaeopteryx: (ancient wing) 1. most primitive bird we know of BUT not necessarily the ancestor of birds 2. Discovered in 1861 in Germany: fossil of skeleton with feathers 3. From Jurassic period: 150 mya

Archaeopteryx Cont. 4. About the size of a crow Long tail and teeth like a reptile Feathers asymmetrical (characteristic of flight)

Feather Functions Carrying Water (African Sand Grouse) Specially adapted breast feathers can absorb up to 40ml of water. After wading through watering holes to absorb water, the male will return to the nest so the chicks can drink the water from the feathers.

FEATHERS Feathers are an adaptation of reptilian scales Sizes range from 1/20 of an inch on an eyelid to 5 feet on a peacock tail! 1,000 to 25,000 feathers per bird

Feather Types 1. Contour Feathers: smooth, patterned to contribute to appearance

Feather Types 2. Flight Feather: hollow central shaft (rachis) Flat vein on either side Barb comes off the vein, contains barbules

Feather Types 3. Down: very short rachis (shaft) NON-INTERLOCKING BARBS Insulation: traps air
