BIRDS
NATURAL SCIENCE
Migration
Migration- regular seasonal movement of individuals away from, and back to the breeding grounds.
Predation and Mortality.
bar-tailed godwits have the longest nonstop flight of any bird.
Bar-headed geese migrate over the Himalayas at heights of > 7000m above sea level.
life and living
Adapted to their particular way of life
Emperor penguins have special trails that allow them to swim underwater for more than ten minutes.
Barhave such acurate hearing n owls
General characteristics of birds
Different types of birds
Evolution
Many amazing trips.
How they fly.
How they manage to raise a chick
Birds are the living descendants of dinosaurs.
Birds refilled many riches opened up by the extinction
TECHNOLOGY
Sound waves and calls
Air molecules that have been set into motion by a vibrating source.
This creates a cascade of movement that we call a pressure wave
Calls is avian vocalisation.
Calls less likely to function exclusively in mate attraction or territory defence.
Sound is the vibration of molecules.
What Technology has taught us about?
Migration
Life is better described by angle of attack, from Newton's third law of motion.
Streamlined body - helps to reduce the force of drag.
Habitats
Different shapes correspond to different trade-offs between advantages such as speed, low energy and maneuverability.
Flight
Airflow is disturbed when a wing moves through it.
Patterns
Observation
The top pattern of the wing is curved
Air divides and flows around the wing and meets up.
SOCIAL SCIENCE
Birds are either generalists or specialists.
Generalist and Specialists
Generalists eat anything; specialists specialise.
Diversity of Birds.
Birds generally have to work at foraging.
Different birds also exhibit diverse forging strategies.
Social interaction
Energetically demanding.
Birds communicated through sound.
Avian mating system.
Nests to protect and care for their young.
Defend resources and attract mates.
Bird Song
Song is often thought of as a behaviour of male birds.
Feet adapted for perching - three toes point forward, one backward.
Passerines are often called perching birds.
Females sing in the tropics.
song birds are often Passeriformes family.
More than 10,000 known bird species, around 4,000 are songbirds.
