Class Aves
The structure of a bird's bill depends on this
What is the way it gathers food?
The special way birds molt their feathers
What is in pairs and only a couple at a time?
Organisms that can generate their own heat internally are referred to as this
What are endotherms?
3 (of 5) characteristics that are found in mammals
What is hair covering skin, internal fertilization and usually viviparous, mammary glands, endothermic, and 4-chambered heart?
The type of behavior which accounts for sea turtle hatchlings to return to the ocean?
What is innate?
3 (of 6) general characteristics of birds
What are endothermic, 4-chambered heart, toothless bill, oviparous (egg-laying), feathers, and porous skeleton?
This wing/feather structure reduces turbulence as a bird lands
What is the alula?
4-chambered hearts allows for this related to the blood oxygen concentration
What is oxygen-rich and oxygen-poor blood remains separated?
This type of hair helps provide insulation
What is underhair?
A learned behavior that is usually irreversible and limited to a specific time period in an animal's life
ALSO, give an example of this behavior
What is imprinting?
Goslings will begin to follow the first adult animal they see moving near them after hatching during the critical/sensitive learning period
Bird eggs are harder than a reptiles due to this
What is lime (or calcium)?
What is a down feather?
An example of a non-placental mammal
What is a platypus or echidna or kangaroo or koala or opossum?
What is the placenta?
Type of learned behavior in which either a stimulus or a response is linked to a reward or punishment
What is conditioning?
2 features of bird bones that make them strong and lightweight?
What are air-filled cavities and "struts" (thin strands of bone crossing the cavity)?
When the hooked barbules do not slide well and the feathers become inflexible, what will the bird do?
What is preening? OR What is dip its bill into the oil gland and run the bill over its feathers to spread the oil?
3 ways other than language which animals can communicate
What is sound, visual displays, or touch?
The time period during which an embryo develops before being born
What is gestation?
An innate behavior, triggered by a stimulus, occurring as an unchangeable, uninterrupted sequence of actions
What is Fixed Action Pattern?
A blood sample is taken from a creature's ventricle and shows it to be a mixture of O2-rich and O2-poor blood. Is it a bird or a reptile?
What is a reptile?
An example of a flightless bird
What is a penguin OR ostrich?
3 Reasons animals communicate
Warning, readiness to mate, mark/defend territorial boundaries
2 species similar are in appearance. Species 1 gives birth to offspring with little hair and are blind. Species 2 gives birth to offspring that open their eyes and have full coat of hair. Which species had a longer gestation?
What is species 2?
"Trial and error" is known as this type of conditioning
What is operant conditioning?
